AUTOMOTIVE POWER
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)

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.
CA-RELAYS
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.
