Performance highlights

The ThreadChecker from Kaman is a high-performance, non-contact eddy current sensor system specifically engineered for thread presence verification. Utilizing Kaman’s proven eddy current technology, it accurately detects thread presence in conductive materials regardless of cleanliness, making it ideal for harsh or variable environments.

Usage conditions

This sensor operates reliably between 0°C to 70°C and is suitable for integration into automated systems with a switching speed up to 3 kHz. It is designed for in-die applications, enabling real-time thread detection during manufacturing processes. The electronics module supports both analog and switched outputs and includes protection features like reverse polarity and short-circuit protection.

Possible applications:

• Automotive part inspection lines
• In-die manufacturing and stamping operations
• Automated quality control stations
• Thread presence detection in metal components
• CNC machine validation

Advantages of choosing this product

The ThreadChecker simplifies integration with programmable logic controllers (PLC) and offers flexible signal options. Its universal electronics module is compatible with a range of probes, reducing the need for multiple SKUs. The built-in “Teach” function ensures accurate setup even in variable production environments.

Other important features:

• Five internal probe sizes: 2 mm to 10 mm
• Two external probes: 6 mm and 8 mm
• Solid-state NPN output with configurable polarity
• Analog output shows consistent 5VDC difference between threaded and unthreaded holes
• Thread indicator LED and health diagnostics
