Specifications

  1. 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.
  2. CONTACT RESISTANCE: 100 m Ω max. initial.
  3. DIELECTRIC STRENGTH: 200 V DC min.
  4. 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.
  5. OPERATING TEMPERATURE: -40°F to 212°F (-40°C to 100°C).
  6. 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.
  7. MECHANICAL & ELECTRICAL LIFE: 10 million operations.
  8. PACKAGING: Bulk packaging, 10 switch and magnet pairs per package.

Materials

  1. HOUSING/SPACER/COVER: ABS plastic (UL94V-0), white.
  2. 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.
  3. WIRE LEADS: UL 1061, 22 AWG wire: stranded, made of copper or aluminum; Length: 12 in. with ends stripped; Color: white.
  4. POTTING (around wires): Epoxy.
  5. MAGNETS:
    MPS45WGW: NdFeB
    MPS80WGW: Ceramic Ferrite 8
    All other models: Alnico V
  6. ADHESIVE MOUNTING: Foam-backed, pressure-sensitive adhesive with release liner (MPS45WGW model only).
