Fiber-Optic Photoelectric Switches

The highly flexible fiber-optic cable and small sensing end make it easy to position these switches in hard to reach areas. They detect the presence or absence of an object moving at high speeds with a light beam. Adjust the intensity of the light beam to better detect shiny or translucent objects. The fiber-optic cable can be cut to length. All are rated NEMA 6P and IP67 for protection from corrosion, washdowns and temporary submersion.

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 switches.

Time-Delay Fiber-Optic Photoelectric Switches

Set these switches to delay activation by up to fifteen seconds after detecting an object. They have a highly flexible fiber-optic cable and small sensing end, making it easy to position these switches in hard to reach areas. They detect the presence or absence of an object moving at high speeds with a light beam. Adjust the intensity of the light beam to better detect shiny or translucent objects. The fiber-optic cable can be cut to length. All are rated NEMA 6P and IP67 for protection from corrosion, washdowns and temporary submersion.
