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. These relays meet ISO and IEC standards for machine safety and can help achieve PL, SIL, or CAT system ratings.
