M118 Short stroke slim-line linear position sensor
Compact, intrinsically safe linear position sensor for mining environments. Offers high accuracy, flexible configurations and non-contact operation for confined spaces.
Key features
- Intrinsically safe for mining environments (Ex I/II M1/1GD certified)
- Compact 19 mm stainless steel housing
- Travel ranges from 2 to 50 mm, custom-calibrated
- Non-contact inductive technology eliminates mechanical wear
- High resolution with excellent linearity and EMC protection
- Sealed to IP67, operating in temperatures from -40 °C to +80 °C
Performance highlights
The M118 is a compact, non-contact linear position sensor designed for hazardous areas. Featuring a short-bodied 19 mm diameter stainless steel housing, it delivers high stability, accuracy, and repeatability across a wide temperature range. Its output is linear to the stroke, from 2 mm up to 50 mm, and factory-calibrated per specification.
Usage conditions
This model is ATEX / IECEx / UKEX certified (EX07 electronics) and suitable for gas, vapour, and dust atmospheres, including mining (Ex I/II M1/1GD). It operates between -40 °C and +80 °C and is sealed to IP67. EMC compliance, shock (40 g) and vibration (10 g) resistance ensure reliable performance in harsh conditions.
Possible applications
- Underground mining machinery
- Position feedback in safety-critical environments
- OEM compact actuators and robotics
- Intrinsically safe environments with confined space
- Rail or heavy-duty industrial automation
Advantages of choosing this product
The M118 stands out for its slim design, robust construction, and custom-calibrated stroke. Its galvanic isolation amplifier (X005) enables safe use in explosive environments. The five-wire option maintains signal integrity over long cable runs, making it ideal for remote monitoring in hazardous areas.
