Limit Switches

70 k pdf Back to Product Directory View catalog pages In this globally competitive economy, one of our major goals is to help make you more competitive. That's why we have developed one of the broadest and most durable lines of limit switches in the industry. A limit switch is an electro-mechanical device that consists of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection. Limit switches are used in a variety of applications and environments because of their ruggedness, simple visible operation, ease of installation and reliability of operation.

Bulletin 802T Limit Switches 802Ts are ideal for applications in which heavy-duty pilot ratings, a high degree of versatility and rugged NEMA Type 4 and 13 oil-tight (6P on select rotary shaft models) enclosures are desired, including: Conveyor systems Transfer machines Automatic turret lathes Milling and boring machines Radial drills             Bulletin 802M/MC Pre-Wired Limit Switches 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 under conditions exceeding NEMA 6P requirements Corrosion resistant (802MC models) Bulletin 802B Compact, Precision and Small Precision 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 compact style housing boasts a pre-wired 3-meter cable or connector version and triple-sealed construction, giving it NEMA 6 and IP67 enclosure ratings. The precision line offers 5 unique head configurations that can be ordered in two mounting styles: side mount or flange mount. The small precision family offers additional features in an even smaller package, providing a washdown-rated housing with 12 different head configurations. Bulletin 440P International Style Limit Switches The 440P limit switch family offers a full range of international style solutions for both safety and standard sensing applications. Available in three different body styles – 30mm metal, 22mm plastic and 15mm plastic – with a broad selection of operator types, circuit arrangements and connection options, the 440P is ideal for a wide variety of applications. These include material handling, packaging, elevators, escalators, scissor lifts, industrial trucks and tractors, cranes and hoists, overhead door as well as general safety guarding applications. The 22mm plastic body style is available in positive opening action two- and three-circuit models, with seven different operator types: adjustable roller lever adjustable rubber roller lever short lever hinge lever roller plunger dome plunger offset hinge lever The metal body, 30mm x 60mm style is available in positive opening action two- and four-circuit models and seven different operator types: metal roller plunger metal dome plunger metal short lever metal adjustable lever metal rod lever metal spring rod telescopic arm
