Very compact sensor for industrial applications

Sensor head PMIS3

• Non-contact, no wear

• High velocity

• Robust shielded metal enclosure

• Protection class IP67

• Incremental encoder output A/B/Z

• Signal processing as usual with encoders

• Reference pulse and end position signal

• Indicator for velocity/position errors

A POSIMAG measuring system consists of the

sensor head PMIS3 and the magnetic scale PMIB3

with the same magnetic period.
