MINI-ISO
CB RELAYS
AUTOMOTIVE RELAY
FEATURES TYPICAL APPLICATIONS
This relay has an Mini-ISO Automobiles
(International Organization for Headlights, Cell motors, Air conditioners,
Standardization) terminal ABS, EPS, etc.
arrangement. Construction equipment
Relay is compact and high capacity Agricultural equipment, Conveyor,
(40 A). etc.
Compact form factor realized with space
saving 22 26 mm .866 1.024 inch
small base area thanks to integrated
bobbin and base construction. Features
high switching capacity of 40 A
Features high thermal resistance of
125 C 257F (heat resistant type).
Heat resistant type is available that can
withstand use near engines. (40 A
switching capacity)
Built-in resistor type is also
available.
