Which sensor should I use to detect distance, number, and colour of wire inside the conector? When the dimension of terminal is so small, around 2 mm?
Detecting distance, number, and color of wires inside a connector, especially when the terminal is as small as 2 mm, requires a combination of precision and miniaturized sensors. Here’s what might work for each requirement:
- Distance Detection: A laser displacement sensor would be ideal for measuring the distance between objects with high accuracy in tight spaces. Compact models are available that can provide precise readings even in small areas like your 2 mm connector terminal.
- Counting the Wires: For counting the number of wires, you could use a vision sensor with image processing capabilities. A camera sensor with a high resolution and integrated image analysis software can be used to detect and count the wires by analyzing the captured images.
- Color Detection: A color sensor designed for industrial use would be your best bet here. Miniature color sensors are available that can differentiate wire colors in real time. You’ll need to make sure it’s sensitive enough for small targets like wires in your connector.
Combining these into a system, possibly with a vision sensor that handles both counting and color detection, would give you the functionality you need in such a small space.
