Omron LZN4 relay

Status: Obsolete


Four pole telecom / signal relay, polarised, 4 pole changeover / 4 Form C / 4PDT

Product details

The  original LZN4 relay was manufactured by Omron, a relay which became a popular small signal relay. This relay has not been manufactured for many years. it is obsolete and very difficult to source.

The original datasheet for the Omron LZN4 is not available to be downloaded below. We would like to know if anyone has a copy of the original Omron LZN4 datasheet, the Panasonic NF4EB datasheet is downloadable below to aid examination of an equivalent relay specification.

Coil Voltages

Originally manufactured in coil voltages ranging from  3V to 48V dc, the most popular coil voltages used at the time in the telecomms and control industries were 5V, 12V and 24V
