Soldering temperature and time

PC board wave soldering process: 250 °C to 260 °C [482 °F to 500 °F] for 3 s max.

NOTICE

These Hall-effect sensor ICs 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 after supply

voltage has reached 3 V for the output

voltage to stabilize.

NOTICE

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

limits, the switch must be placed in a

uniform magnetic field.
