MICRO SWITCH Heavy-Duty Limit Switch (Stainless Steel) 002426 HDLS LS2 Series Issue 1 Datasheet FEATURES 316 Series stainless steel actuating heads and body with stainless steel screws Designed to IP 65/66/67 and NEMA 1, 3, 3R, 4, 4X, 6, 6P, 12, and 13 Diaphragm seal between head and body provides an extra degree of sealing Fluorocarbon seals standard for chemically harsh environments and/or higher temperature applications (121 C/250 F) Optional fluorosilicone seals for low temperature (-40 C/-40 F) applications Available with 1NC/1NO or 2NC/2NO double break contacts. Same polarity for each pole (Za) Side rotary head with center neutral or sequential switch DESCRIPTION design available When the application requires an industrial grade limit switch Actuator heads can be field rotated to any of four positions where wet, dust, or corrosive environments may be present, 90 apart Honeywell offers the LS2 Series of stainless steel limit Side rotary heads are factory adjusted for CW and CCW switches. The limit switch body and actuating heads are cast actuation of the switch. Heads can be field adjusted for CW from 316 stainless steel. These limit switches are available with only or CCW only to actuate the switch a wide variety of actuating heads with a one-pole or two-pole CCC, CE, CSA, and UL certifications for global acceptance snap-action double-break contact block. A threaded conduit is integral to the switch body with terminal screws for each wiring POTENTIAL APPLICATIONS point on the contact block. Honeywell can provide the switches Food processing plants factory wired for reduced installation. The limit switches Petrochemical plants can also be factory wired with the limit switch body epoxy Power generating plants encapsulated, minimizing any dust or liquid migrating to the Pulp and paper mills switch contacts. The limit switches can be front mounted with Shipboard and dockside locations two through holes or rear mounted with two integral threaded Transportation hubs and facilities holes from the back side. Water treatment and wastewater treatment facilities As with the other HDLS Series of limit switches, the LS2 Series have UL, CSA, CE, and CCC certifications for global VALUE TO CUSTOMERS acceptance. Harsh-duty stainless steel switch withstands many tough environments including dust, dirt, grime, heat, and washdown areas DIFFERENTIATION Variety of actuator heads and switch options Stainless steel housing designed for corrosive and adverse Threaded conduit or factory wired environments Silver contacts or optional gold-plated contacts All-metal drive chain for consistent operating characteristics Made in the USA Three different electrical connectivity options threaded conduit, factory wired, or factory wired with epoxy PORTFOLIO encapsulated body The heavy-duty LS2 Series stainless steel limit switches are a Side rotary head incorporates stainless steel shaft with portion of Honeywells heavy duty HDLS Series limit switches bronze bearing for increased mechanical life of up to 50 which also include the HDLS Series and the factory sealed million operations HDLS Series. Honeywell has a comprehensive line of general Wide selection of stainless steel levers to compliment the purpose limit switches, compact precision limit switches, side rotary limit switch miniature limit switches, and specialty limit switches.
