Opto sensing made easy

Sensors & Transducers
The OG-series laser-based retro-reflective opto sensors from IFM Electronic provide reliable, precise sensing at long ranges, even in difficult environments. The OG retro-reflective sensors, which have standard M18 bodies, are currently available in two versions, with ranges of 4 m and 13 m, and can be used to detect targets as small as 1,5 mm and 3 mm respectively.
The sensors also feature exceptionally high excess gain, allowing them to continue to operate reliably even if the sensing beam is severely attenuated, either by atmospheric conditions or because of lens soiling. This feature, together with the patented fully sealed one-piece housings, which substantially exceed IP67 requirements, make OG laser sensors a good choice for use under difficult conditions, such as those frequently encountered in food manufacturing and the process industries. To ensure simple and accurate adjustment, OG laser sensors incorporate IFM's touch-to-teach setting technology.
Users simply press a button once with the target in place, then again with no target, and the sensor automatically adjusts itself for optimum performance. Beam modulation is turned off during the setting operation, increasing beam brightness, and making it easily visible for use as an aid to sensor and target alignment.
OG retro-reflective laser sensors are suitable for operation from DC supplies in the range 10 to 30 V, making them equally suitable for use on nominal 12 V and 24 V systems. The units each have a single short-circuit, overload and reverse-polarity protected output rated at 200 mA, which is user-selectable as light-on or dark-on. Connections to the units use a standard M12 connector.
Shorrock Automation believes that IFM laser opto sensors are competitively priced, and frequently offer the most cost-effective solution to demanding sensing applications.
