M117 Slim-line linear position sensor
Compact, intrinsically safe linear position sensor for mining and hazardous areas. Designed for robust performance and flexible installation in limited space.
Key features
- Certified intrinsically safe for mining and explosive environments (Ex I/II M1/GD)
- Slim 19 mm stainless steel housing for space-constrained applications
- Non-contact inductive technology for extended sensor life
- Configurable measuring range from 5 to 350 mm
- High accuracy ≤ ±0.25% FSO and infinite resolution
- IP67-rated housing with various mounting and connector options
Performance highlights
The M117 slim-line linear position sensor delivers reliable performance under harsh industrial and mining conditions. It uses proven inductive technology to provide a linear, wear-free output proportional to stroke. With outstanding accuracy, temperature stability and repeatability, it’s ideal for OEMs requiring reliable sensor feedback in hazardous areas.
Usage conditions
Designed with EX07 electronics, the M117 is ATEX / IECEx / UKEX approved and certified for Ex ia I/II M1/GD zones, making it suitable for both gas and dust atmospheres. It operates within a wide temperature range from -40°C to +80°C and maintains performance even under vibration, shock and EMI exposure. Environmental protection is ensured through IP67 sealing.
Possible applications
- Mining and underground vehicles
- Hydraulic cylinders
- Material handling equipment
- Industrial automation in hazardous zones
- Position monitoring in harsh outdoor environments
