Conveyor Safety and Control Applications


Industries such as Power Generation, Manufacturing, and Mining use conveyor belts to transport bulk material. These industrial facilities present unique challenges to conveyor applications due to the abrasive materials they carry and their harsh environments.


How Limit Switches Are Used In Conveyor Applications

Heavy-duty limit switches are used on industrial conveyors to provide system monitoring and control, and safety measures. A limit switch is a precision snap-action switch that is encased to protect it from external forces, such as hazardous chemicals, water, oil, and dirt and is used to detect presence or absence in areas where physical contact is allowed.

Proper limit switch operation can be affected by environmental factors in bulk material handling conveyor applications. Sometimes, it is challenging to get electrical standards and motor applications to match the intended task. In dirty environments, like a mine, particles can get inside of the switch and eventually cause failure. In applications where product alignment along the conveyor is critical, belt issues can dramatically affect efficiency.

Conveyor Applications Limit Switches

Namco’s heavy-duty limit switches are designed with our unique SNAP-LOCK Technology to ensure accurate position indication, user safety, and reliable start and stop. SNAP-LOCK solutions have a “snap” action, which enables a quick action from one position to another, effectively eliminating dead band. The contacts are forced to be in one position or the other and cannot dwell in between open or closed. Instead of relying on spring or magnetic force, each switch has a locking mechanism that mechanically forces the contacts to stay closed until released by the trip lever. This technology eliminates any possible contact chatter due to vibration or seismic events. NAMCO heavy-duty limit switches require less downtime and more production time than low-quality, standard switches.

Namco Heavy Duty Limit Switches

Namco heavy duty limit switches excel in critical industrial, hazardous locations, navy and marine applications where typical limit switches would fail. Every Namco limit switch includes Snap-Lock technology for unparalleled reliability and has the ruggedness to operate under the most severe conditions.
