POSIMAG, a non-contact Position Sensor.
Position Sensor manufacturers ASM have introduced
a magnetoresistive non-contact position sensor.
The new recently developed sensor designated Posimag uses a compact
non-contact sensor head which moves above a magnetic strip. It is robust
and fast, and has high resistance to dust, moisture and many fluids.
A choice of configurations is possible and resolution to within 5 microns
can be achieved. Power supply to the sensor can be between +5v and
+30v to produce an equivalent incremental encoder output with differential
push-pull for compatibility with LD, TTL, HTL and CMOS.
