AUTOMOTIVE POWER
CA-RELAYS ^{RELAYS — SMALL SIZE,}
LIGHT WEIGHT AND
COMPLETELY WATER TIGHT
FEATURES
1. 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)
2. 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.
