CA Series Relays

Panasonic's CA Series Relay is a small-sized and lightweight Automotive Relay available in either SPST-NO (1FormA), SPST-NC (1FormB), or SPDT (1FormC) contact arrangements. For space-saving, the outside dimensions of the main body are reduced to 21.5mm (length) x 14.4mm (width) x 37mm (height).

In addition, since the terminal arrangement complies with JIS D5011 B4-M1, commercial connectors are available for easy mounting. Despite the small size of this Relay, it can handle a large inrush current up to 120A for 100ms.

Features and Benefits of CA Series Relays
