Omron LY2 110/120VAC Socketed Relay: Technical Guide, Applications and Installation

Picking the right component for a control panel takes more than scanning a catalogue. The Omron LY2 110/120VAC is a Socketed Relay that has earned its place on the shortlist of engineers who value long service life over a bargain price — particularly in control panels applications.

Omron’s product range extends well beyond relays and switches. The company’s Omron Sensor portfolio covers inductive, photoelectric, and capacitive detection technologies — often integrated into the same panel alongside units like this one, creating a fully cohesive control system.

What Is the Omron LY2 110/120VAC Socketed Relay?

The Omron LY2 110/120VAC is a Socketed Relay rated at 110/120V AC, built to handle control panels reliably over a long service life. Key engineering features include arc barrier, compact body, wide socket compatibility, and the unit mounts via socket + din rail or pcb.

What separates this unit from generic alternatives is in the details: arc barrier, compact body, wide socket compatibility. The coil operates at 110/120V AC, making it straightforward to match to existing control voltage buses without additional transformers or converters.

Where Is It Used?

The Omron LY2 110/120VAC Socketed Relay is commonly specified for the following applications:

  • Control panels
  • Machine automation
  • Building management systems

Across these use cases, the consistent thread is a need for dependable switching over a large number of operations, often in environments where an unplanned fault would create significant disruption. The Omron LY2 110/120VAC is designed with exactly those conditions in mind.

The Omron LY2 110/120VAC is designed to be used with PF083A / PTF08A. Using a non-compatible socket model can compromise contact pressure and reduce overall service life, so always verify socket compatibility before ordering.

Installation Notes

Installation follows the same logical steps as any DIN rail component: de-energise the circuit first, secure the unit on the rail or with the appropriate socket, route cables with cross-sections matched to the contact current rating, and torque the terminal screws to specification. The Omron LY2 110/120VAC Socketed Relay does not require any specialised tooling — just careful preparation.

For ongoing maintenance, periodically inspect for contact discolouration, check terminal screws for loosening, and look for any signs of heat stress on the housing. Catching these early avoids the much larger cost of an unplanned production stop.

Why Choose the Omron LY2 110/120VAC?

The case for choosing the Omron LY2 110/120VAC Socketed Relay is not built on marketing alone. It rests on measurable factors: documented mechanical and electrical lifespan ratings, certifications that satisfy CE and UL requirements, and a global spare parts network that means you can source a replacement quickly when a unit eventually reaches end of life.

Frequently Asked Questions

What applications is the Omron LY2 110/120VAC designed for?

The Omron LY2 110/120VAC Socketed Relay is designed primarily for control panels, machine automation, building management systems. Its construction and contact ratings make it well suited to both continuous-duty and intermittent switching in these environments.

What coil voltage does the Omron LY2 110/120VAC use?

The Omron LY2 110/120VAC operates at a coil voltage of 110/120V AC. Always verify that your control circuit voltage matches before installation.

Does the Omron LY2 110/120VAC require a specific socket?
