Pinpoint with safety More versions have been released by sensor market leader ifm electronic Ltd of their highly successful OJ miniature photocells, this time laser versions employing the safest of all emitters, the class 1 laser. The low energy class 1 (to IEC 60825-1) is considered the safest form of laser light, and as such doesn't even require special labelling. Low energy means safe; the performance is as great as ever with ranges up to 15m in the through-beam and 8m in the retroreflective versions. But it is pinpoint accuracy probably more than range that users turn to laser sensors for, and these are no exception. A target object need be no larger than 0.8mm to be detected over 1m by the through-beam version, and there a is a fully background-suppressed diffuse laser sensor in this family which will also detect an object smaller than a millimetre across from a distance of 150mm. Available also in two housing styles for ease of installation, the OJ Class 1 lasers can have lenses on the side, or at the front. Set-up couldn't be simpler with the pushbutton on the device, and the range of mounting accessories helps installation enormously. Electrical connnection of these PNP devices is via an industry-standard M8 connector. For more information on OJ miniature photocells click here
