Severe Duty Limit Switches

9007 Mill and Foundry Switches

Conforming to NEMA A600 and UL508

Description

9007T Mill Switches

Use the 9007T Mill switches instead of other limit switches in

the following applications:

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.

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.

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.).

Application Information

Type T

— Ideal for applications requiring extra 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 foundry 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 long shaft bearing makes the switch extremely

rugged and able to handle the rough applications encountered in foundries, mills,

machine tool and similar industries. 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 available. Universal type has 12

different operating sequences with CW only, CCW only, and neutral position

operation. Standard type has three operating sequences with CW and CCW

operation. Various sequences will give quick make and break, spring return with

maintained contact, or slow make and break. Most sequences are 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 with 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 contact block. Nylon liner. Polarity must be same on double

throw contacts.
