Safely detect the presence or absence of an object moving at high speeds with a light beam. These switches produce a low-current, low-voltage NAMUR signal, so they won’t create sparks or ignite in hazardous locations. ATEX and IECEx certified, they meet international standards to protect against explosion in environments containing flammable gases and combustible dust. Switches must be connected to the required barriers (sold separately), which reduce the current and voltage flowing from your power source. Unlike the switches, the barriers must be installed in a separate nonhazardous area.

These switches can send a signal to programmable logic controllers (PLCs) to support automated processes within your system. They are CE marked to meet European health, safety, and environmental protection requirements. Rated IP67, they’re protected against dust, washdowns, and temporary submersion.

Direct-sensing switches detect objects when light reflects back from the object. They have a shorter sensing distance than reflector sensors but don’t require a separate reflector.

Reflector switches detect an object when it passes between the switch and the reflector (not included), interrupting the beam. They have a longer sensing distance than direct-sensing switches.
