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.
Output
Incremental encoder output A/B with differential
push-pull output, TTL/RS422 or HTL compatible

= A/B with end position signal / *Z3 = A/B with reference pulse
and status signal
(Option Z3 only for non-diferential output, single ended)
Cable length (in m, standard 2 m)
Connection
S
= Cable output, open end
P
= Connector D-sub, 9 pin, at the cable end
