Safety Limit Switch
D4B-#N
• Snap-action or slow-action contact for accurate switching with safe operation via a direct opening mechanism with metal deposition between mating con- tacts.
• Two sets of contacts: one (NC) for safe- ty category circuit and the other (NO) for control circuit.
• Contacts opened by direct opening mechanism (NC contacts only), thus preventing faulty operation due to fac- tors such as metal deposition.
• Wide standard operating temperature range:
–40°C to 80°C (standard type).
• Safety of lever settings ensured using a mechanism that engages a gear be- tween the operating position indicator plate and the lever.
• Equipped with a mechanism that indi- cates the applicable operating zone, as well as push-button switching to control left and right motion.
• Conforms to EN (TÜV) standards cor- responding to the CE marking.
• 3-conduit switches are available.
• Metric conduit types available.
