Right-angle bend fiber optic sensor

Right-angle bend fiber optic sensors are compact, durable, and designed for precise detection in tight or complex industrial environments.

Overview

Right-angle fiber optic sensors are specialized optical sensors where the fiber is bent at a 90-degree angle, allowing installation in space-constrained areas while maintaining accurate detection performance . These sensors are commonly used in industrial automation, including wafer mapping, IC pin detection, labeling machines, vibratory feeders, and other high-precision applications . The right-angle design enables easy mounting with minimal space requirements, often using a single nut for installation .

Key Features
  • Sensing Distance: Depending on the model, detection ranges can vary from 0–48 mm up to 90 mm, suitable for small targets as tiny as 0.1 mm .
  • Fiber Diameter and Core: Fiber cores typically range up to 1.0 mm, with outer diameters around 2.2 mm, providing stable signal transmission and low optical loss .
  • Bend Resistance: Designed to withstand bending, with a minimum bend radius of R25, ensuring consistent performance even in tight installations .
  • Materials and Durability: Probe heads are made from stainless steel or nickel-plated metal, offering pressure resistance, wear resistance, and rust prevention. Fibers may have fluorocarbon coatings for waterproof and oil-resistant performance .
  • Environmental Resistance: Many sensors are designed to resist temperature variations, vibration, oil, and chemical exposure, making them suitable for harsh industrial environments .
  • Fiber Options: Available in plastic or glass fibers, with cable lengths typically 1 m or 2 m, allowing flexibility in installation .
Applications

Right-angle bend fiber optic sensors are ideal for:

  • Tight-space detection in automated machinery and robotics
  • High-precision industrial tasks, such as IC pin detection, wafer mapping, and labeling
  • Harsh environments, including oil, water, and chemical exposure, due to protective coatings and durable probe materials
  • Flexible sensing setups, where adjustable sensing distances and fiber lengths are required
Advantages
  • Compact and space-saving design for installation in narrow areas
  • High sensitivity and low signal loss, ensuring reliable detection
  • Durable and long-lasting, resistant to bending fatigue, corrosion, and environmental stress
  • Customizable for specific industrial needs, including fiber type, length, and sensing distance

In summary, a right-angle bend fiber optic sensor platform provides a versatile, durable, and precise solution for industrial sensing applications where space is limited and environmental conditions are challenging. Proper selection of fiber type, sensing distance, and material ensures optimal performance for specific automation or detection tasks .
