The PresencePLUS® low-angle ring lights from Banner Engineering Corp., Minneapolis, MN, connect to vision sensors or an external power supply to provide optimal illumination of an inspected part by enhancing the contrast of surface features. The low-angle ring lights can be used in applications such as illuminating stamped or dot-peen bar codes; detecting etchings in glass, metal, or plastic; and counting solder balls.

The 150-mm low-angle ring light uses three tiers of bright LEDs for high-intensity, low-angle illumination. Models are available with infrared or visible red LEDs and offer a choice of continuous or strobed operation through a dedicated strobe input line. PresencePLUS low-angle ring lights include a 2-m attached cable with threaded 3-pin Pico-style pigtail quick disconnect for direct connection to a P4 sensor, or flying leads to connect to a 24V DC power source.
