AUTOMOTIVE POWER RELAYS SMALL SIZE, LIGHT WEIGHT CA RELAYS RoHS compliant FEATURES Small size and light weight For space saving, the outside dimensions of the main body are reduced to be. mm (length). mm (width) mm (height) (... inch) and the weight is also reduced to be approx. g. oz (direct coupling Form A, Form B type) Low operating power (.W) type is available ( Form A, Form B) Since the terminal arrangement complies with JIS D B-M, commercial connectors are available for these types of relays. Superior inrush Despite its small size, A (max.. s) capacity has been achieved by using contacts that are good at withstanding inrush currents and because of an ingenious contacting mechanism. ( Form A and Form B) TYPICAL APPLICATIONS Motorcycles and automobiles Motorcycle cell motors, car air conditioners, halogen lamps, etc. Agricultural equipment Battery equipped devices such as conveyance vehicles ORDERING INFORMATION Contact arrangement a: Form A b: Form B : Protective construction Nil: Sealed type F: Dust cover type CA Nominal operating power Nil: Standard type (.
