The P111 is a rugged, heavy duty version of the P101 with a significantly stonger 1/2" pushrod. The P111 is particuarly well suited to applications where vibration is an issue or where the requirement is for a long travel sensor, horizontaly mounted and supported by rod eyes.
It remains an affordable, durable, high accuracy linear sensor designed for industrial and scientific feedback applications. The highly compact and space efficient unit is responsive along almost all of its length.

Like all Positek sensors the P111 provides a linear output that is proportional to the displacement. Each unit is supplied calibrated to the exact travel required by the customer, the P111 is available with any travel from 0-5mm to 0-800mm, for example, if your application requires 10" (254 mm) measurement then Positek will manufacture the sensor specifically for this length. The mechanical length and calibration will be set up for 254 mm.

The sensor is very robust, the body and push rod are made from stainless steel for good environmental resistance and service life. This product is well suited to OEM customers looking for good sensor performance in arduous applications such as industrial machinery where cost is important. Overall performance, repeatability and stability are outstanding over a wide temperature range.

The sensor is easy to install with mounting options that include M8 rod eye bearings and body clamps. The push rod is normally supplied captive but can be supplied free if required. The push rod is supplied with either; M8 rod end, M8 female thread or with a dome end.

The P111 is sealed to either IP65/IP67 depending on which connector/cable option. The sensor has fully integrated EMC protection.
