## Description

TOPENSTEW3 Vehicle Exit Sensor Kit Wired Exit Wand Driveway Car Vehicle Detector with 50 ft. Cable Range Adjustment for Automatic Gate Opener Systems Hands Free Auto Sensor Probe Device

## Features

- 【Reliable Quality】Automatically triggers your gate operator to open when the TEW3 exit wand detects moving vehicles exiting property. The probe allows the vehicle to drive past the sensor's magnetic field of 2 to 12 feet, then activates your gate. Perfect for your family and friends to go out without a remote or keypad. The bigger car or the faster driving speed, the more sensitive wand will be.
- 【Multiple Applications】Designed specifically for TOPENS gate openers (Except for AT602, RK700, CK500 and CK700 model) by providing hands-free operation. While TEW3 wand is also compatible with many other brands’ automatic gate opener systems with 12-24 Vdc or 12-24 Vac accessory power available, and Normal Open & Dry contact signal acceptable. Recommended for residential, agricultural, and commercial applications. It detects vehicles (cars, trucks, motorcycles, ATV's, etc.)
- 【Clever Design】The wand senses a change in the earth magnetic field caused by a mass of metal in motion and then automatically opens your gate. Comes with directly burial 50 ft. long cable (a PVC jacket 5-core cable). Cable gland protection prevents water from entering into wand and avoid cable damages. User-friendly design, adjust sense range from 2 to 12 ft. with simple turn of a knob. More lightning protection provides a longer operating life.
- 【Easy to Install】Connects directly to the control board of gate operator. Its probe can be directly buried underground to save unnecessary labor cost compared with loop coil model. No earth grounding required. Generally install the probe at least 25 ft. away from the gate. Just bury the wand 2” deep from ground and 8” from driveway edge. Prewired weather-resistant wire and easy-to-follow instruction are included for your peace of mind.
- 【Outstanding Customer Service】Backed by a 12-month TOPENS Warranty, and free product return & exchange service within 30 days. More than an accessory, our complimentary TopensCare+ Customer Support provides you comprehensive system solutions. Simply contact us via TOPENS official website for any concerns during product installation and use. We are quite sure that you will be super-impressed with high quality of our accessories.
