MICRO SWITCH™ Hazardous Area Switches LSX Series Datasheet MICRO SWITCH™ LSX Series Hazardous Area Limit Switches MICRO SWITCH™ LSX hazardous area switches are designed for use in adverse environments. They are approved for use in hazardous locations and NEMA classified atmospheres because their rugged housings have integral flame paths. These flame paths force internal expanding gases to cool below external atmosphere ignition temperatures before they leave the housing. The LSX also features tracking interchangeability with MICRO SWITCH™ BX Series Hazardous Area switches. An optional mounting plate provides the same tracking and mounting as the standard HDLS Series (heavy-duty limit switch). The majority of HDLS operating heads and circuitry options are available for the LSX Series. The rotary actuated LSX series products are designed for use with levers that have non-sparking actuators due to the potentially hazardous environment. The other styles of LSX Series switches which are the plunger actuated and wobble actuated products incorporate an integral nonsparking actuator. What makes our switches better? Industry-leading breadth of product Weather sealed to NEMA 1, 3, 4, 6, 13 Explosion proof to NEMA 7 (Class 1, Division 1 & 2, Groups B, C, D), NEMA 9 (Class 2, Division 1 & 2, Groups E, F, G) Extensive variety of actuation heads and multiple non-sparking actuators All metal drive train that offers consistent operating characteristics through a broad temperature range. Also lasts longer (without need for frequent adjustment) than drive trains with plastic parts SAFE • RELIABLE EXPLOSION PROOF • WEATHER SEALED 2 sensing.honeywell.com Features and Benefits DESIGN FLEXIBILITY MICRO SWITCH™ LSX limit switches’ field adjustability (CW-CCW operation, rotatable operating head) assists in matching the switch to the application. Available with momentary, maintained, sequential, or center neutral action. All-metal drive train for consistent operation UNIQUE DESIGN FEATURES The head design is keyed for more secure head-to-body retention with the head indexable in any one of four positions 90° apart. Captive mounting screws in the heads help prevent the loss of screws during replacement or repositioning of the head. Self-lifting pressure plate terminals save wiring time. Industry-leading breadth of products WITHSTANDS MANY CAUSTIC ENVIRONMENTS A die-cast zinc head and aluminum body make the LSX suitable for indoor and outdoor applications. A diaphragm seal between the head and body is designed to provide an extra measure of protection. Switches remain functional when exposed to many severe environments and caustic chemicals. OPTIONAL SEALS Standard seals are suitable for most applications, but optional fluorocarbon or fluorosilicone seals are available for many harsh chemical, high or low temperature environments. DESIGNED TO CONTROL LOW-VOLTAGE DC APPLICATIONS Hazardous area switches are available with a choice of silver or gold-plated contacts to handle a variety of electrical load requirements from low energy to power-duty control. sensing.honeywell.com 3 Potential Applications GRAIN ELEVATORS Monitors plugged grain conveyors, slide gate position, diverter valves, and leg positions CONTROL VALVES AND ACTUATORS Senses the “on” or “off” position of the valve ON-SHORE DRILLING Detects end of travel positions for extend and retract operations of drilling equipment PIPELINES Monitors pig position and resulting pipeline health PETROCHEMICAL AND CHEMICAL PLANTS Monitors the position of control valves, doors, and gates WATER TREATMENT PLANTS Detects control valve position PAINT BOOTHS Door interlocks for sliding or hinged gates or doors HAZARDOUS WASTE HANDLING Often used as a valve position monitor 4 sensing.honeywell.com MICRO SWITCH™ Hazardous Area Limit Switches Figure 1.

Rotary types have an extra FC seal on the operating shaft, while plunger versions have FC boot seals. They are designed for use in applications where the environment includes fire-resistant synthetic fluids. In addition, the FC-sealed switches may be used with such industrial fluids as Cellulube, Fyrquell, Houghto-Safe, Pydraul, and other special cutting and hydraulic fluids. The additional FC seals also promote extended operating life for rotary-actuated LSX switches in applications where the temperatures are normally -12 °C to 121 °C [10 °F to 250 °F].
