Miniature Safety Limit Switch

D4N

Safety Limit Switches

compatible to the Popular

D4D, Providing a Full

Lineup Conforming to In-

ternational Standards

• Lineup includes three contact models

with 2NC/1NO and 3NC in addition to

the 1NC/1NO, and 2NC contact mod-

els. Models with MBB contacts are

available too.

• M12-connector models are available,

saving on labor and simplifying mainte-

nance.

• Standardized gold-clad contacts pro-

vide 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.

Be sure to read the Safety Precautions on

page G-237.

Note: Contact your sales representative for details on models with safety standard certification.

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.
