To comply with explosion-proof switching requirements, the flame path within the switch housing is designed to contain and cool escaping hot gases and fumes that could cause an explosion outside of the switch. Regardless of where the equipment or machinery is designed, built, or installed, BX and BX2 Series products carry global agency coverage. Honeywell offers two versions of the BX series switch: the standard BX Series features an aluminum housing, while the BX2 series features a 316L stainless steel housing. The stainless steel housing adds additional resistance against corrosion in applications exposed to aggressive, caustic agents, as well as those often present in chemical processing plants, off-shore/near-shore sites, and other hazardous areas. Both products are weather sealed for outdoor use and designed for explosive gas/dust environments. All operating heads of the BX/BX2 Series are field adjustable at 90° increments. What makes our switches better? Around-the-world use in hazardous areas with international approvals: UL, CSA, ATEX (CE), IEC Ex, and NEPSI Ex (China) Industry-leading breadth of product offering that includes: BX (aluminum housing) and BX2 (stainless steel housing) limit switches for hazardous locations Top-of-the-line environmental sealing combined with Honeywell expertise for hazardous location package design provides the right product for the right application 303 stainless steel operating shaft on sintered bronze bearing for enhanced mechanical life and operational reliability Exclusive teller tab on levers ensures proper torque. When the tab cannot be moved, the lever is tight enough to prevent slippage Ready to work... anywhere in the world!

They are suitable for applications in demanding indoor and/or outdoor environments, where they may be subjected to shock or vibration from equipment, temperature extremes, dust, splashing water, coolant, and/or hose-directed water. International approvals for use around the world READY TO WORK - AROUND THE WORLD Agency coverage for hazardous locations provided through UL, CSA, ATEX (CE), IEC Ex, NEPSI Ex (China), and KOSHA (select listings - Korea). Industry-leading breadth of products WIDE VARIETY OF PRODUCT OFFERING Broad range of actuator styles are available for both aluminum and stainless steel head and body types. Many options for pin and roller plungers, rotary levers, or wobble (multidirectional) actuation facilitate installation. Single-pole or double-pole basic switch with gold or silver contacts provide reliable control of low energy or power-duty switching. WITHSTANDS MANY CAUSTIC ENVIRONMENTS Two rugged designs are available: aluminum or corrosion-resistant stainless steel head and body. Both designs are suitable for indoor and outdoor applications. A diaphragm seal between head and body provides an extra measure of protection. Switches remain functional when exposed to many severe environments and caustic chemicals. OPTIONAL SEALS Standard fluorosilicone seals are suitable for most applications, but optional fluorocarbon seals are available for harsh chemical or higher temperature environments. UNIQUE DESIGN FEATURES The head design is keyed for secure head-to-body retention with the head in any one of four positions 90° apart. Self-lifting pressure plate terminals saves wiring time. DESIGN FLEXIBILITY Honeywell offers a wide variety of non-sparking actuators, switch options, and head styles for design flexibility. Rotary actuated heads are field adjustable for CW actuation, CCW actuation, or both to reduce inventory. EASILY CONTROLS 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 OFF-SHORE AND ON-SHORE DRILLING Senses extend and retract position of drilling equipment PIPELINES Monitors pig position and resulting pipeline health PETROCHEMICAL AND CHEMICAL PLANTS Monitors control valves, doors, gates, and their position WATER TREATMENT PLANTS Senses control valve position PAINT BOOTHS Door interlocks for sliding or hinged gates or doors CONVEYORS (ABOVE-GROUND) Monitors belt tension, belt alignment PULP AND PAPER Senses product/material presence, roll size 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 for use in applications where the environment includes fire-resistant synthetic fluids, synthetic fluids, water-based fluids, and petroleum-based fluids. The additional FC seals also promote longer operating life for rotary-actuated BX/BX2 switches in applications where the temperatures are normally elevated. To order, insert the additional letter C in the appropriate places in the standard catalog listing, as shown below: BXA3K standard, side-rotary switch BXAC3K FC-sealed version of BXA3K BX2A3K standard, stainless steel side-rotary switch BX2AC3K Fluorocarbon-sealed version of BX2A3K MICRO SWITCH™ BX/BX2 SERIES OPERATING HEADS* SIDE ROTARY: Heads may be positioned in any one of four positions, 90° increments.

Seals are the same as the pin plunger. sensing.honeywell.com 9 BX | BX2 Series MICRO SWITCH™ BX/BX2 SERIES OPERATING HEADS SIDE PLUNGERS: Available with 4,83 mm [0.19 in] minimum overtravel. Side plungers are offered in pin plunger, adjustable pin plunger, and a roller plunger. All are momentary action. BXE/BX2E - Side pin plunger: A copper alloy plunger for actuating motion inline with the plunger travel. Actuating head may be rotated in any of four positions, 90° apart. A boot seal on the plunger and a gasket seal between the head and housing keep out coolant, dust, and chips. BXF/BX2F - Side roller plunger: A copper alloy roller plunger fits close quarters under cams and slides. The head may be rotated in any of four positions, 90° apart. The roller can be turned vertical or horizontal to the switch. Boot seal on plunger. WOBBLE LEVER ACTUATING HEADS: Heads come with either a Delrin® plastic rod or copper alloy cat whisker. Any movement of the lever (except pull) will actuate the switch. BXK - Plastic rod: Recommended where possible scratching or marring by the actuator is to be avoided. 10 sensing.honeywell.com BXJ - Cat whisker: Copper alloy actuator designed for low operating force applications. BXW - Adjustable side pin plunger: Has the same features of the side plain plunger plus the means to adjust the operating points of the switch from 41 mm to 47,4 mm [1.615 in to 1.865 in]. MICRO SWITCH™ Hazardous Area Limit Switches SIDE ROTARY • MICRO SWITCH™ BX/BX2 SERIES ORDER GUIDE/RECOMMENDED LISTINGS BXA /BX2A • Standard CW/CCW Momentary Housing Material Contacts Contact Material Conduit Listing (snap-action) 15°   1-2 3-4 3-4 1-2 75° 0° 10° Pretravel • 15° max.
