DIMENSIONS
Precautions for use (socket)
1. PC board mounting method
PC board pattern
The terminal configuration is symmetrical
on the left and right, so an arrow mark ;
is stamped on the socket to prevent mis-
insertion. We recommend printing the
same arrow mark ; on the component
mounting side (side opposite from
pattern) of the PC board. In this case, the
terminal configuration becomes the
terminal nos. noted near the drilling
holes.

6. Contact reliability
(2) Insert the relay all the way in, so it is
securely in place.
(3) Press the part indicated by A in the B
direction, and fasten by placing the hook on the
relay.
(4). When removing the relay, completely
release the hooks on both sides and pull the
relay out.
