Accessories (Order Separately)
Terminal Covers (Sold Separately)
The Terminal Covers can be attached to Z, A, X, and DZ Switches.
The Terminal Cover is secured with mounting screws and protects the casing and terminal wires from dust, vibration, or fingers, thus preventing terminal short-circuiting, ground faults, wire disconnection or improper connection, and electric shock accidents.
Terminal Covers made of phenol resin have five or six thin wall sections. These sections can be torn open for providing holes for lead cables at desired points.
A terminal cover can’t be used in the case of using an actuator sold separately.
Note: Use a Terminal Cover for screw terminals fir DZ-series Switches w

Terminals
Screw Terminals (-B)
Solder Terminal (-A)
(“-A” is not included in the model numbers.)
Note: 1. Appropriate terminal screw tightening torque: 0.78 to 1.18 Nm.
2. Unless otherwise specified, a tolerance of ±0.4 mm applies to all dimensions.
Mounting Holes
Use M4 mounting screws with plane washers or spring washers to securely mount the Switch. Tighten the screws to a torque of 1.18 to 1.47 Nm.
The Switch can be panel mounted, provided that the hexagonal nut of the actuator is tightened to a torque of 2.94 to 4.9 Nm.
The models, illustrations, and graphics are for screw-terminal models. (The dimensions for models that are omitted here are the same as for pin-plunger models.)
