P117 Slim-line linear position sensor

Compact and highly durable linear sensor with inductive technology for precise position feedback in industrial and scientific environments.


Key features

  • Non-contacting inductive technology eliminates wear and extends lifespan
  • Factory-set measurement range from 5 mm to 350 mm
  • Compact 19 mm diameter stainless steel body
  • Sealed to IP67 for harsh environments
  • Linear output, high repeatability and temperature stability
  • Multiple output options: analog voltage, current, or ratiometric

About the P117 Slim-line Linear Inductive Position Sensor

The P117 is a slim-line, cost-effective linear position sensor engineered for high-precision feedback in challenging industrial and scientific environments. With a body diameter of only 19 mm and travel lengths customizable up to 350 mm, it is ideal for applications where space, reliability, and performance are critical.

Inductive technology for long life

Althen’s proprietary inductive technology delivers DC analog output with no contact between moving electrical parts, eliminating wear and maximizing service life. The sensor offers infinite resolution, minimal noise (< 0.02% FSO), and a frequency response >10 kHz, making it well-suited for high-speed and high-accuracy measurements.

Flexible esign & mounting options

The P117 can be configured with:

  • Captive or non-captive push rods
  • Spring extension or retraction
  • Push rod tips: threaded, domed, rod-eye, or magnetic
  • Connection options: axial/radial cable glands or M12/M8 connectors

Mounting is simplified with M5 male studs, rod eye bearings, or optional body clamps. IP67-rated sealing ensures durability in harsh conditions.

Application areas

  • OEM machine builders requiring slim, accurate sensors
  • Feedback control in automation and robotics
  • Scientific instrumentation with compact form factor needs
  • Position sensing in hydraulic, pneumatic or electromechanical systems
