In March 2024, WENSHING launched the 62GHz Radar Sensor (Model: WS-RADAR62GBY). This product utilizes 62GHz millimeter-wave radar technology, a type of microwave sensor known for its high transmission rate, large data capacity, and low latency. It offers high precision, long-range detection up to 25 meters, and strong anti-interference capabilities, enabling accurate measurement of object distances.
This product WS-RADAR62GBY also comes with an App that allows users to set the desired sensing distance via their mobile phones and displays the current measured distance within the App.
WS-RADAR62GBY is a 62 GHz mmWave radar distance sensor with a freely configurable 0.5–24.3 m detection zone. After one-click empty-zone calibration it decides whether a target is present from distance, main-signal or range-energy changes and drives its relay output directly.
A built-in Wi-Fi web interface, live trend charts, BLE and OTA firmware updates mean no PC software is needed — installation, tuning and maintenance are all done from a phone browser.
WS-RADAR62GBY does one job very well: it measures reflecting targets inside the distance zone you set, decides whether a target is present and switches its relay, or reports the actual distance. Every scenario below uses the same sensor — only the mounting position and decision settings differ.
A factory mounted WS-RADAR62GBY above a warehouse automatic door with one requirement: open only when a material-handling cart (forklift or electric pallet truck) reaches the doorway — not when people simply walk past — to cut needless door cycles, air-conditioning loss and door wear.
How: the detection zone is set to the floor area in front of the door and an empty-zone calibration is run. “Main signal” or “range energy” increase is used as the trigger condition, with the threshold tuned so that only a cart (large metal body plus load) produces enough reflection change, and a decision time of about 1 s filters out brief passers-by. When the condition is met the relay sends the open command to the door controller; a person alone stays below the threshold and the door remains closed.
Thresholds must be tuned on site with the actual carts and people; start with a single condition and fine-tune threshold and decision time using the trend chart.
A customer mounted WS-RADAR62GBY on the forklift fork carriage, facing along the forks, to tell whether a pallet or load is on the forks — and paired it with the WENSHING UWB positioning system to record automatically where every pallet is put down.
How: the detection zone covers the fork length and calibration is done with empty forks; when a pallet enters the forks, reflection distance and signal change at once and, after the decision time, the sensor outputs “loaded”.
Related systems: UWB RFID Forklift Handling System, Smart Warehouse Forklift Tracking & Route Guidance. The radar provides the loaded/empty signal; positioning and location records are handled by the UWB system.
A car-wash operator uses WS-RADAR62GBY to confirm that a vehicle is really parked inside the configured distance window of the wash bay; the wash equipment sprays only when a real vehicle is detected there.
How: start and end distances are set to the valid parking window, the distance condition is selected with a decision time, and the relay starts spraying only once the car has stopped and stays inside the window.
The decision is “is a target inside the set distance window”; whether other targets (e.g. people) trigger depends on the threshold settings, so personnel safety must still be ensured by the wash equipment’s own safety system.
A customer installed WS-RADAR62GBY beside an overhead hanging conveyor to detect each hanging product passing the sensor and count output.
How: the detection zone is set to the distance band the parts pass through and calibrated with an empty line; each product entering the zone switches the relay on and releases it when it leaves — a PLC or counter totals the relay pulses as the quantity.
The sensor outputs present/absent events; the quantity is totalled by an external PLC or counter. With a 0.5 s update cycle, parts need enough spacing — verify at your line speed.
Measures the distance down to the material surface, readable live over BLE, with a distance condition for high/low level alarms.
Feature used: Distance output (cm) + BLE + distance condition
Non-contact water-surface distance with no immersed probe; a distance threshold switches the relay at high or low level.
Feature used: Distance output + distance threshold + relay
Detects vehicles or goods standing in the doorway; the relay gives an “object under door” signal so the shutter is not lowered onto a truck.
Feature used: Calibration + decision time + relay
Non-contact detection of parts or cartons in position, unaffected by light, dust or glare; the relay wires straight into a PLC input.
Feature used: Distance decision + relay
Parking-entrance uses — barrier-gate anti-drop, dual-unit false-entry checks and tailgating alerts — pair with the WS-LPR600 AI license plate recognition camera: the radar answers “is there a vehicle in the lane?”, the camera and controller decide “who is it and may it pass?”.
Cars are the most common target for WS-RADAR62GBY: a large metal body gives a strong, stable millimetre-wave return, unaffected by night, back-light, rain, fog or headlights. The table lists vehicle applications — the radar decides “is there a car inside the set distance, and for how long”, then the relay tells the barrier gate, door operator, bay light or car-wash machine.
The worst failure of a parking, residential or factory barrier gate is dropping the arm before the car has passed. Mount WS-RADAR62GBY beside the gate facing the lane under the arm and the radar keeps checking whether a car is still there.
Set the detection window to the lane under the arm, run empty-zone calibration once with no car, and use distance or zone energy as the “car present” condition. Wire the relay to the gate controller’s safety / vehicle-present input so the arm cannot drop while a car is present.
Follow the gate maker’s instructions for the safety input and NC/NO wiring; keep the gate’s own safety features in place.
Paired with the WENSHING WS-LPR plate-recognition camera, the camera decides whether a car may enter, while the radar confirms how many cars are actually in the lane and whether the car has left.
Single unit: after one plate is admitted, if the lane stays occupied beyond the decision time, or another car enters while the arm is up, the access controller flags tailgating and triggers a beacon or buzzer. Dual units: one before and one after the gate — the controller reads the trigger order for direction; a car appearing behind the gate without a recognition record is a false entry.
Tailgating and false-entry logic runs in the access controller or PLC from the two relay signals; the radar itself outputs car / no car.
Ceiling-mounted above the bay; when a car parks the relay switches the red/green bay light or reports to the parking-guidance system so drivers see free bays from afar.
Feature used: Empty-zone calibration + distance + relay
Detects whether a charging bay is occupied and for how long; the decision time separates a quick manoeuvre from long parking for charging management and overstay alerts.
Feature used: Distance + decision time + relay
Motorcycles are irregular with small reflecting areas; combining distance and energy conditions gives a stable bay-occupied decision.
Feature used: Combined conditions + temperature compensation
Start and end distances are set in centimetres to exclude ceilings, brackets and other near-field structures; long-range measurement profiles are configured automatically.
Clear the zone and press “Apply range & auto calibrate”: a site baseline is captured within seconds and stored in flash, so it survives power cycles.
Distance change, main reflection strength and range energy can be combined, with decrease/increase direction, % threshold and decision time to suppress false triggers.
While the zone is verified empty, comparison baselines are learned per temperature (up to 60 records), keeping decisions consistent through day/night and seasonal changes.
Relay standby contact NC/NO is selectable and testable from the web UI; trigger beep can be muted, and status LEDs show network and trigger state on site.
Configure and view 24-hour trends in any browser; read distance and change parameters over BLE GATT commands; web-upload and server OTA keep settings and calibration.
No software to install: every setting is made from a phone or PC browser, with login protection and a changeable administrator password.
Current distance, main-signal change, stability score, radar temperature, network and relay status at a glance.
Drag the 0.5–24.3 m zone, calibrate with one click and set conditions, direction, threshold and decision time in one place.
1-minute to 24-hour charts of distance, main signal and range energy for evidence-based threshold tuning.
