The Model TA-TPS is a tripper position switch, which is a heavy duty limit switch commonly used to aid in positioning of the "tripper" on a conveyor with multiple discharge points or discharge chutes. The output contacts of the Model TA-TPS can control up to two separate circuits, one for machinery shutdown and one for an alarm.
Technical Specifications:
• The housing is cast aluminum, with optional epoxy or polyester powder coatings available. These coatings will provide protection against corrosion that is equal or greater than cast iron.
• The roller is a heavy duty white acetal material of 3" diameter.
• The unit is mounted on the conveyor by drilling (3) 13/32" diameter holes.
