Magnetic sensor MSC500

Compact sensor, incremental, digital interface, resolution 1 μm

open expert video
The MSC500 magnetic sensor has a large, multi-color status LED that makes commissioning and function monitoring easier for users. The correct distance between the gage and the sensor can be visually monitored.
With the plug connection directly on the sensor head, the MSC500 is also suitable for use in very confined spaces. As a result installation is fast and simple, which naturally means lower costs. In addition, the MSC500 sensor includes all digital square wave signals. This enables evaluation of the A/B signals, the inverted signals and the periodic index signals with the same sensor.

Profile MSC500:

  • Max. resolution 1 μm
  • Max. 200000 pulses/revolution in combination with MR500 or MBR500 (160 poles)
  • Repeat accuracy ±0.005 mm
  • Status LED with integrated distance monitoring

  • Works with MB500/1 magnetic tape, MR500 magnetic ring, MBR500 magnetic tape ring
  • Reading distance ≤2 mm
  •  Sensor connection can be plugged with KV1C cable extension

  • Output circuit PP, TTL, LD (depending on the operating voltage) 
  • Optionally with reference point R or flexible reference marks FR
