PC board mounting method PC board pattern Contact terminal interval Coil terminal interval 8 7 6 5 15.00.2 .591.008 32.50.1 1.280.004 Press A side Claw for chassis fastening (2) Insert the relay all the way in, so it is securely in place. Hinge mechanism 1 2 3 4 2.54 .100 Chassis t = 0.6 to 2.2 .024 to .087 8-1.5 DIA. 8-.060 DIA. 2.54 .100 The terminal configuration is symmetrical on the left and right, so an arrow mark ; is stamped on the socket to prevent misinsertion. 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. Relay (3) Press the part indicated by A in the B direction, and fasten by placing the hook on the relay. Relay case cross-section B A (Before fastening) (Fastening complete) (4). When removing the relay, completely release the hooks on both sides and pull the relay out.
