G Banner Engineering Corp. - Minneapolis, MN USA - www.bannerengineering.com Tel: 763.544.3164 9 119223 ## **Apertures** Opposed-mode Q12 sensors (standard models only) may be fitted with apertures to narrow or shape the sensor’s effective beam to more closely match the size or profile of the objects being sensed. A common example is the use of “line” (or “slot”) type apertures to sense thread. NOTE: The use of apertures will reduce the sensing range (see table below). |**Model**|**Description**|**Description**|**Reduced Sensor Range**
