Ultra-slim Safety door switch SG-A1

• Regardless of door types, do not use the safety switch as a door stop. Install a mechanical door stop at the end of the door to protect the safety switch against excessive force.
• Do not apply external force on the actuator while unlocking, otherwise the actuator may not be unlocked.
• Do not apply excessive shock to the safety switch when opening or closing the door. A shock to the safety switch exceeding 1,000 m/s² may cause damage to the safety switch.
• If the operating atmosphere is contaminated, use a protective cover to prevent the entry of foreign objects into the safety switch through the actuator entry slots. Entry of a considerable amount of foreign objects into the safety switch may affect the mechanism of the safety switch and cause a malfunction.
• Do not store the safety switches in a dusty, humid, or organic-gas atmosphere, or in an area subjected to direct sunlight.
• Use proprietary actuators only. When other actuators are used, the safety switch may be damaged.

• Cover the unused actuator entry slot using the slot plug supplied with the safety switch.

When using the safety switch on hinged doors, refer to the minimum radius of doors shown below. When using on doors with small minimum radius, use the angle adjustable actuator (SG-K13 / SG-K14).

Note :	The values indicated in the figures below assume that there is no mechanical interference between the actuator and the safety switch when the door is opened or closed. Because deviation or dislocation of hinged doors may occur in actual applications, make sure of the correct operation before installation.

When using the (SG-K13 / SG-K14) angle adjustable (vertical / horizontal) actuator

• When the door hinge is on the extension line of the actuator mounting surface: 70 mm 2.756 in
• When the door hinge is on the extension line of the safety switch surface: 50 mm 1.969 in

Actuator angle adjustment (vertical / horizontal)

• Using the angle adjustment screw (M3 hexagon-socket-head screw), the actuator angle can be adjusted.
  Adjustable angle: 0 to 20°
• The larger the adjusted angle of the actuator, the smaller the applicable radius of the door opening. After installing the actuator, open the door. Then adjust the actuator so that its edge can be inserted properly into the actuator entry slot of the safety switch.
• After adjusting the actuator angle, apply Loctite to the adjustment screw so that the screw will not move.

• Mount the safety switch on a fixed piece of machinery or guard and the actuator on a hinged door. Avoid mounting both the safety switch and actuator on a hinged door. Doing so may cause equipment failure. For more information about how to mount the devices, see the following diagram:

Safety switch: 1.0 to 1.5 N·m (Three M4 screws)*
Actuator: 1.0 to 1.5 N·m (Two M4 screws)*

*	The above recommended tightening torques of the mounting screws are the values confirmed with hexagon-socket-head bolts. When other screws are used and tightened to a smaller torque, make sure that the screws do not become loose after mounting.

• Mounting bolts must be provided by the users.
• To avoid unauthorized or unintended removal of the safety switch and the actuator, it is recommended that the safety switch and actuator are installed in a secure manner, for example using special screws or welding the screws.
• When installing the SG-K12A actuator, use the mounting plate (supplied with the actuator) on the hinged door, and mount tightly using two M4 screws.
  The mounting plate has orientation.
  Do not lose the mounting plate.
  Adequate performance cannot be obtained without the plate as the actuator may fall off the door.
  

• Do not fasten or loosen the gland at the bottom of the safety switch.
• When bending the cable during wiring, make sure that the cable radius is kept at 30 mm 1.181 in minimum.
• When wiring, make sure that water or oil does not enter the cable.
• The solenoid has polarity. Make sure of the correct polarity when wiring.
