D4B-2187N Travel Switch NEW

D4B-2187N OMRON Travel Switch NEW

OMRON Travel Switch D4B-2187N      

Product Description:

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).

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

Note:

1.The above values are initial values.

2.The above values may vary depending on the model. Consult your OMRON sales representative for details.

*1.The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for the operating conditions and environment beforehand.

*2.The durability is for an ambient temperature of 5 to 35°C and ambient humidity of 40% to 70%. For further conditions, consult your OMRON sales representative.

*3.The above values may vary depending on switching frequency, environmental condition, and relativity level, consult your OMRON sales representative.
