FEATURES
• Compact (half-size).
The base area is approximately half the
size of conventional (JS-M) relays. The
controller unit can be made more
compact.
Base area has been reduced by one half
• Perfect for automobile electrical
systems.
Over 2 × 105 openings possible with a 14
V DC motor load, an inrush current of 25
A, and steady state current of 5 A.
(N.O. side)
• Standard terminal pitch employed
The terminal array used is identical to
that used in small automotive relays.
• Plastic sealed type.
Plastically sealed for automatic cleaning.
• Line-up of 1 Form A and 1 Form C.
TYPICAL APPLICATIONS
• Power windows
• Auto door lock
• Electrically powered sun roof
• Electrically powered mirror
• Cornerring lamp, etc.

2. Specifications
Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Please refer to “Usage ambient
condition” in CAUTIONS FOR USE OF AUTOMOTIVE RELAYS.
Please inquire if you will be using the relay in a high temperature atmosphere (110°C 230°F).
*3. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.
