Optical window sensors are typically used for reliable detection and exact counting of fast-flying or falling parts in production or packaging processes. However, if the installation space is particularly small or if difficult working conditions arise, such as uncontrollable dust, solving this issue can become a challenge. The remedy is now here in the form of the BOH AI from the BAE MICROmote family with separate amplifier. They bring a high level of optical precision to the smallest of installation spaces together with functional diversity. The sensor head has been
