6 presentation, application severe duty limit switches 0 9007 mill and foundry switches conforming to ne ma a600 and ul508 type t ? ideal for applications requiring extr a heavy duty contact ratings, or higher operating and reset forces. rugged mechanical construction with several different operating sequences in one basic switch. type ft ? designed specifically for rough foundr y application. the shaft is entirely beyond the switch case to prevent jamming of the lever arm due to build up of sand. a dust boot is furnished as standard to further prevent sand packing and allow free movement of the lever arm. an extra l ong shaft bearing makes the switch extremely rugged and able to handle the rough applicati ons encountered in foundries, mills, machine tool and similar industr ies. the switch will withstand hot falling sand up to 300 f (149 c). type t and ft enclosure ? oil-tight, dust-tight, water-tight, drip-tight meets nema 2, 4, and 13 requirements. die cast zinc construction. operating sequences ? fifteen sequences availabl e. universal type has 12 different operating sequences with cw only, ccw only, and neutral position operation. standard type has three ope rating sequences with cw and ccw operation. various sequences will give quick make and break, spring return with maintained contact, or slow make and br eak. most sequences ar e convertible by removing the base plate and adjusting the positioning plate and/or latches ambient temperature range ? 10 f (-12.2 c) to 185 f (85 c) ambient at full rated load, up to 220 f (104 c) ambient with single coil load. lever arm ? die cast zinc construction wi th hardened, oil-impregnated, sintered iron rollers. conduit ? 0.5" standard / 20 mm optional - form m11 mounting ? four baseplates provide end or side mounting holes and/or manifold mounting. all mounting holes are 0.25" (6.35 mm) diameter. two tapped holes on each side of switch allows side mounting. contacts ? spdt, double break and three point double throw single break. silver contact tips. phenolic contac t block. nylon liner. polarity must be same on double throw contacts. description 9007 (convertible sequence) 9007t mill switches use the 9007t mill switches instead of other limit switches in the following applications: 1 where the current load exceeds the typical heavy duty limit switch contact rating of 10 a and falls within the range of up to 20 a continuous. 2 where an operating sequence is required that is not possible on other limit switches. fifteen sequences are available. universal type has twelve different operating sequences with cw only, ccw only and neutral position. standard type has three operating sequences with cw and ccw operation. 3 where higher reset forces are required due to foreign material interfering with lever arm operation, or where long heavy arms must reset against gravity. 9007ft foundry switches the 9007ft foundry switches are for use in foundries or mills where the applications described above are required, and where falling foundry sand or similar material could build up and jam the operating mechanism. the shaft has a dust boot and extends from the switch case, preventing sand build up around the shaft. the devices can withstand hot falling sand up to 300 f (149 c.). 9007t mill switches 9007ft foundry switches pages 8 and 9 pages 10 and 11 application information interpretation of reference numbers: p a g es 31
