About the P106 Internally mounted linear sensor

In-Cylinder Sensing for Constrained Installations. The P106 is a robust, compact linear sensor designed to be mounted inside a hydraulic or pneumatic cylinder, with an external electronics module for easy access and flexible installation. It is ideal for OEMs where internal space is limited, but high accuracy and reliability are essential.

Non-contact inductive sensing for long life

Using Althen’s inductive sensing with ASIC control, the P106 offers absolute position feedback with infinite resolution and no wear. The sensor probe is inserted into the cylinder, and the electronics module is mounted externally using either threaded or flanged housing (see illustrations on page 6).

Other important features

Contactless inductive technology for long service life
Custom-calibrated stroke length (5 to 800 mm)
Rugged stainless steel probe and IP65/IP67-rated electronics
External electronics module with multiple mounting options
Wide range of outputs: voltage and 4–20 mA
Ideal for space-constrained OEM cylinder designs

Flexible electrical and mechanical integration

Each P106 unit is factory-calibrated to a customer-defined travel (5–800 mm) and supports multiple output types:

0.5–4.5V, ±5V, ±10V
0.5–9.5V
4–20 mA (2-wire or 3-wire)
Options include M18x1.5 threaded mount or flange with dual slot pattern. Target tubes can be mounted in the piston using welded or adhesive flanges (see page 7).

Rugged and ready for harsh environments

The P106 is constructed with stainless steel housing, sealed to IP65/IP67, and tested for 350 bar pressure, 10 g vibration, and 40 g shock resistance. Full EMC compliance ensures reliable signal integrity under industrial conditions.

Applications

In-cylinder stroke feedback for hydraulic actuators
Pneumatic system monitoring
OEM machinery where internal installation space is limited
Retrofit or upgrade of cylinder systems with external electronics access
