About the E505 Rotary Inductive Position Sensor

The E505 is a compact rotary sensor using non-contact inductive technology, designed for high-precision feedback in demanding environments. It ensures stable, linear output across a calibrated range and operates reliably in extreme conditions from -40°C to +80°C. The sensor offers infinite resolution and a high frequency response (>10 kHz).

Usage conditions

Certified for hazardous areas (Ex II 1GD), the E505 is intrinsically safe for gas/vapour (Zones 0–2) and dust (Zone 20), with ATEX, IECEx, and UKEX compliance. It offers full 360° shaft rotation and is designed to work with Althen’s X005 galvanic isolation amplifier for safe operation.

Possible applications

• Valve or actuator position monitoring in chemical plants
• Rotary displacement in offshore oil and gas systems
• Shaft angle feedback in industrial automation
• Motor position feedback in ATEX-classified areas
• Process control systems requiring high accuracy and reliability

Advantages of choosing this product

The E505 offers outstanding performance in a compact format, ideal for OEMs and engineers needing precise angular measurement in space-constrained or hazardous environments. Custom calibration, robust housing, and flexible mounting make integration fast and efficient.

Other important features

• Torque: <15 mNm (static)
• EMC protection to EN 61000-6-2 and EN 61000-6-3
• Output: 0.5 – 4.5 V ratiometric with 5V supply
• Various electrical connection options (cable or M8 connector)
• Flange or servo mount options
• MTBF: 350,000 hours at 40°C
