- **Caution**: 

### Q: What materials are sensing heads typically made from for industrial machinery?
**A**: Sensing heads are commonly manufactured from stainless steel for corrosion resistance, aluminum alloy for lightweight durability, engineering plastics for cost-effectiveness, and ceramic for high-temperature applications in machinery and equipment manufacturing.

### Q: What are the main components in a sensing head BOM?
**A**: The bill of materials for a sensing head typically includes the sensing element (active detection component), housing (protective casing), connector (electrical interface), and lens/window (for optical or protective purposes).

### Q: How does a sensing head function in positioning sensors?
**A**: The sensing head serves as the active detection element that directly interacts with targets to measure position, distance, or presence. It converts physical parameters into electrical signals for processing by the sensor system in industrial machinery applications.
