MICRO SWITCH Heavy-Duty Limit Switch 002345 HDLS Series Issue 10 Datasheet FEATURES NEMA 1, 3, 4, 4X, 6, 6P, 12, 13 and IP65/66/67 environmental sealing NEMA/IP sealing features twin shaft seals for an extra measure of protection Rugged, corrosion-resistant zinc head and body are phosphate treated and epoxy coated Diaphragm seal between head and body provides an extra measure of protection Multiple connectivity options for international applications Fluorosilicone seals available for low temperature applications, and fluorocarbon seals available for chemically harsh environments and higher temperature applications Secure head-to-body retention with the head in any one of four positions 90 apart DESCRIPTION Self-lifting pressure plate terminals saves wiring time Honeywells MICRO SWITCH heavy-duty limit switches Wide variety of actuators, switch options, and head styles modular construction allows for a wide variety of actuator Rotary actuated heads are field adjustable for CW actuation, styles, operating heads, and electrical circuitry options. The CCW actuation, or both plug-in versions greatly reduce downtime on production lines Silver or gold-plated contacts with high actuation rates as replacement of the switch is Plug-in and non plug-in bodies have identical operating accomplished in seconds. The base receptacle contains all the characteristics and are dimensionally interchangeable wiring and conduit connection while the switching component with operating head easily assembles to the base and is POTENTIAL APPLICATIONS attached with two screws. Machine tools They are ideal for many applications with demanding indoor Automotive machine tools and/or outdoor environments, where they may be subjected Material handling to shock or vibration from equipment, temperature extremes, Outdoor electromechanical structures dust, splashing water, coolant, and/or hose-directed water.
