PMIS3-20-5-50KHZ Datasheet, PDF (1/9 Pages) ASM GmbH – Magnetic Scale Position Sensor

PMIS3 POSIMAG®
Magnetic Scale Position Sensor
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.
