1 Safety Interlock Switches D4B- N D4BN Safety Limit Switch Snap-action contact with certified direct operation. mechanism (NC contacts only) added to enable 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 IP7, UL: NEMA, 4, 4X, P, and 1). Wide standard operating temperature range: 4 to C. s with gold-plated contacts to enable handling micros. Certified standards: UL, CSA, EN (TÜV), and CCC.
