Omron Electronic Components LLC released the G2RL-1ATP series of power PCB relays featuring 0.25-inch external, quick-connect-contact load terminals. The use of quick-connect terminals allows the load current to be directly routed through the relay's contacts, eliminating the need for large PCB traces.

Routing the load current in this manner reduces heat generated on the PCB, helping designers to meet agency requirements most notably when switching heating elements in appliance applications. The G2RL-1ATP is in a 12.6-by-32.5-by15.9mm flux-protected thru-hole package with a dielectric strength of 5,000Vac (coil-contact) and 1,000Vac (between open contacts).

The coil operates with 400mW and incorporates a class-F coil-insulation system. These relays are UL, CSA and VDE approved, meet the EC required tracking resistance of CTI>250 -and deliver a minimum of 50,000 operations while switching 16A at 250Vac (resistive) in an ambient temperature of 105C. Their impulse-withstand voltage is 10kV for 1.2 x 50?s, between coil and contacts.

The G2RL-1ATP series of power PCB relays is now available. Pricing starts at $1.99 for 5,000-piece quantities.
