Choosing a Proximity Switch
More
Photoelectric Switches
Detect the presence or absence of an object moving at high speeds with a light beam. These switches have a longer sensing distance than proximity and ultrasonic switches.
Direct sensing switches detect objects when light reflects back from the object. The transmitter and receiver are in the same housing, so they fit in confined spaces.
Receiver switches detect objects when an object breaks the light beam between the transmitter and receiver (both included). They have a longer sensing distance than direct-sensing and reflector switches.
Reflector switches detect an object when it passes between the switch and the reflector, interrupting the beam. They have a shorter sensing distance than receiver switches but are quicker to wire. They have a longer sensing distance than direct-sensing switches.
Adjustable switches can increase the intensity of the light beam to better detect shiny or translucent objects. Switches with an ultraviolet light beam are good for detecting clear materials like plastic or glass, which absorb more UV light than infrared or visible light.
Switches with DC input voltage produce PNP or NPN signal output. To determine which signal output to choose, use Testers for Proximity and Photoelectric Switches (not included).
Switches with a plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
Switches with IO Link can be configured remotely when connected to a programmable logic controller (PLC), a human machine interface (HMI), or a computer. They let you remotely change settings, read measurements, and receive error messages.

M12 Plug
Also known as inductive proximity switches, these detect metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. Sensing distance is based on the target material. The distance listed is for mild steel. They’re often used with programmable logic controllers (PLCs) and produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).
Flush switches, also known as embeddable or shielded switches, can be mounted so that the sensor face is level with the surface of any material, including metal. They’re more accurate than projecting switches at close range and can be mounted close together without causing interference. Projecting switches, also known as non-embeddable or unshielded switches, must be mounted with the area around the sensor face free of metal. They have a longer sensing distance than flush switches with the same diameter.
Switches with a plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
Switches with IO link can be configured remotely when connected to a PLC, a human-machine interface (HMI), or a computer.
IP67 and IP68 rated switches are protected from temporary submersion. IP69K rated switches are protected from high-pressure, high-temperature washdowns. NEMA 6P rated switches are protected from corrosion and washdowns.

DC Metallic-Object Proximity Switches for Robotic Welding
Check the position of your torch or workpiece for accuracy during robotic welding. These switches are robust enough to handle changes in temperature and magnetic fields from welding to help reduce false triggers. A coating prevents weld spatter buildup to keep readings accurate and maximizes the sensing distance Also known as inductive proximity switches, they’ll detect metallic objects even if they’re obscured by water, oil, dirt, or a surface finish.
Flat-Body switches can be easily mounted to flat surfaces. They are prewired with a M12 cable. PTFE plastic insulation on the cable prevents weld spatter from building up along its length.
Flush switches, also known as embeddable or shielded switches, can be mounted so that the sensor face is level with the surface of any material, including metal. They’re more accurate than projecting switches at close range and can be mounted close together without causing interference.
To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).
