1 Proximity Sensors and Limit Switches The Heart of the Line for Robust and Reliable Control

2 Our Most Popular Proximity Sensors 872C WorldProx - General Purpose For less aggressive yet still demanding applications, the 872C WorldProx proximity sensor is the all-purpose answer. These solid-state devices feature a nickel-plated brass housing with a plastic face. They re economical, easy to use, reliable, flexible, and offered in a wide range of sizes and connection options. Standard length and short barrel styles IP67 (IEC 529) and NEMA 6P washdown ratings Protected against transient noise, short circuits, overload, false pulse and reverse polarity Output indicator with 360 visibility ToughLink cable resists abrasion, chemicals, fire and wicking A specially formulated epoxy provides a secondary seal and vibration resistance, resists impact, has low thermal expansion/contraction and helps prevent coil/face separation Grommet strain relief provides an interlock between housing, grommet and cable Stainless steel face and barrel resist impacts and abrasion Grommet and LED lens resist fluid or chemical penetration Leak-proof front end 871TM - Heavy Duty All Stainless Steel For harsh or extremely demanding environments, the 871TM All stainless steel proximity sensor really shines. With a high-strength stainless steel face and barrel, this tough, compact sensor resists impact, abrasion and corrosion to keep things moving where ordinary sensors grind to a halt. 871P VersaCube Long-range sensing, versatility and durability are all hallmarks of these special sensors. With sensing ranges of up to 40mm (unshielded models; 20mm for shielded models), they provide great application flexibility. A unique five-way mount makes them easier to mount and adjust than any comparable sensor. All in a rugged, durable housing. Long sensing range (40mm unshielded, 20mm shielded). Electrical protection against short circuit, overload,false pulse, transient noise, reverse polarity Same mounting hole pattern as similar cube style sensors and limit switch style models for easy retrofitting 5-position sensing face in one unit Rugged and durable housing Compact size Convenient, flexible mounting with a single screwdriver Mini and micro quick-disconnect models

4 Our Most Popular Limit Switches Patented 3-way shaft seal design offers superior fluid resistance Quad-ring seal between operating head and switch body Body gasket guards the switch cavity against entry of oil, dust, water and coolants Pull-and-turn mode change on lever style models allows easy selection between clockwise operation, counter-clockwise or both Castle lock head design Front-mount design allows mounting without exposing electrical connections Bulletin 802T Limit Switches 802Ts are ideal for applications in which heavy-duty pilot ratings, a small size, a high degree of versatility and a rugged NEMA Type 4 and 13 oil-tight construction are desired, including: Conveyor systems Transfer machines Automatic turret lathes Milling and boring machines Radial drills Bulletin 802M/MC Pre-Wired Bulletin 802M and 802MC compact pre-wired limit switches are factory-sealed to meet the demanding requirements for NEMA Type 4, 4X, 6P and IP67 enclosures. A large variety of operating heads and levers are available to suit a wide range of applications, especially where the switch may be subject to washdowns, streams of coolant, or occasionally submerged in fluids commonly found on machines or in industrial processes. Pre-wired and factory-sealed Can withstand submersion in 6 feet of water per NEMA 6P requirements Corrosion resistant (802MC models) Castle lock head design Diaphragm seal between operating head and switch body offers extra protection against contaminants when operating head is removed Highly resistant seals on cover, cable entry and wire strands prevent ingress of dust or fluids Field convertible head to operate clockwise, counter-clockwise or both Patented Allen-Bradley 3-way VITON shaft seal Stainless steel shaft and hardware (802MC models) Pre-wiring saves time and eliminates internal wiring ½ NPT conduit entry for easier installation Precision Compact Booted heads available for superior enclosure sealing Industry-standard mounting for easy application within existing designs Die-cast metal housings for increased ruggedness Triple-sealed construction for superior performance in washdown applications Multiple operator styles for maximum flexibility 3-meter cable as standard for one-size-fits-all flexibility Bulletin 802B Precision and Compact Limit Switches The 802B family of Allen-Bradley limit switches is designed to withstand today s tough industrial environments. Its compact but rugged enclosure makes the 802B ideal for mounting in areas too small for traditional NEMA-style limit switches. Each model features a die-cast housing for durability as well as industry-standard mounting dimensions and operating characteristics for optimal application flexibility. The precision line offers 5 unique head configurations that can be ordered in two mounting styles: side mount or flange mount. The compact style housing boasts a pre-wired 3-meter cable and triple-sealed construction, giving it NEMA 6 and IP67 enclosure ratings.
