Phoenix Contact Non-Latching Relays, REL-MR Series

Phoenix contacts REL-MR series of non-latching relays are commonly found within industrial environments, they are considered to be electrical and mechanical devices. This type of relay can often be referred to an electromechanical relay or an industrial switch.

Features & Benefits

• Pluggable miniature relays, with power contact for high continuous current

• Varied switching current dependant on the relay chosen from the REL-MR series

• Pluggable miniature relay - compact in size

• Additional hard gold plating

• AC and DC coil voltages

• Robust and hard wearing

What is a non-latching relay and how do they work?

A relay is an electrical switch that is operated by electrical pulses, their primary function is to open and close a circuit. When power passes through a circuit, a relay switches position (usually from NC to NO) using an internal coil which generates a magnetic force. This force then holds the relay in a NO position, when the current is switched off the relay returns to the NC position. This function is what makes these non-latching relays perfect for push-button applications such as keyboards and micro-controller input buttons.

A little more info

Non-latching relays support a range of signal characteristics, ranging from low voltage or current to high voltage or current and from DC to GHz frequencies.

What is the difference between a latching relay and a non-latching relay?

• When a latching relay operates its contacts, the relay holds its position, even when the supply of its operating coil has been disconnected.

• When a non-latching relay operates its contacts, the relay will reset automatically once the supply of its coil is disconnected through the internal spring mechanism.
