Posimag, a non-contact postions sensor
Keyword: Position sensing
Position Sensor manufacturers ASM have introduced a magnetoresistive non-contact position sensor (Plate 4).
Plate 4
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.
