Fork light barriers, also known as fork sensors or U-shaped photoelectric sensors, are precision optoelectronic devices designed for non-contact detection of objects passing through their fork-shaped sensing gap. These sensors integrate an emitter and receiver in a single housing, operating typically with infrared or visible red light. Key technical parameters include fork widths ranging from 5 mm to 220 mm, response times as low as 0.05 ms, and output configurations such as PNP, NPN, or push-pull. They offer high repeat accuracy and are immune to ambient light interference, making them ideal for high-speed counting and positioning tasks. In industrial automation, they are often referred to as light grids or fork photocells, depending on regional terminology.
These sensors are predominantly used in packaging machinery, bottling lines, printing presses, and material handling systems. They excel in detecting small parts, labels, caps, or transparent objects in conveyor belts and assembly lines. Their robust IP67-rated housings allow installation in harsh environments with dust, moisture, or vibration. Common applications include edge detection, hole detection, and object presence verification in automated production cells.
Subcategories within this category include standard fork light barriers, miniature fork sensors, and high-speed fork sensors. Key article codes often follow a pattern like FLB-XX-YY, where XX denotes the fork width in millimeters and YY indicates the output type (e.g., PNP or NPN). For example, FLB-50-PNP represents a 50 mm fork width with PNP output. Other common codes include FLS-10-NPN and FLS-30-PP for miniature and push-pull variants, respectively.
