Highlights

Switching wattage configurable from 80W to 120W  Glass sealed on round portion of wire for high seal strength  Flattened leads oriented to contact  Sputtered Ruthenium contact  RoHS Compliant and Lead-free  Not Sensitive to ESD  40-120 Operate AT band

Description

This reed switch is physically robust and can switch up to 120W. The two types of contact ratings available cover a wide range of high wattage applications. When supplied in a release AT group and used Normally Closed with a biased magnet, it is especially useful in elevator and hoist applications. Close differential characteristics can also be built into this reed switch. In addition to the standard Normally Open configuration, we can also supply this reed switch in a normally-closed or a latching form. This reed switch is completely Lead-free and conforms to the RoHS directive.

Applications

This reed switch is suitable for use in the following applications and in many others: elevators and hoists, transformer tap changers, high voltage reed relays
