• 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.
• Small size
The smallest double make type relay
12.0(W)×15.5(L)×13.9(H) mm
.472(W)×.610(L)×.547(H) inch
• Pattern design simplification
Simplified pattern design is possible
because, while double make construction
is employed, the external COM terminal
is single.
