Sensor Switches

Sensor Switches

Detect moving objects from a distance, triggering a circuit to open or close

Linear Motion Position-Measuring Transmitters

Linear Motion Position-Measuring Transmitters

Measure the position of an object moving in a straight line; also known as string pots

Magnetic Switches

Magnetic Switches

Actuate when a magnet comes within sensing distance; often used to detect when doors or windows open

Snap-Acting Switches

Snap-Acting Switches

Open and close circuits quickly to minimize arcing and sticking; often used as door-open indicators

Potentiometers

Control speed, volume, and light intensity by varying electrical flow; also known as rheostats

Switch Mounts

Mount sensor switches to panel cutouts, tank walls, or conveyors

IO Link Programmers

IO Link Programmers

Configure your IO Link devices without a PC, outlet, or separate software

Light Curtains

Immediately cut power to machinery when anything blocks the light beam

Sensor Switch Transmitters

Sensor Switch Transmitters

Monitor objects, switch equipment on and off, and send data to control systems with a single device

Relays

Electrically open and close circuits to control power to lights, motors, and other equipment

Development Board Sensor Modules
