Product Description

Product Overview

The Littelfuse DRS-50 is a standard, normally open (Form A) high-power reed switch designed for demanding applications. Featuring a hermetically sealed glass envelope, it offers robust performance with the capability to switch high voltages and power up to 400Vdc at 2mA, carrying up to 6A and handling 100W/VA. Its high insulation resistance and low contact resistance ensure reliable operation. Ideal for security, limit switching, industrial applications, and white goods, the DRS-50 provides a dependable solution for switching European mains voltage with zero operating power required for contact closure.
