ELPM linear position sensor has improved sealing optionVariohm EuroSensor’s ELPM motorsports series linear position sensor is well proven over several years for demanding applications that include ride height, suspension displacement and steering angle measurement. Recent developments to the IP67-rated sensor, which is UK designed and manufactured by Variohm, includes an optional internal dual-lip seal arrangement that offers enhanced reliability and improved endurance. The option will suit all areas of motorsports as well as industrial applications where unpredictable wet and hostile environmental conditions may exist - where fit-and-forget dependability, uncompromising reliability and topmost performance is an imperative.

The S option (ELPMS) is available across the full range of the sensor series, covering electrical stroke lengths from 12.5mm to 175mm (in 25mm increments) for both the standard self-aligning pivot bearing version and the ‘Pop’ version that includes snap-on mountings for rapid installation or removal. Furthermore, the improved sealing option does not increase the 9.5mm diameter cylindrical housing or the overall mounting length which is shorter and more compact than competitive linear sensor devices. The independent linearity across the range is +/-1 per cent for the 12.5 to 50mm versions and +/- 0.5 per cent for the 75 to 175mm versions. The ELPM has a temperature range of -30degC to +150degC continuous with a short-term rating to 175degC.

Rated at 25 million operations and with a maximum speed of 10m/sec, the long life and high reliability of the ELPM and ELPMS series is the similarly due to the patented multi-fingered precious metal wiper system which maintains full and complete contact with the linear sensor’s conductive plastic resistance element – even under the most arduous physical and environmental conditions and with very low electrical noise. The 24V DC supplied sensor has a recommended wiper current of only 10 uA for maximum efficiency in battery powered use and is supplied as standard with a 500mm free cable with a Viton seal.

The ELPM series is also available with a spring loaded shaft and protective covers – custom options for stroke length, mounting and electrical connection are available on request. Go to to learn more about Variohm’s ELPM motorsports series linear position sensor.
