- Resolution max 1 um
- Wide range of supply voltage 4-30 V DC
- Measurement length up to 20 m.
- The distance between the sensor and the tape is 1mm
- Insensitive to dirt, dust, water IP67
- High resistance to shocks, vibrations, pressure
- Anodized aluminum housing
- Polyurethane belt chip scrapers
- Optional cable in a metal conduit
- LED diode indicating incorrect signal level
- Mounting with 2 M3 screws
The MSI-21 magnetic sensor together with the MT20 tape or magnetic wheel creates an incremental measuring system designed for direct measurement of linear displacement, rotation and rotational speed. The measurement is non-contact and does not have any wearing parts (bearings, seals, etc.). The sensor can be mounted up to 1 mm from the tape or wheel. It is completely insensitive to dirt, dust, water and oil. The output is a quadrature signal, 2 channels shifted in phase by 90 degrees.
Magnetic encoders are an excellent solution in harsh environments, including woodworking, stone, metalworking, textiles, printing, packaging, plastics processing, automation and assembly systems, laser / water cutting, electronic assembly equipment, etc.
Technical data:
Ordering:
MSI-21 – A – B – C
A – resolution in um (1 , 2 , 4 , 5 , 10 standard , 25 , 50)
B – scrapers (1 – with scrapers; 0 – without scrapers)
C – metal conduit (1 – with metal conduit; 0 – without metal conduit)
Example:
MSI-21 – 10 – 0 – 0 means sensor with resolution 10 um (0,01mm) without scrapers and without metal conduit
