Linear Position Sensor L3

The Everight Sensors L3 is an extremely robust linear position sensor designed to be embedded in, or port mounted to, a hydraulic cylinder, and reliably provide an analog current or voltage (SSI available as OEM option) output over the sensor’s measuring range while operating in a fluid power environment.

The Everight Sensors L3 is an extremely robust linear position sensor designed to be embedded in, or port mounted to, a hydraulic cylinder, and reliably provide an analog current or voltage (SSI available as OEM option) output over the sensor’s measuring range while operating in a fluid power environment. Based on Everight’s proprietary, contactless NyceWave™ inductive sensing technology, the L3 employs a unique solid probe construction that is extremely robust when subjected to intense shock and vibration, and only requires a simple conductive tube target (or simply the gun drill ID of the cylinder rod) for operation, rather than a magnet or some other special target type. Contactless sensors such as the L3 are not subject to wear and experience no output signal deterioration over the life of the sensor. Field programmability is available on the L3.
