3132 AND 3133
ULTRA-SENSITIVE BIPOLAR HALL-EFFECT SWITCHES
These Hall-effect switches are designed for magnetic actuation using a bipolar magnetic field, i.
e.
, a north-south alternating field.
They combine extreme magnetic sensitivity with excellent stability over varying temperature and supply voltage.
The high sensitivity permits their use with multi-pole ring magnets over relatively large distances.
Each device includes a voltage
regulator, quadratic Hall voltage generator, temperature stability circuit, signal amplifier, Schmitt trigger, and open-collector output on a single silicon chip.
The on-board
regulator permits operation with supply voltages of 4.
5 to 24 V.
The switch output can...
