Immediately cut power to machinery by breaking the light beam between two barriers. Light beams can travel up to 32 or 65 feet between the transmitter and receiver. They’re rated IP67, so they can be used in wet areas. For a complete switching system, combine a transmitter and receiver, safety relay, and connectors (all sold separately).
These switches can be configured for complex setups. To selectively allow material to pass through the sensing field, you can program the system to allow one or more beams to be broken without shutting off your machine. To create a perimeter guard that bends around corners, add mirrors to reflect light beams at an angle.
Note: These switches cannot be used with a full-revolution clutch press or machine. Use only with machinery that can consistently and immediately stop anywhere in its cycle.

Finger-safe switches trigger from objects the size of a finger passing through. Those with Bluetooth let you monitor switching status, beam alignment, and other data on your phone.

Hand-safe switches trigger from objects the size of a hand passing through—but not slimmer objects such as a finger. For switches with a light beam height up to 9.4", you’ll need four fixed or two swivel brackets. For switches with a light beam height of 12.6" and greater, you’ll need four fixed or four swivel brackets.
Swivel brackets can be adjusted during and after installation for easy alignment.

Safety relays send a signal to shut off your machinery when the light beams are breached and restart when the issue is resolved. IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits. Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation. These relays meet ISO and IEC standards for machine safety and can help achieve PL, SIL, or CAT system ratings.

Light Beam Safety Barrier Switches for Long Distances

Spanning up to 230 ft.—roughly the length of a commercial airplane—these safety barrier switches cut power to large machinery to prevent damage or injury. They trigger the instant a person or object crosses the light beams between the transmitter and receiver. To selectively allow material to pass through the sensing field, you can program the system to allow one or more beams to be broken without shutting off your machine. To create a perimeter guard that bends around corners, add mirrors to reflect light beams at an angle. Rated IP67, these switches withstand wet conditions.
For a complete switching system, combine a transmitter and receiver, safety relay, and connectors (all sold separately).
Note: These switches cannot be used with a full-revolution clutch press or machine. Use only with machinery that can consistently and immediately stop anywhere in its cycle.

Harsh Environment Light Beam Safety Barrier Switches
Shut off machinery on your roughest, dirtiest job sites the second someone or something gets too close. Shielded by a polycarbonate housing, these safety barrier switches withstand impact better than standard models. Rated IP69, they’re sealed to keep out dust and high-pressure, high-temperature washdowns, so they'll stand up to mud, water, and heat on site. They're often used in construction zones and mining operations. When conditions are too harsh for inspections, use Bluetooth to send diagnostics to your phone. Simply connect to the app to monitor switching status, beam alignment, and other data from afar.
These switches trigger when the light beams between the transmitter and receiver are interrupted. To selectively allow material to pass through the sensing field, you can program the system to allow one or more beams to be broken without shutting off your machine. To create a perimeter guard that bends around corners, add mirrors to reflect light beams at an angle.
For a complete switching system, combine a transmitter and receiver, which are sold together, with a safety relay (sold separately).
Note: These switches cannot be used with a full-revolution clutch press or machine. Use only with machinery that can consistently and immediately stop anywhere in its cycle.
Finger-safe switches trigger from objects the size of a finger passing through. Hand-safe switches trigger from objects the size of a hand passing through.
Safety relays send a signal to shut off your machinery when the light beams are breached and restart when the issue is resolved. IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits. Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation.

Harsh Environment DC Universal-Object Proximity Switches

Micro
M12 Plug
Rated NEMA 6P, 12, IP68 and IP69K, these switches protect against corrosion and high-pressure, high-temperature washdowns. Also known as capacitive proximity switches, they remotely sense both metallic and nonmetallic objects but their strength is in sensing materials such as plastic, ceramic, and clear targets. 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). They mount flush with the surface of any material, including metal, and are also known as embeddable or shielded switches. The 4-pole Micro M12 plug connects to cables with sockets (sold separately), allowing you to quickly connect and disconnect the switch.
Also available: If you don’t see the switch you need, please select 6693T999 and specify manufacturer and manufacturer part number.
