WL-3A100

Safety Limit SwitchD4B-#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.Model Number StructureModel Number LegendD4B-####N12 31.Conduit1: PG13.5 (1-conduit)2: G1/2 (PF1/2) (1-conduit)3: 1/2-14NPT (1-conduit)4: M205: PG13.5 (3-conduit)6: G1/2 (PF1/2) (3-conduit)7: 1/2-14NPT (3-conduit)8: M20 (3-conduit)2.Built-in Switch1: 1NC/1NO (snap-action)3: 1NC/1NO (slow-action) gold-plated contacts5: 1NC/1NO (slow-action) (see note) A:2NC (slow-action)B:2NC (slow-action) gold-plated contactsNote: Excluding D4B-##81N and D4B-##87N models.3.Actuator00: Switch box (without head)11: Roller lever (standard)16: Adjustable roller lever17: Adjustable rod lever1R:Roller lever(conventional D4B-compatible)70: Top plunger71: Top roller plunger81: Coil spring87: Plastic rodD4B-@NG-243
