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 pat-
tern) of the PC board. In this case, the ter-
minal configuration becomes the terminal
nos. noted near the drilling holes.

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.
