Limit Switches XCKML—General Specifications and Complete Devices Refer to Catalog 9006CT0101 XCKML is a general duty limit switch, larger than the XCKL, for applications such as machine tools, material handling, and other applications where electrical redundancy and contact state signaling are required. Key features include: ● 2 normally closed, direct opening and two normally open, snap action contacts available in 4 head styles ● Direct opening contacts standard: snap action 2-pole (isolated N.O. + N.C.) or slow-make-slow-break 2-pole (isolated N.O. + N.C.) ● 4 position indexing rotary head (field convertible) ● Captive screws and gaskets ● Captive saddle clamp terminals ● Feature Fingersafe® contact block ● Lever operated—positive lever to shaft positioning to ensure the direct opening feature. Direct opening contacts meet IEC 947-5-1 requirements for positive opening contacts. ● Plunger operated: top rod, top roller ● Metal type, IP66 ● Complete switches with 3 cable entries ● Tapped for 13 mm cable gland, DE9RA1212 adapter to 1/2" NPT included UL Listed CSA Certified, IEC, VDE, CENELEC and other international approvals, CE Table 21.81: Characteristics Conforming to standards Products IEC 947-5-1, EN 60 947-5-1 Machine assemblies IEC 204-1, EN 60 204-1, NF C 79-130 Protective treatment Standard version: “TC” Ambient air temperature Operation: -25 to +70o C Resistance to vibration 25 gn (10 to 500 Hz) conforming to IEC 68-2-6 to shocks 50 gn conforming to IEC 68-2-27 Electric shock protection Class I conforming to IEC 536 and NF C 20-030 Degree of protection IP66 conforming to IEC 529; IP65 conforming to NF C 20-010 Minimum force of torque for tripping 15 N 12 N 8 N 0.2 N.m for positive opening 60 N 50 N 50 N 0.5 N.m Maximum actuation speed 0.5 m/s 0.5 m/s 1.5 m/s 1.5 m/s Switch actuation On end By 30o cam Repeat accuracy ± 0.1 mm on the tripping points Rated operational characteristics ~ AC-15; A300 or Ue = 240 V, le = 3 A (for make and break ratings see XCKL page 21-27)DC-13; Q300 or Ue—250 V, le = 0.27 A conforming to IEC 947-5-1 Appendix A, EN 60 947-5-1 Rated insulation voltage Ui = 500 V degree of pollution 3 conforming to IEC 947-1 Rated impulse withstand voltage U imp = 6 kV conforming to IEC 947-1, IEC 664 Positive operation N.C. contacts with direct opening operation conforming to IEC 947-5-1 Appendix K, EN 60 947-5-1 Short-circuit protection 10 A cartridge fuse gG (gl) Cable entry 3 tapped entries for 13 mm cable glands conforming to NFC 68-300 (DIN Pg 13.5).
