Description
L100W Switches
Use the L100W Mill switches instead of other limit switches in the
following applications:
•
•
•
f L switches are not preceded by 9007. They are known as the
R.B. Denison
slack cable pull switches in the product offering.
L300W Switches
The L300W 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).

20 A continuous.
Where an operating sequence is required that is not possible
on other limit switches (35 choices with the L switches).
Where higher reset forces are required due to foreign material
interfering with lever arm operation, or where long heavy arms
must reset against gravity.

Conveyor belt limit switches are ideal for
policing the lateral movement of belt
conveyors. When the conveyor belt shifts, it
contacts the switch roller and a 12°
movement of the lever transfers the first set
of contacts. This set is usually wired to
initiate a warning alarm system to alert the
worker that the belt is moving off the rollers.
Further lateral movement of the belt, causing
the lever to move another 8°, trips the second
set of contacts. These contacts are normally
wired to the conveyor drive system and when
actuated stop the system, minimizing
damage to the conveyor or loss of material
on the belt.
