ifm’s newest O6 photocells will not only survive harsh environments, but also feature extra functionality via IO-Link.
IO-Link, supported by a consortium of the major automation companies, allows communication down to sensor level without any extra wiring.
In the O6 sensors many functions are accessible via IO-Link, such as range and sensitivity, light/dark switching and a test function, but ifm says of greater significance is the ability to add time delays to the signal.
The wet area versions of the O6 with IO-Link are constructed with a stainless steel housing, protection rating IP68 / IP69K, with optical performance optimised for the environment found in food production.
The reliable background suppression of the diffuse reflection version has proved a hit with users since it was first launched, as the light spot is well defined, background suppression unsurpassed, and immunity to steam or reflective backgrounds second to none.
The O6 housing is industry standard, with 1in hole centres, so retrofitting is simple.
The stainless steel O6 is also available as through-beam or retro-reflective system, with equally outstanding performance.
