MM1200

Signal Relays

The world‘s workhorse signal relay.

The MM1200 is a 6-channel SPST signal relay perfect for high-density LF switch matrices in any industry. In general, it is the ideal replacement for any space-wasting electromechanical relays and reed relays.

MM1200

6-channel SPST Signal Relay

The MM1200 is a 6-channel SPST high-performance signal relay that can be used for high-density signal switching applications in both AC and DC circuits and is meant to replace electromechanical signal relays or reed relays. Typical applications range from medical equipment, DC switch matrices/multiplexers, to test & measurement equipment.

The MM1200 is capable of 1.0 A per channel steady state, and delivers low on-state contact resistance and high off-state isolation with >3 billion switching cycles and <10µs switching times.

Each switch is Normally Open (NO) and individually controlled by a digital serial-to-parallel Interface. An external +5 VDC logic supply and high voltage +79 VDC bias source are required for the operation of the internal switch driver.

85% PCB area reduction and 75% build height reduction together with lower weight enables new form factors for relay and switch matrix boards.

MM1200 vs Electromechanical Relays
Imagine the impact this will have on test & measurement boards, which often require 250+ EMRs. The Ideal Switch will dramatically decrease the T&M machine size and increase its reliability.
