HOUSING/SPACER/COVER: ABS plastic (UL94V-0), white. CONTACT RESISTANCE: 100 m Ω max. initial. DIELECTRIC STRENGTH: 200 V DC min. 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. 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: Alnico V (all models, except MPS80WG) and Ceramic Ferrite 8 (MPS80WG model only). 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. ADHESIVE MOUNTING: Foam-backed, pressure-sensitive adhesive with release liner (MPS45WGW model only). MECHANICAL & ELECTRICAL LIFE: 10 million operations.

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" Correct Configuration Center Alignment Incorrect Configuration Off Center Alignment 1/4, 1 1/4" Make Gap 1" Make Gap Detect F Dimensions are shown: Inches (mm) Specifications and dimensions subject to change F–24 www.ittcannon.com
