Dependable Quality - The TEW3 exit sensor automatically opens the gate when it detects vehicles in motion. It is designed to detect a wide range of vehicles, including cars, trucks, motorcycles, and ATVs. The larger car or the faster driving speed will bring the higher sensitivity.
Hands-Free Experience - It triggers your gate opener to open the gate anytime the vehicles drive through the sensor's magnetic field of 0.61 to 3.66m. Perfect for your family and friends to go out without a remote or keypad, and enjoy wireless "Hands-Free" exit of your property.
Multiple Applications - Designed to work with TOPENS automatic gate openers. It supports any third-party gate operators whose control board provides 12-24VDC or 12-24VAC accessory power, and has Normal Open & Dry contact signal input. Highly recommended for residential, agricultural, and commercial applications.
Ingenious Design - The wand senses changes in the earth magnetic field caused by mass metal movements and then automatically opens your gate. User-friendly design, simply adjust the field area of sensitivity from 0.61 to 3.66m. by turning of a knob. Coming with 15m long directly burial cable (a PVC jacket 5-core cable), the probe should be trenched and placed next to your drive. Cable gland prevents water from entering into the wand and avoids cable damages, ensuring a long-lasting performance.
Simple Installation - Connect the wand directly to the control board of your gate operator for easy setup. The probe can be directly buried underground to save unnecessary labor cost compared with the loop coil model. No earth grounding required. Generally install the wand at least 7.5m away from the gate, and buried 5cm deep from ground and 20cm from driveway edge. Prewired weather-resistant wire and easy-to-follow instruction are included for your peace of mind.
