VISION general purpose tilt sensors have a metal ball that rolls onto two electronic contacts to close a circuit when the sensor inclination rises above a user-adjustable threshold. Useful for detection of towing or trunk/hood opening, the 318-02 offers reliable tilt sensing at a price anyone can afford. Purely mechanical operation means the sensor draws zero electric current. This sensor works best when parked on a level surface. If your parking environment is not predictable, consider VISION's digital tilt sensor instead.

• This sensor does not guarantee prevention of vehicle theft.

• This sensor is compatible with all VISION security systems.

• The 318-02 is compatible with most any 3rd party car alarm.
• This sensor is not "digital" and therefore may not function as expected if your vehicle is parked on a steep incline.
