Safety-door Switch D4NS A-13
D4NS
Safety Door Switches
Head Direction
• The rotation of the Switch head may be adjusted to any of the four
directions by loosening the head clamping screws at the four
corners of the head. Make sure that no foreign materials enter
through the head.
• When changing the direction of the head, do so while the Operation
Key is inserted.
Securing the Door
When the door is closed (with the Operation Key inserted), it may be
pulled beyond the set zone because of, for example, the door’s
weight, or the door cushion rubber. Also, if a load is applied to the
Operation Key, the door may fail to unlock properly. Use hooks to
ensure that the door stays within the set zone.
Wiring
• When connecting with insulation tubes and M3.5 crimp terminals,
connect the terminals as shown in the following figure and wire
without overriding to the case and the cover. Adequate conductor
size is AWG 20 to AWG18 (0.5 to 0.75 mm
2
).
Prepare lead wires using the lengths given in the following
diagrams. If lead wires are too long, they will press against the
cover causing the cover to not close properly.
• Do not push the crimp terminal and the likes into the opening
between the parts to prevent the case from being broken and
deformed.
• Use terminals having the thickness of 0.5 mm or less to avoid the
contact between the terminal and the Switch case inside.
The terminals listed below have thickness of 0.5 mm or less.
J.S.T is a Japanese manufacturer.
Contact Arrangement
• The following show a safety contact and an auxiliary contact for 3
contacts and 2 contacts types.
• Refer to the Connector Catalog for corresponding Socket pin
numbers and lead wire colors.
Socket Tightening (Models with Connectors)
• Turn the tightening screws on the Socket by hand and tighten them
until the gap between the Socket and Plug essentially disappears.
• Make sure, however, that the Socket’s connector is tightened
securely, otherwise the rated degree of protection (IP67) of the
D4NS may not be maintained. Furthermore, the Socket connector
may be loosened by vibration.
Conduit Opening
• When using 1/2-14NPT conduits, apply sealing tape between the
connector and conduit opening to maintain the degree of protection
(IP67) of the Switch.
• Use cables with suitable diameters for the connector being used.
• When wiring, place the enclosed cap screw on unused conduit
openings (for 2-Conduit Switches) and tighten them to the suitable
tightening torque.
