## **Specifications** 

CONTACT RATINGS: 200mA @ 3W, 15 VDC CONTACT RESISTANCE: 300 m Ω max. initial. DIELECTRIC STRENGTH: 150V DC min. 

ELECTRICAL CIRCUIT: SPDT NO/NC (Contact Form C). Reed switch normally open contact opens when magnet is removed from proximity. Normally open contact contacts are held closed when magnet is within actuation range. 

OPERATING TEMPERATURE: -40°F to 176°F (-40°C to 80°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: 2 million operations. 

## **Materials** 

HOUSING/SPACER/COVER: Aluminum, black. 

REED SWITCH: Rhodium coated reed contacts in hermetically sealed, nitrogen filled glass capsule. Used in closed loop circuits. 

WIRE LEADS: UL 1061/ UL1007 / UL2468 

All are 22 AWG wire: stranded, made of copper or 

aluminum; Length: 2 meters with ends stripped; Jacket: Stainless steel. 

POTTING (around wires): Epoxy. 

MAGNETS: NdFeB 

**NOTE:** Specifications and materials listed above are for switches with standard options. For information on specific and custom switches, consult Customer Service Center. 

PACKAGING: Bulk packaging, 1 switch and magnet pairs per package. 

## **How To Order** 

Our easy build-a-switch concept allows you to mix and match options to create the switch you need. To order, select desired option from each category and place it in the appropriate box.

## **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. 

**Correct Configuration Incorrect 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”
