NOTICE

Bipolar Hall-effect sensors may have an initial output in either the ON or OFF state if powered up with an applied magnetic field in

the differential zone (applied magnetic field >Brp and <Bop). Honeywell recommends allowing 10 µs for output voltage to stabilize

after supply voltage has reached 5 Vdc.

Note 1: The magnetic field strength (gauss) required to cause the switch to change state (operate and release) will be as specified

in the magnetic characteristics. To test the switch against the specified magnetic characteristics, the switch must be placed in a

uniform magnetic field.

NOTICE

Absolute maximum ratings are the extreme limits that the device will withstand without

damage to the device. However, the electrical and mechanical characteristics are not

guaranteed as the maximum limits (above recommended operating conditions) are

approached, nor will the device necessarily operate at absolute maximum ratings.
