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
;
mounting side (side opposite from pat-
tern) of the PC board. In this case, the ter-
minal configuration becomes the terminal
nos. noted near the drilling holes.

Press
If the chassis hole is punched with a
press, set so the release R on the front
side (A side).
The range for chassis thickness is 0.6 to
2.2 mm .
024 to .087 inch
.
3. Relay mounting and removal
(1) Align the directions of the relay and socket.

(2) Insert the relay all the way in, so it is secure-
ly in place.
(3) Press the part indicated by A in the B direc-
tion, and fasten by placing the hook on the re-
lay.
(4). When removing the relay, completely re-
lease the hooks on both sides and pull the relay
out.
