Variohm ELP Linear Position Sensors

ELP webA range of miniature linear potentiometers designed to operate in extreme conditions, all sensors are fitted with ‘O’ ring sealed shafts to provide IP67 sealing. Various connector types and internal electronics which are not sensitive to moisture ingress.






Typical uses are ‘suspension movement’, steering angle, throttle position, etc. This specially modified version uses larger 5mm rod ends, for longer life and to retain compatibility with existing installations.

The compact size of the ELP series makes them ideal for shock and fork position sensing in competition motor bike applications. Typically a 50-75mm unit is used on the rear and a 150mm on the fork.

Common applications include damper position, throttle position, steering angle, clutch travel, etc.
