Background-suppressed photoelectric sensors use time-of-flight
Reliable background suppression and colour-independent detection with switch point setting to the nearest centimetre are features of the new OID and O5D photoelectric sensors from ifm electronic. The PMDLine sensors even detect shiny surfaces such as stainless steel without difficulty. Both the OID and O5D will sense an object at a distance of 2m, even against a background, and as such could be used to replace retro-reflective sensors.
These new developments employ time-of-flight measurement to combine the advantages of long ranges, reliable background suppression, visible red light and high excess gain in one unit. In the same price range as conventional sensors, the O5D and OID are clever alternatives to normal sensors at no extra cost.
Another advantage is its ease of use and switch point setting to the nearest centimetre. The O5D features "+/-" buttons and a display, while the OID can be set with a simple turn of the setting ring. A scale shows the distance set, in centrimetres or inches. The switch point can thus be set prior installation.
Shiny, matt, dark or light objects of any colour - the O5D/OID sensors always ensures optimum background suppression. The technology allows any angle of incidence, providing high flexibility of installation. The sensor is also IO-Link enabled, for example for reading the current value. These experts set the bar high for conventional sensors.
The O5D is supplied as a classic rectangular photocell, while the OID is in an M30 housing. Both are designed for DC PNP operation, with both open and closed outputs available via the industry-standard M12 connector.
