UMS Series Reed Relay
The UMS Series is an ultraminiature, instrumentation-grade reed relay designed for high-density PCB layouts and precision switching in compact electronic systems. Measuring nearly 50% smaller than the standard MS Series, the UMS Series is ideal for tightly stacked matrices in test and measurement, telecommunications, and security applications.
Encased in a micro single-in-line (SIL) package, the UMS Series features SPST-NO (Form 1A) contact configuration and supports coil voltages of 5 VDC with coil resistance ranging from 400 to 500 Ω. Rated for up to 10 W, 170 VDC, and 0.5 A, it includes an internal magnetic shield and optional diode protection for enhanced signal integrity and reliability. UL certification ensures compliance with global safety standards.
