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
