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.
2. Chassis cutout
Chassis cutting dimensions
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
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.
