Safety Limit Switch

D4B-@N

CSM_D4B-_N_DS_E_5_1

Snap-action contact with certified direct

opening operation certification .

Maintenance, seal, and resistance to

shock increased and direct opening

mechanism added.

Three-conduit switches and 2NC

switches are also available.

• Direct opening mechanism (NC contacts only) added to

enable opening contacts when faults occur, such as fused

contacts.

• Safety of lever settings ensured using a mechanism that

engages a gear between the operating position indicator plate

and the lever.

• Equipped with a mechanism that indicates the applicable

operating zone, as well as push-button switching to control left

and right motion.

• Head seal structure strengthened to improve seal properties

(TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13).

• Wide standard operating temperature range:

–40 to 80°C (standard type).

• Models with gold-plated contacts added to the series to

enable handling microloads.

• Certified standards: UL, CSA, EN (TÜV), and CCC.

Be sure to read the

“Safety Precautions”

on page 14

and the

“Precautions for All Safety Limit Switches”

Note:

Contact your sales representative for details on models

with safety standard certification.
