G500 Intrinsically Safe Rotary Position Sensor

Compact, EX-certified rotary sensor for angular position feedback in Zone 0 / Division 1 environments.

Key features

Certified for Zone 0 / Class I Div 1 (EX ia IIC T4 Ga)
Non-contacting inductive rotary sensing (wear-free)
Angle calibration: 16° to 160° (customer-defined)
Infinite resolution, low torque, high stability
Output: 0.5–4.5 V ratiometric (EX08 electronics)
Full EMC compliance, IP65 or IP67 sealed
Servo or flange mounting options

Performance highlights

The G500 rotary position sensor is a CSA-certified, intrinsically safe sensor for hazardous gas/vapour environments, ideal for use in Zone 0 or Class I, Division 1 areas. It uses a non-contacting inductive technology, offering wear-free operation and excellent long-term stability. The sensor is supplied calibrated to a specific angle (between 16° and 160°), and delivers a linear analogue output (0.5–4.5 V) via EX08 electronics.

Usage conditions

The G500 features robust stainless steel housing (Ø35 mm), is sealed up to IP65/IP67, and offers high vibration/shock resistance (10 g / 40 g). It operates in a wide temperature range of -40°C to +80°C and complies with EN 61000-6-2 / -6-3 EMC standards.

Applications:

Valve position feedback in hazardous zones
Rotary control in chemical or petrochemical systems
ATEX-rated test benches and actuators
OEM machinery with angular displacement feedback
Servo and motor shaft position sensing

Why choose the G500?

This sensor combines precision and ruggedness, with infinite resolution, high frequency response (>10 kHz) and low torque (<20 mNm). It’s easy to mount via servo or flange. Standard configuration includes:

Factory-set rotation range (16°–160°)
IP65 or IP67 sealing via connector or cable gland
Galvanic isolation compatibility (G005 amplifier)
Optional spring return shaft up to 100°
