CM Series Relays

Panasonic's CM Series is an automotive relay with a small size form factor of 20mm x 15mm x 22mm available in both PCB and Plug-in Type with Micro-ISO (International Organization for Standardization) terminals. This relay has both SPST (1FormA) and SPDT (1FormC) contact arrangements available. The CM Series has a high switching capacity of 35A @ 14VDC for the Normally Open contact and 20A @ 14VDC for the Normally Closed contact. Both sealed and flux-resistant construction types are available. A built-in resistor option is available for coil protection against EMF. Both 12V and 24V DC coils are available in this series.
