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.

G1/2 D4N-6D87 D4N-8D87 Note: 1. It is recommended that M20 be used for Switches to be exported to Europe and 1/2-14NPT be used for Switches to be exported to North American countries. WARNING 2. Mechanically speaking, these models are basic limit switches. - Page 7 Note: 1. The above values are initial values. 2. Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity. Doing so may result in rough- ening of the contact surface and contact reliability may be lost.
- Page 8 Head Grooves which engage the lever are cut in the lever and The direction of the switch head can be varied to any of rotary shaft to prevent the lever from slipping against the the four directions. (Roller plunger models can be rotary shaft.
- Page 9 Note: 1. Terminals are numbered according to EN50013 and the contact forms are according to IEC947-5-1. 2. MBB (Make Before Break) contacts have an overlapping structure, so that before the normally closed contact (NC) opens, the normally open contact (NO) closes.

Be sure to mount it cor- rectly. : M screws are recommended to comply with European standards. Therefore, the M20 type is recommended as a substitute when the PG13.5 conduit-type is not available in a D4N model.
