Specifications
CONTACT RATINGS: 50V AC/DC 50/60Hz 5W (0.25A maximum)
RESISTIVE
CONTACT RESISTANCE: 100 m Ω max. initial.
DIELECTRIC STRENGTH: 200 V DC min.
ELECTRICAL CIRCUIT: SPST NO (Contact Form A). Reed switch
opens when magnet is removed from proximity. Contacts are
held closed when magnet is within actuation range.
OPERATING TEMPERATURE: -40°F to 212°F (-40°C to 100°C).
OPERATING DISTANCE/ALIGNMENT: Operate (pull-in or make)
points are nominal values with ± 10% tolerance. Release points
are 110% to 150% of the operating points.
MECHANICAL & ELECTRICAL LIFE: 4 million operations.
PACKAGING: Bulk packaging, 10 switch and magnet pairs
per package.
Materials
HOUSING/SPACER/COVER: ABS plastic (UL94V-0), white.
REED SWITCH: Rhodium coated reed contacts in hermetically
sealed, nitrogen filled glass capsule. Closed when magnet is in
close proximity. Used in closed loop circuits.
WIRE LEADS: UL 1061/ UL1007 / UL2468
All are 22 AWG wire: stranded, made of copper or
aluminum; Length: 12 in. with ends stripped; Color: white.
POTTING (around wires): Epoxy.
MAGNETS: NdFeB
ADHESIVE MOUNTING: Foam-backed, pressure-sensitive adhesive
with release liner.
NOTE: Specifications and materials listed above are for switches with standard options.

Actuating Positions
When installing recessed and surface mount contacts, magnet position
is very important. The switch and magnet must always be parallel or
end to end, and never in a ‘T’ configuration.
Gap Distance
Gap distance is a combination of the horizontal and vertical plane
separation of the switch and magnet. Example: if a recessed magnet
is 1/4” off the centerline of the switch, the make gap is reduced by
1/4”
