CA1A-DC12V-N

CA AUTOMOTIVE POWER RELAYS — SMALL SIZE, LIGHT WEIGHT CA RELAYS FEATURES TYPICAL APPLICATIONS • Small size and light weight For space saving, the outside dimensions of the main body are reduced to be 21.5 mm (length)  14.4 mm (width)  37 mm (height) (.846  .567  1.457 inch) and the weight is also reduced to be approx. 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. (1 Form A and 1 Form B) • Motorcycles and automobiles Motorcycle cell motors, car air conditioners, halogen lamps, etc. • Agricultural equipment • Battery equipped devices such as conveyance vehicles ORDERING INFORMATION CA Contact arrangement 1a: 1 Form A 1b: 1 Form B 1: 1 Form C Protective construction Nil: Sealed type F: Dust cover type Nominal operating power Nil: Standard type (1.8 W) S: Low operating power type (1.4 W) (1 Form A, 1 Form B) Protective element Nil: None (Standard type) R: With resistor inside Coil voltage (DC) 12 V, 24 V (1 Form C only) Mounting method A: Rubber bracket A type (1 Form A, 1 Form B) N: Screw mounting type C: Direct coupling type Classification by type Nil: 1 Form C 5: 1 Form A or 1 Form B ds_61201_en_ca: 010113J 1 CA TYPES Standard type Contact arrangement Coil voltage Mounting type Rubber bracket A 1 Form A 1 Form B 12 V DC 12 V DC 12 V DC 1 Form C 24 V DC Low operating power type Sealed type Dust cover type Sealed type Part No. Part No. Part No. Dust cover type Part No. CA1a-12V-A-5 CA1aF-12V-A-5 CA1aS-12V-A-5 CA1aFS-12V-A-5 Screw-mounting CA1a-12V-N-5 CA1aF-12V-N-5 CA1aS-12V-N-5 CA1aFS-12V-N-5 Direct coupling CA1a-12V-C-5 CA1aF-12V-C-5 CA1aS-12V-C-5 CA1aFS-12V-C-5 Rubber bracket A CA1b-12V-A-5 CA1bF-12V-A-5 CA1bS-12V-A-5 CA1bFS-12V-A-5 Screw-mounting CA1b-12V-N-5 CA1bF-12V-N-5 CA1bS-12V-N-5 CA1bFS-12V-N-5 Direct coupling CA1bFS-12V-C-5 CA1b-12V-C-5 CA1bF-12V-C-5 CA1bS-12V-C-5 Screw-mounting CA1-12V-N – – – Direct coupling CA1-12V-C – – – Screw-mounting CA1-24V-N – – – Direct coupling CA1-24V-C – – – Standard packing: Carton: 20 pcs.
