P117 Linear Inductive Position Sensor

LIPS P117 Slim-Line Linear Position Sensor

About the P117 Linear Inductive Position Sensor

Our P117 (Linear Inductive Position Sensor) is an affordable, durable, high-accuracy position sensor designed for industrial and scientific feedback applications. It is particularly suitable for OEMs seeking good sensor performance for arduous applications such as industrial machinery where cost is important. Overall performance, repeatability and stability are outstanding over a wide temperature range. The unit is very compact and space-efficient with a small 19mm diameter body. The sensor is very robust, the body and push rod being made of stainless steel. The sensor is easy to install with mounting options including M5 male stud and M5 rod eye bearing. The push rod can be supplied free or captive, with male M5 thread or M5 rod eye.

The P117 provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 10 to 300mm and with full EMC protection built in. The P117 offers a range of mechanical options, environmental sealing is IP67.

How PIPS technology eliminates wear for longer life
PIPS technology is a major advance in displacement sensor design. PIPS-based displacement transducers have the simplicity of a potentiometer with the life of an LVDT/RVDT.

PIPS technology combines the best in fundamental inductive principles with advanced micro-electronic integrated circuit technology. A PIPS sensor, based on simple inductive coils using ASIC control technology, directly measures absolute position giving a DC analogue output signal. Because there is no contact between moving electrical components, reliability is high and wear is eliminated for an exceptionally long life.

PIPS overcomes the drawbacks of LVDT technology bulky coils, poor length-to-stroke ratio and the need for special magnetic materials. It requires no separate signal conditioning. Our LIPS range are linear sensors, while RIPS are rotary units and TIPS are for detecting tilt position.
