ORDERING INFORMATION
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 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) TYPICAL APPLICATIONS
- Motorcycles and automobiles Motorcycle cell motors, car air conditioners, halogen lamps, etc.
- Agricultural equipment
- Battery equipped devices such as conveyance vehicles Contact arrangement 1a: 1b:
