CA AUTOMOTIVE POWER RELAYS SMALL SIZE, CA RELAYS LIGHT WEIGHT FEATURES TYPICAL APPLICATIONS Small size and light weight Motorcycles and automobiles For space saving, the outside dimensions Motorcycle cell motors, car air of the main body are reduced to be 21.5 conditioners, halogen lamps, etc. mm (length) 14.4 mm (width) 37 mm Agricultural equipment (height) (.846 .567 1.457 inch) and Battery equipped devices such as the weight is also reduced to be approx. conveyance vehicles 19 g .67 oz (direct coupling 1 Form A, 1 Form B type) Low operating power (1.4W) type is available (1 Form A, 1 Form B) Since the terminal arrangement complies with JIS D5011 B4-M1, commercial connectors are available for these types of relays. Superior inrush characteristics Despite its small size, 120A (max. 0.1 s) capacity has been achieved by using contacts that are good at withstanding inrush currents and because of an ingenious contacting mechanism.

This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load. *2. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value.
