  • Quality construction
  • Quick and easy installation Typical Applications
  • Automotive sensors and indicators
  • Industrial sensors
  • Factory automation equipment Specifications CONTACT RATINGS: 3.0 W max. @ 30 V DC or 30 V AC max. @ 1.0 AMP max. carry current. 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, 22 AWG wire: stranded, made of copper or aluminum; Length: 12 in. with ends stripped; Color: white. POTTING (around wires): Epoxy. MAGNETS: MPS45WGW: NdFeB MPS80WGW: Ceramic Ferrite 8 All other models: Alnico V ADHESIVE MOUNTING: Foam-backed, pressure-sensitive adhesive with release liner (MPS45WGW model only).

E E–39 Dimensions are shown: mm Specifications and dimensions subject to change www.ck-components.com Third Angle Projection MPS Series Magnetic Proximity Sensors 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 sep- aration 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,
