Background-suppressed photoelectric sensors use time-of-flight
Reliable long-range background suppression and colour-independent detection with easy switch point setting are the outstanding 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 can be used to replace retro-reflective sensors.
These new sensors employ time-of-flight technology to combine the advantages of long ranges, reliable background suppression, visible red light and high excess gain, all 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 the ease of use and switch point setting to the nearest centimetre. The O5D features '+/-' buttons and a display, while the OID can be set by simply turning the setting ring. A scale shows the distance set, in centimetres or inches, enabling the switch point to be set prior installation.
Whether they are being used with shiny, matt, dark or light objects of any colour, the O5D/OID sensors always ensures optimum background suppression. The technology enables any angle of incidence to be used, providing high flexibility of installation. The sensor is also IO-Link enabled for tasks such as remotely reading the current value, or setting and activating time delays.
The O5D is supplied as a classic rectangular photocell, while the OID is in an M30 cylindrical housing. Both are designed for DC PNP operation, with both open and closed outputs available via an industry-standard M12 connector. In addition, the M30 OID is available in an IP69K version for use in wet areas. Laser safety is not an issue, as both the OID and O5D are available as laser class 1 or class 2 devices.
