Omron is targeting a focused range of applications, including emergency lighting, heater and fan control, for flange-mounted versions of its key relay families

With flange mounting via reliable sockets, the latest MY, LY and G7L series are simpler to install and replace, simplifying maintenance and ensuring safety and critical systems stay totally operational. The versatile MY offers a host of variations including mechanical or LED operation indicators, test button, built-in diode and surge suppression facilities, and bifurcated contacts.

Switching current is 10A on two-pole versions of the MY, and four-pole models benefit from an arc barrier fitted as standard.

The miniature LY general-purpose relays are also equipped with arc barriers, offering single and dual-pole models for 100/110, 110/120, 200/220 and 220/240V AC or 100/110V DC, plus three and four-pole versions catering for operating coils rated 100/110, 200/220V AC or 100/110V DC.

All provide dielectric strength up to 2000V and built-in diode variants are also available.

These general-purpose relays are complemented by power relays in Omron's G7L series.

A wide-range AC-activated coil handles 100-110 or 200-220V AC at either 50 or 60Hz, and the design eliminates contact chatter, enabling the relays to handle momentary voltage drops up to half the rated voltage.

A miniature hinge provides maximum switching capacity, especially for inductive loads.

There are four mounting options for the G7L - quick-connect, screw, PCB terminals and DIN rail.

All offer high dielectric strength and use flame-resistant insulating materials qualified to UL94V-0.
