General Purpose Relays

The contacts of this type of relay will turn on immediately when the induction coil is energized and will stop working (turn off) when the power is stopped. That is, if we want the contacts to turn on all the time, we must also supply power to the induction coil all the time.

Miniature Power Relays – MY-GS


  • Added lock lever for easier circuit inspection
  • Wiring work reduced by 60% when used with PYF-PU Push-In Plus socket (Actual measurement by OMRON)
  • Relays with AC and DC coils have different colored operation indicators (LEDs)
  • Printing on the tape indicates the coil operation specifications
  • Mechanical operation indicator is a standard feature on all models


Bi-power Relays – LY


  • Wiring can be shortened by up to 60%* compared to conventional screw terminal connectors by using a positive terminal connector (PTF-[]-PU) that features light insertion force and strong pullout force to achieve less wiring.
  • Standard models include models that comply with UL and CSA safety standards and the Electrical and Materials Safety Act.
  • Install arc barriers for arc interruption.
  • Withstands voltages up to 2000 V
  • A new generation of integrated diodes and integrated CR circuits have joined the series.
  • The product line also has models that comply with LR and VDE safety standards* when both push-in plus terminals and screw terminal block are combined with plug-in terminal type (Actual measurement by OMRON as of November 2015)


General-purpose Relay – G2R-[]-S (S)


  • Reduces wiring by 60% when combined with P2RF-[]-PU Push-In Plus socket (Actual measurement from OMRON)
