120-1-A-5/2 is a 120 series low level single pole 4mm² � reed relay. This relay range takes up the minimum board area making them ideal for very high density applications such as A.T.E. switching matrices or multiplexers. It requires a board area of 4mm x 4mm, this relay allow the highest packing density. The small size of the package does not allow an internal diode. The back EMF suppression diodes are included in many relay drivers and depending drive methods, these may have to be provided externally. While socketing relays is not normally recommended due to the risk of affecting contact resistance integrity, it is appreciated that sockets may sometimes be desired for ease of servicing/replacement, in the case of a relay being damaged or reaching the end of its working life. There are suitable connectors available from some manufacturers, both SMD and through hole, that will allow these relays to be stacked in either a row or in a matrix on a 4mm pitch.
