New Product News DC Power Relays G9EN-1 DC Power Relays that Enable DC Load Interruption at High Voltage and Current Enable downsizing, weight saving, and non-polarization in the main contact circuit (contact terminal) by using proprietary design of the contact block. Contributes to improvements in the ease of wiring and mounting, and error-proofing against faulty wiring. Class smallest: H50 mm W28 mm L40 mm Class lightest: approx. 140 g. Accomplished half-size reduction in volume and weight when compared to Omron s same class product (400 VDC, 60 A). * *Omrons internal investigation of August 2012 RoHS Compliant Refer to the Precautions on page 4.
