Industrial Applications

1. Conveyor Belt Speed Monitoring in Packaging Lines

Industrial packaging lines demand precise speed control for conveyor belts to synchronize stages like filling, sealing, and labeling. The TVI50T encoder can be mounted on the conveyor's drive shaft to provide real-time speed feedback to the control system.

Problem Solved

Ensures accurate and consistent product flow, preventing bottlenecks or misalignments due to speed variations. The high resolution (up to 1024 ppr) allows for fine speed adjustments, while the compact 50 mm diameter fits well into space-constrained machinery. The IP54 rating protects against dust and splashes common in packaging environments.

2. Machine Tool Position Feedback for CNC Routers

CNC routers require accurate position feedback for their X, Y, and Z axes to ensure precise cutting and shaping of materials. The TVI50T encoder can be integrated with lead screws or rack-and-pinion systems to monitor the exact linear position of the cutting head or workpiece.

Problem Solved

Provides reliable position data to the CNC controller, enabling high-precision machining operations. The robust design, including an aluminum housing and stainless steel shaft, ensures durability in a workshop environment, while the incremental push-pull/RS-422 output is compatible with standard industrial controllers for precise interpolation and motion control.

3. Robotic Arm Joint Angle Measurement

Industrial robotic arms utilize encoders to monitor the angular position of their joints, which is crucial for precise movement, trajectory planning, and repeatability. The TVI50T can be used in lighter-duty robotic applications where its compact size and high resolution are beneficial for joint angle sensing.

Problem Solved

Enables accurate joint angle feedback, allowing the robot to perform complex tasks with high precision and repeatability, such as assembly, pick-and-place, or welding. The short-circuit protected output enhances system reliability, and the wide operating temperature range (-10 to 70 °C) suits typical factory conditions.
