RELAYS — SMALL SIZE, LIGHT WEIGHT AND COMPLETELY WATER TIGHT
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)
- Water tightness Since the relays comply with the water tightness standards, JIS D 0203, water and dust will not enter the relay even if it is mounted in the engine area. 3. Low operaing power (1.4W) type is available (1 Form A, 1 Form B) 4. Since the terminal arrangement complies with JIS D5011 B4-M1, com- mercial connectors are available for these types of relays.
