X111 Linear Inductive Position Sensor

Heavy-duty version

About the X111 Linear Inductive Position Sensor

Our intrinsically safe X111 LIPS (Linear Inductive Position Sensor) incorporates electronics system EX07 which is ATEX approved for use in potentially explosive gas/vapour atmospheres. This heavy-duty version of the X101 sensor with a stronger 12.6mm push rod, recommended for applications where vibration is an issue or there is a need for longer travel sensors, mounted horizontally, and supported between rod eyes.

It remains an affordable, durable, high-accuracy position sensor designed for industrial and scientific feedback applications. The unit is highly compact and spaceefficient, being responsive along almost its entire length. The X111 provides a linear output proportional to displacement. Each sensor is supplied with the output calibrated to the travel required by the customer, from 5 to 800mm and with full EMC protection built in.

The sensor is very robust, the body and push rod being made of stainless steel for long service life and environmental resistance. Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is easy to install with mounting options including M8 rod eye bearings and body clamps.

The push rod can be supplied free or captive, with female M8 thread, an M8 rod eye, or dome end, Captive push rods can be sprung loaded, in either direction, on sensors up to 250mm of travel. The X111 also offers a wide range of mechanical options, environmental sealing is to IP65 or IP67, depending on selected cable or connector options.
