122-1-A-5/1

122-1-A-5/1 is a 122 series single pole 4mm²™ reed relay. It takes up the minimum board area making them ideal for very high density applications such as A.T.E. switching matrices or multiplexers. Requiring a board area of only 4mm x 4mm, this relay allow the highest packing density currently available. The small size of the package does not allow an internal diode. Back EMF suppression diodes are included in many relay drivers but if they are not, and depending on your 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. The device has pins on a 2 mm square pitch.
