Sensor performance unaffected by
temperature

New GT magnetic sensors based on giant magnetoresistance technology have high sensitivity over the temperature range -40 to +150C.

New GT magnetic sensors based on giant magnetoresistance (GMR) technology have high sensitivity over the temperature range -40 to +150C and are available from Rhopoint Components These sensors offer larger airgaps to the target to be sensed than competing technologies, zero speed operation and stable performance to temperatures as high as +150C, which makes them suitable for automotive and other high-temperature applications Unlike some other devices these sensors are not destroyed by any large magnetic field

The sensors are available with either an analogue, sine/cosine or digital outputs.

The digital version can be configured as a two-wire device, the output status being determined by a change in sink current.

These devices are suitable for use in applications such as the detection of gear teeth and with magnetic decoders.

A signal processing IC is available to support the analogue GT sensors, which can be located away from the sensor to allow the minimum size sensor package.

This IC eliminates offsets due to temperature, output and magnet and target variations.

This means that sensor designers can relax mechanical tolerances.

The GT sensors are available in packages as small as 2.5mm2.

Both the sensors and the signal processing ICs are available from stock. Request a free brochure from Rhopoint Components ...
