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.

E E–31 Dimensions are shown: inches (mm) Specifications and dimensions subject to change www.ckswitches.com MPS Series Magnetic Proximity Sensors Third Angle Projection 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” Correct Configuration Incorrect Configuration Center Alignment Off Center Alignment 1 1/4" Make Gap Make Gap 1/4,
