Protect machinery and ensure the safety of personnel—these switches have positive-force contacts that will open the circuit when actuated even if a spring fails or the contacts stick. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.

Shorter and thinner than other safety limit switches, these are sized to fit tight spaces. They protect machinery and ensure the safety of personnel. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. They send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects. All are NEMA and IP rated for protection from washdowns.

Rated NEMA 3S and IP69K, these switches can handle washdowns with high pressures and temperatures. They’re also protected from oil/coolant spraying, precipitation, and temporary submersion. When an object in motion contacts the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.

Install these limit switches where changing a battery or routing wires might be difficult—they power themselves when a moving object contacts the actuator. Place them up to 330 ft. away from the receiver (sold separately). These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator.

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. A simple automation solution that requires no programming, they activate when an object, such as a box rolling on a conveyor, pushes the actuator. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they go back to their original position as soon the actuator is released. Also known as 4-way and 5/2 valves.
