MT4 relay (V23104)

Cephos Electronic Circuits Ltd - CEM (UK)

MT4 relay - V23104 four pole changeover relay

Tyco MT4 datasheet

All versions of this miniature, sensitive, small signal relay manufactured by Axicom / Siemens are now obsolete, no longer manufactured, no longer available.

MT4 / V23104 Alternative: relay module C-MT4

The Cephos C-MT4 series of relay modules is the ideal replacement for the MT4 four pole small signal relay, with an identical footprint the Cephos C-MT4 relay module is a drop in alternative - no pcb modification required.

C-MT4 relay contact arrangement

The C-MT4 replacement relay module consists of two IM series relays on a 0.8mm FR4 pcb to match the original MT4 footprint together with a miniature slide switch to select the polarity of the IM series relays as the original MT4 was not polarised. This results in the need for just one replacement option for each coil voltage of either 5, 12 or 24V dc.
