Thread Detection (Thread Sensor) Probes

Automate manufacturing with thread detection sensors that identify threaded vs. unthreaded holes.

Thread Detection probes are specialized versions of our standard eddy-current displacement probes. They have extended sensing tips to allow easier penetration of tapped/untapped holes and to allow the sensing field to more easily engage the sides of the holes.

See our Thread Detection Application Note for details on using these probes with our standard sensor electronics.

Probe Selection

Selecting the right probe is dependent on the material type (ferrous vs. nonferrous) and the tapped hole size. The charts below identify the probe model required for your specific sensing needs.

Thread Detection Probe Mechanical Details

Probe Operating Environment

• -25°C to +125°C IP67

Probe Cables

Standard probes have PUR (polyurethane) jackets. High-Temperature probes have FEP jackets. FEP cables can be custom ordered for standard temperature range probes.

More details on probe cabling are available in our Eddy-Current Probe Cabling Considerations TechNote.

Mounting Accessories

To minimize the chance of probe damage due to broken taps or misalignment, use mounting cushions for mounting probes. Size is selected to match the probe.
