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.

• 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

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.

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.

• 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.

When you need to switch two independent signals in tandem, this non-latching relay from Phoenix Contact reacts at the press of a button. It has a double pole, double throw (DPDT) configuration, which means it switches the circuit when energised and returns to its initial state when the power is released. Compact dimensions of 15.7 (depth) x 29 (height) x 12.7mm (length) mean it can be easily mounted on a printed circuit board (PCB). Through-hole termination provides strong mechanical bonds and electrical connections.
This device is built with a robust design, so you can rely on it for a long service life. Gold-plated contacts resist corrosion to ensure maximum conductivity and maintain the quality of the signal. As you can switch the relay with input voltages ranging from 5V to 250V AC/DC, it's a versatile choice for use with the UK mains supply or any of the lower-voltage power supplies that are common in industrial setups.

• Operating temperature range of -40°C to +85°C for use in harsh environments
• Mechanical service life of 30,000,000 cycles means it delivers long-term performance
