Tilt switch with adjustable tilt sensor angle threshold

These sturdy and reliable tilt switches use a solid state precision tilt sensor at the heart of this tilt angle warning system. One of main applications is for the prevention of vehicle rollover. Vehicle rollover is a problem that is faced by many industrial, agricultural and commercial vehicles, such as ride on mowers, tractors, telescopic handlers, telescopic and scissor lift platforms and all types of cranes.

These Electronic Tilt Switch modules are high accuracy low cost tilt switches. Three main types are available, single axis, dual axis and omni-directional. For each of these types there are four versions to cover a variety of switching angles. The exact switching angle can be adjusted with the pcb mounted rotary switches. With the dual axis version the tilt threshold (the trip angle) can be adjusted individually for the X and Y axis. With the single axis version, only the X axis is monitored, and with the omni-directional version, the measurement of both axis is combined to calculate the resultant tilt angle. Once the tilt threshold is reached the relay operates and the switch contacts are closed. This can be used to sound an alarm, switch on a warning light, or interface directly to a machines control system. The units incorporate analogue and digital filters to give a response suitable for vehicle tilt monitoring.
These tilt switches are highly configurable, and can be easily modified for any given application, so please contact us with your specific requirements.
