Angled Fork Light Barriers
Angled and L-Shaped Fork Light Barriers for Tight-Space Detection and Offset Mounting
Angled fork light barriers operate on the through-beam principle, but use a bent or L-shaped housing to position the sensing gap where mounting space, part flow, or machine geometry makes a standard U-shaped fork less practical. They are well suited to compact installations for detecting labels, edges, small parts, and product presence in packaging, assembly, paper converting, and similar industrial automation applications.
IBIS supplies angled fork light barriers from di-soric and Dietz, with a stronger focus on di-soric models across this range. Many di-soric angled fork sensors are available with IO-Link, making them a stronger choice where parameter setting, diagnostics, status monitoring, and easier machine changeover are important. Dietz angled fork sensors remain useful conventional options in selected sizes and light-source types, but currently do not offer IO-Link models in this family.
Available light sources include infrared, visible red, laser visible red, and high-power versions for more demanding sensing conditions. Common fork openings range from 50 mm to 120 mm, with selected larger and special-format models also available, giving users options for different part sizes, sensing precision requirements, and installation constraints.

How to Choose the Right Angled Fork Light Barrier
Choose the correct angled fork light barrier by matching the sensor to the part geometry, available mounting space, light source, and required output/interface.
- Fork opening: Match the opening to the target size, label width, gap, or product path.
- Housing shape: Angled and L-shaped designs help when the sensing gap must be offset from the mounting point or where space is restricted.
- Light source: Infrared is useful for general detection, visible red helps with setup and alignment, laser visible red supports finer detection tasks, and high-power versions help in more demanding sensing environments.
- Resolution: Use finer-resolution models for labels, edges, thin materials, and small-part detection.
- Interface and output: Many di-soric models include IO-Link for diagnostics and parameter setting, while other models use conventional switching outputs for simpler integration.
- Application environment: Consider dust, oil, ambient light, stability requirements, and available installation space.
Applications for Angled Fork Light Barriers
Angled fork light barriers are used where a fixed sensing gap is needed, but a standard straight U-shaped housing is less practical because of machine layout or installation space.
- Label detection on packaging and converting equipment
- Edge detection and positioning tasks
- Part presence monitoring in assembly systems
- Product counting in conveyors and handling equipment
- Detection in compact stations where offset mounting is required
- Applications requiring stable fixed-gap sensing with limited installation space
