UMS Reed Relays

UMS Reed Relays

Looking for a drop-in repcament SIL for very close stacking matrices?

At nearly half the size of the standard MS series, the new UMS Relay Series from MEDER measures only 9.5 x 3.6 x 6.85mm. Though nearly 50% smaller, the UMS relays offer the same electrical characteristics as its larger SIL relay equivalent.

Specifically designed with a slim molded body and internal magnetic shield, these UMS relays can be used in very closely stacked matrices often required in test and measurement applications.

In addition to the internal magnetic shield, the UMS relays also contain an internal diode used to protect the integrated Reed Switch. The UMS Series reach a contact rating of up to 10W with a maximum switching voltage of 170V and carry current of 1A maximum.

Keeping with the standard (SIL) single in-line packaging, the UMS relays provide a drop-in replacement SIL requiring less PCB space.
