PMIS3 POSIMAG®
Magnetic Scale Position Sensor
Very compact sensor for industrial applications
Sensor head PMIS3
• t Non-contact, no wear
•t High velocity
•t Robust shielded metal enclosure
•t Protection class IP67
•t Incremental encoder output A/B/Z
•t Signal processing as usual with encoders
• t Reference pulse and end position signal
•t 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.
Output
Incremental encoder output A/B with differential
push-pull output, TTL/RS422 or HTL compatible
