A belt conveyor usually consists of two or more pulleys, with a continuous loop of material (belt) that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. There are two main industrial classes of belt conveyors: general material handling (moving boxes along inside a factory) and bulk material handling (transporting industrial/agricultural materials).

Honeywell manufactures many MICRO SWITCH switches that may be used in conveyor applications. They are designed to help control position, flow, and machine safety.

• MICRO SWITCH LSA Series (HDLS) heavy-duty limit switches are often used on conveyors to reliably indicate position to system controls, often found in many harsh indoor and outdoor environments.
• MICRO SWITCH 2CPS Series cable-pull emergency stop switches often control access around the conveyor perimeter or provide emergency-stop cable-pulls along the conveyor.
• MICRO SWITCH GSX Series safety switches in an explosion-proof housing are used in outdoor, above-ground, potentially explosive environments, such as grain handling conveyors, or oil and gas applications. Utilized to stop system operation when the switch is triggered.
• MICRO SWITCH LSX Series hazardous location switches stop system operation when the switch is triggered. Often applied for door or diverter position detection in outdoor, above-ground, potentially explosive environments, such as grain handling and oil/gas applications.
