9007B1

The ambient temperature range for the limit switches described in the document is -10°F (-23°C) to +185°F (85°C) at full rated load, and up to 220°F (104°C) ambient with a single coil load.

The 9007T Mill switches should be used instead of other limit switches in 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. Additionally, they should be used where an operating sequence is required that is not possible on other limit switches, as the 9007T Mill switches offer fifteen sequences with different operating options. These switches are suitable for various applications due to their versatility and higher current load capacity.

The type of limit switch designed specifically for rough foundry applications to prevent jamming of the lever arm due to build up of sand is the Type FT. This switch has a shaft that extends entirely beyond the switch case to prevent jamming of the lever arm, and it comes with a dust boot to further prevent sand packing and allow free movement of the lever arm. The Type FT switch is extremely rugged and able to handle the rough applications encountered in foundries, mills, machine tool, and similar industries. It can withstand hot falling sand up to 300°F (149°C) .
