Series Features
MS Series Reed Relay
Series DescriptionThe MS Series is a general-purpose micro single-in-line (SIL) reed relay designed for instrumentation-grade performance in compact and high-density PCB layouts. Encased in a rugged thermoset overmolded package, the MS Series features a standard internal magnetic shield and is ideal for stacking in close matrices. A high-frequency version is available, supporting switching up to 1 GHz, making it suitable for precision signal routing in test and measurement environments.
Available in SPST-NO (Form 1A) and SPST-NC (Form 1B) contact configurations, the MS Series supports coil voltages of 5 VDC and 12 VDC, with coil resistance ranging from 280 to 700 Ω. It is rated for up to 10 W, 200 VDC, and 0.5 A, and offers optional diode protection for coil suppression. UL approval ensures compliance with safety standards for industrial and commercial applications.
