Photoelectric sensors for web and object-edge detection - Balluff Inc.

EdgeMaster photoelectric sensors detect and monitor web or object edges.

EdgeMaster photoelectric sensors detect and monitor web or object edges. The sensors help reduce or eliminate problems such as skew, material shifts, object alignment, and web material drag or stretch, thereby increasing output and lessening changeover times.

EdgeMaster sensors come in four types: The BAV MA Series, with fixed dual optical-axis edge detection, provides two independent discrete outputs to show edge-position change. The BGL C Series is a photoarray sensor for proportional analog or dual discrete outputs based on the amount of light blocked by the edge of the material inside the sensors’ viewing area, with a 0.08-mm resolution. The BOL 27 version projects a 150 mm line of light over an edge against a reflective tape to provide an analog and discrete output for accurate position feedback. The BGL 21 is suitable for contrast mark or label detection in high-speed web-based applications.
