Performance highlights P500 Rotary inductive position sensor

The P500 rotary position sensor from Althen is built for industrial and scientific applications requiring robust, accurate angle measurement. It delivers a precise, linear analog output over a customer-defined angle (16–160°), using wear-free inductive technology. Its infinite resolution and high repeatability ensure stable performance over time.

Usage conditions

Ideal for harsh environments, the P500 withstands vibrations up to 10 g and shocks up to 40 g (IEC standards), with environmental sealing up to IP67. Designed to operate in extreme temperatures from -40 °C to +125 °C, the sensor suits a wide range of rugged applications.

Possible applications

• Industrial machinery position feedback
• Robotics and motion control
• Material testing systems
• Valve and actuator positioning
• OEM instrumentation and automation

Advantages of choosing this product

Unlike traditional potentiometers or LVDTs, the P500 uses Althen's proprietary inductive coil and ASIC technology to provide a non-contact measurement solution with no wear, excellent EMC compliance, and long service life. It supports a wide variety of output signals and mounting options for easy integration.

Other important features

• Output options include voltage (e.g., ±10V, 0.5–4.5V) and current loop (4–20 mA)
• Mechanical mounting: flange or servo mount
• Shaft options include spring return
• Optional calibration and connection configurations
• MTBF of 350,000 hours at 40 °C
