Mixer Limit Switch With Arm

Mixer Limit Switch With Arm

This is a heavy-duty, fully assembled electrical limit switch with an attached roller arm, commonly used as a drum counter on rear discharge concrete mixers. The switch sends a signal to a cab-mounted counter each time the drum completes a revolution, allowing for accurate tracking of mix times. Its rugged, corrosion-resistant zinc die-cast body and sealed construction make it ideal for the harsh, wet environments of concrete production. This part is a critical replacement for worn or damaged switches to ensure accurate mix quality and operational data.

Key Features

• Heavy-duty die-cast zinc housing for durability in harsh environments.
• Sealed construction rated to NEMA 1, 3, 4, 4X, 6, 6P, 12, and 13 standards for protection against dust, water, and coolants.
• Side rotary head with an adjustable roller arm lever.
• Snap-action contacts for reliable electrical performance.
• Commonly used for drum rotation counting on McNeilus mixers.
