Installation Instructions for the

SS490 Series Miniature Ratiometric
Linear Hall-Effect Sensor ICs

SOLDERING INSTRUCTIONS

NOTICE

Do not wave solder surface mount sensor ICs (catalog listings
with suffixes -S or -SP). Wave soldering may negatively affect
sensor performance and reliability, and will void Honeywell’s
warranty.

Surface mount (catalog listings with suffixes -S or -SP): Use
infrared reflow process with active flux, lead-free solder. Do not
exceed peak temperature of 245 °C [473 °F] for a maximum of 10
seconds.

Through-hole leads: Wave solder at 250 °C to 260 °C [482 °F to
500 °F] for a maximum of 3 seconds. Burrs are allowed only if full
length of leads will pass through hole.

CLEANING INSTRUCTIONS

CAUTION

PRODUCT DAMAGE

Use agitated rinse, not pressure wash, in order to avoid forcing
contamninats into the sensor package.

Failure to comply with these instructions may result in
product damage.

Supply voltage (Vs) -0.5 Vdc to 11 Vdc
Output current 10 mA

Storage temperature -55 °C to 165 °C [-67 °F to 329 °C]

Magnetic flux

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.
