GENERAL INFORMATION
CAUTION
ELECTROSTATIC DISCHARGE DAMAGE
This component is sensitive to electrostatic discharge (ESD).
Take normal ESD precautions in handling this product to
prevent ESD-induced damage and/or degradation.
Failure to comply with these instructions may result in
product damage.
SOLDERING/ASSEMBLY
CAUTION
IMPROPER SOLDERING
• Ensure leads are adequately supported during any
forming/shearing operation so that they are not stressed
inside the plastic case.
• Limit exposure to high temperatures.
• Do not wave solder the SS340RT.
Failure to comply with these instructions may result in
product damage.
SS340RT Series: Use an infrared reflow process with
temperatures of 245 °C [473 °F] peak for 10 s max.
SS440R Series: PC board wave soldering temperature is
250 °C to 260 °C [482°F to 500 °F] peak for 3 s max.

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.
