The SM series from EATON electrical sector provides high performance and ease of use in an economical, compact package. A sensor can have the greatest performance in the world, but if it is slightly misaligned or the target is positioned at the wrong range, you will have reliability problems sooner or later. TargetLock™ not only simplifies sensor setup but visually confirms your sensor is positioned to operate with the highest possible reliability. In addition, TargetLock™ provides diagnostic information during use to inform you of impending problems before they result in equipment downtime. The SM series includes many other features that simplify use. Visible sensing beams on all models show you exactly where the sensors are pointing. The durable housing features multiple mounting options to easily fit on your equipment in the tightest of spaces. Full protection from overvoltage, reverse polarity and short-circuits reduces the chance of damage. Bright 360 deg LED indicators clearly show sensor status.
