Specifications
Materials
CONTACT RATINGS: 3.0 W max. @ 30 V DC or 30 V AC max. @
0.3 AMP max.; 1.0 msec. max. operate time (including bounce);
1.0 AMP max. carry current.
HOUSING/SPACER/COVER: ABS plastic (UL94V-0), white.
CONTACT RESISTANCE: 100 m Ω max. initial.
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, 22 AWG wire: stranded, made of copper or
aluminum; Length: 12 in. with ends stripped; Color: white.
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.
POTTING (around wires): Epoxy.
MAGNETS:
OPERATING TEMPERATURE: -40°F to 212°F (-40°C to 100°C).
MPS80WGW: Ceramic Ferrite 8
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.
MPS45WGW: NdFeB
All other models: Alnico V
ADHESIVE MOUNTING: Foam-backed, pressure-sensitive adhesive
with release liner (MPS45WGW model only).
NOTE: Specifications and materials listed above are for switches with standard options.

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