About the P111 - Rugged stand-alone Linear Inductive Position Sensor

Performance highlights

The P111 linear position sensor uses Althen’s proprietary non-contact inductive technology, providing long service life and eliminating wear typically associated with contacting elements. It delivers a high-frequency response (>10 kHz) and linear output proportional to displacement.

Usage conditions

Built for demanding industrial environments, the P111 features a robust stainless steel body and push rod (Ø 12.6 mm), with optional IP65 or IP67 environmental sealing. It operates reliably in temperatures from -40 °C to +125 °C and withstands 10g vibration and 40g shock.

Possible applications

Industrial machinery and automation systems
OEM integration for displacement feedback
Test benches and material fatigue monitoring
Systems with high vibration and long-stroke requirements

Advantages of choosing this product

Customizable stroke length to fit precise application needs
Proven reliability with MTBF of 350,000 hours at 40 °C
Easy integration with multiple mounting and connector options
Offers options for spring-return and magnetic tip
Ideal for high-performance, cost-sensitive environments
