• Pattern design simplification
Simplified pattern design is possible 
because, while double make construction 
is employed, the external COM terminal 
is single.

• Standard terminal pitch employed
The terminal array used is identical to 
that used in JJM relays(1c type).

• Plastic sealed type
Plastically sealed for automotive 
cleaning.

#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.
