Slimline non-contact rotary sensor

Paul Boughton

ASM is introducing the PRAS20, a new non-contact, rotary position sensor in a slim 6.0mm low-profile package.

This absolute, angular position sensor features a full 360-degree measurement range in a cost-effective package. It yields a 0.5-4.5 V ratiometric, analogue output that is available either with a complete 360-degree measurement range or with smaller ranges in 15-degree increments. This wear-free design precisely measures angular displacement with an external permanent magnet

Circuitry for the sensor is encapsulated in a glass-fibre reinforced thermoplastic that provides excellent shock and vibration resistance ratings of 100 'g'/11ms shock, and 20 'g', 10Hz-2 kHz, 10 cycles vibration.

The economical, compact and ultra-thin design of the PRAS20 makes it suitable for numerous OEM motion control and process automation applications.
