1 Limit es 80T Introduction Plug-in Style 80T-AP with escription NonPlug-in Style 80T-Awith Bulletin 80T limit switches are ideal for applications in which heavy duty pilot ratings, small size, a high degree of versatilityandaruggednematype and oiltight construction are desirable. An important factor in the automation of industry, these limit switches are being applied extensively on conveyor systems, transfer machines, automatic turret lathes, milling and boring machines, radial drills, and many other types of modern, high speed production equipment. High egree of Versatility Bulletin 80T limit switches can be mounted in any position, with operating heads that can be rotated and fastened inanyoneoffourpositions90 apart. Most operating levers are interchangeable and can be rotated and clampedinanypositionthrough0. Accessories can be added to switches already in the field. NEMAType,andP Oiltight Construction 80T limit switches feature NEMA Type and construction with synthetic rubber seals to protect the operating parts against entry of oil, dust, abrasives, water and coolant, within the limits of NEMA-specified tests. Plug-inlevertypeexceptlow-torquemodels. Rugged, ependable Contact Block The contacts used in Bulletin 80T switches are snap-action type with high snap-through force resulting in minimum contact rebound. ouble break, fine silver contacts are electrically independent, but cannot be used on opposite polarities. Easy Mounting and Wiring Each switch base has four mounting holes: two through holes for front mountingandtwotappedholesinthe back for rear mounting. The pressure plate type terminals on the contact blockfacetothefrontoftheswitchand have ample wiring space around them.

This openingwilloccurevenintheeventof acontactweldcondition,upto0 Newtons. Type es These switches are operated by means ofaleverwhichisclampedtoaknurled shaft extending from the operating head. type switches can be equipped with a variety of operating levers: roller lever, adjustable roller lever, micrometer adjustment roller lever, rod lever, one-wayrodorrollerleverandfork lever.thesecanbeused interchangeably on all lever type switches except the low operating force switch. Push Type es These switches are actuated by means ofarodorplungerlocatedonthetopor side of the operating head. Pushing the plunger into the head causes the contacts to operate. Two types of plungers are available: rod type and steel roller. Side push rod switches can be supplied in spring return or maintained contact constructions. An adjustable length top push rod is also available. The contacts are snap-acting with high snap-through force resulting in minimum contact rebound. Wobble Stick and Cat Whisker Type es Bothswitchesareactuatedbyarodor wireextendingfromthetopofthe operating head. Moving the rod through a specified angle in any direction causes the contacts to operate. All wobble stick and cat whisker switches are supplied with spring return construction only. The contacts are snap-action type with high snap-through force resulting in minimum contact rebound. ual es The dual switch is actually two limit switches which function independently buthaveacommonenclosure.these switches are used for installations where two switches would be mounted sidebyside.thereisasavingon installation time and fittings(see page --7). Plug-in es Plug-in style limit switches can reduce costly downtime by eliminating the need for rewiring switches. The head and switch body can be replaced without disturbing the wiring chamber in the base. These units, featuring a castle lock head design, snap-action contacts and reliable plug-in connection are available in -circuit or -circuit construction. Plug-in style limit switches are listed on page --. Four-Circuit NonPlug-in es These switches contain two single pole single throw contact blocks(a total of two N.O. and two N.C. contacts) mountedinacommonenclosure.the blocks are mounted one above the other in the vertical limit switch construction,orsidebysideinthe horizontal construction. plungers are mechanically coupled in both constructions. When actuated, contacts in both blocks are operated. These switches in both types of construction are listed on page --.
