2 N.O. and 2 N.C. Direct Opening Snap Action Contacts Rated Power Conforms to IEC 947-5-1 Duty Categories AC15 and DC13.
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(R) 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 12" NPT included UL Listed CSA Certified, IEC, VDE, CENELEC and other international approvals, CE Characteristics
