MPS

MPS Series Magnetic Proximity Sensors Features/Benefits • Long life—4M operations • Sealed contacts • 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. @ 0.3 AMP max.; 1.0 msec. max. operate time (including bounce); 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).

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" Correct Configuration Incorrect Configuration Center Alignment Off Center Alignment 1/4, 1 1/4" Make Gap 1" Make Gap E Detect Third Angle Projection Dimensions are shown: mm Specifications and dimensions subject to change E–39 www.ck-components.com
