• 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.

 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.

• Power windows
• Auto door lock
• Electrically powered sun roof
• Electrically powered mirror
• Cornerring lamp, etc.

#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.
