M505 Slim-Line rotary sensor (intrinsically safe)
Compact and durable rotary sensor for hazardous mining and industrial environments. Offers precise angle measurement, full EMC protection and long service life.
Key features
- Intrinsically safe for use in gas, dust and mining environments (Ex I/II M1/1GD)
- Factory-set angle range between 15° and 160°
- High accuracy and temperature stability over wide ranges
- Non-contact inductive technology for extended service life
- Compact 19 mm diameter design for tight spaces
- Full EMC protection, sealed to IP67
Performance highlights
The M505 Slim-Line rotary sensor offers reliable and repeatable performance in demanding environments. Built with non-contact inductive technology, it ensures minimal wear and high linearity (≤ ±0.25% FSO @ 20°C) across a wide temperature range. With infinite resolution and a frequency response over 10 kHz, it provides fast and accurate feedback for angle measurement.
Usage conditions
This sensor is certified for intrinsically safe operation in hazardous gas and dust zones (Ex ia IIC T4 Ga, Ex ia IIIC T135°C Da, Ex ia I Ma). It operates in temperatures from -40 °C to +80 °C and is sealed to IP67, making it suitable for rugged industrial and mining settings. The stainless steel housing and minimal torque (<15 mNm) contribute to durability and low energy consumption.
Possible applications
- Underground and surface mining equipment
- Hazardous industrial automation systems
- OEM machinery with space constraints
- Scientific test setups with safety requirements
- Material handling in explosive zones
