Description
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.).

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.

➃
Sequence 3, 7, and 8 devices are available but are not recommended where high speed cams or lever arm snap-back is present.
The application should be checked and No. 12 sequences substituted where possible.
Note: Type FT Foundry Switches are obtained by changing the “T” at the beginning of the equivalent type number above to “FT” (Example: FTUB1).
