The MSK320R contains two sensor elements and two signal conditioners, therefore providing two independent output signals A1. A2. B1 and B2 as well as the associated inverted signals /A1. /A2 /B1 and /B2. Combined with a safe input card, the sensor can be used in the overall system up to Performance Level PLd.

Enhanced safety owing to independent output channels
2 magnetic sensors and 2 signal conditioners in one sensor head
Small, space-saving housing
Reading distance ≤2 mm
Repeat accuracy of ±1 increment
Great application temperature range of -40 … 85° C
Optionally available with Deutsch connectors
Cost advantage by installation of one MSK320R sensor instead of two MSK320 sensors
