Miniature Safety Limit Switch D4N 1

Miniature Safety Limit Switch

D4N

Safety Limit Switches compatible to the

Popular D4D, Providing a Full Lineup

Conforming to International Standards

• Lineup includes three contact models with 2NC/1NO and 3NC

in addition to the 1NC/1NO, and 2NC contact models. Models

with MBB contacts are available too.

• M12-connector models are available, saving on labor and sim-

plifying maintenance.

• Standardized gold-clad contacts provide high contact reliability.

Can be used with both standard loads and microloads.

• Free of lead, cadmium, and hexavalent chrome, reducing the

burden on the environment.

• Conforms to EN115 and EN81-1.

• Lineup includes both slow-action and snap-action models with

Zb contacts.

!Caution

Be sure to read the Safety Precautions on page 19.

Note: Contact your sales representative for details on models with

safety standard certification.

Structure, Names, and Functions ■ Structure Safety-oriented Lever Setting (Form-lock construction) Grooves which engage the lever are cut in the lever and rotary shaft to prevent the lever from slipping against the rotary shaft. There are resin-lever and metal-lever types. Head The direction of the switch head can be varied to any of the four directions. (Roller plunger models can be mounted in either of two directions at a 90˚ angle.) Conduit Opening A wide variety of conduits is available.

Safety Precautions Refer to OMRON SAFETY COMPONENTS SERIES (Y106) for common precautions for Switches and Safety Limit Switches. CAUTION Mounting Method Mounting Screw Tightening Torque Do not use metal connectors or metal conduits with this Switch. Doing so may occasionally result in electric shock. Tighten each of the screws to the specified torque. Loose screws may result in malfunction of the Switch within a short time. ■ Precautions for Safe Use 1 Terminal screw 0.6 to 0.

• Use a cable with a suitable diameter for the connector. • Attach and tighten a conduit cap to the unused conduit opening when wiring. Tighten the conduit cap to the specified torque. The conduit cap is provided with the Switch (2-conduit types). Changing the Lever The lever mounting screws can be used to set the lever position to any position in a 360° angle at 7.5° increments. Grooves are incised on the lever and rotary shaft that engage to prevent the lever from slipping against the rotary shaft.
