• Max cable length to monitor: 305 meters (1000 feet).
• Frequency response: See manufacturer graphs for roll-off at extended distances.
• Connector type: Miniature coaxial ClickLoc with standard cable.
• Short cable advantage: 0.5 m length minimizes signal loss in confined spaces.

Frequently Asked Questions (FAQ)

• When should I choose the 170 mm unthreaded length?
  Use the 330103-17-23-05-02-05 when you need to pass through thick insulation, bearing housings, or safety barriers before threading.
• Does the 0.5 m cable require a special Proximitor?
  Yes, always pair this probe with a Proximitor calibrated for 0.5 meter cable length.
• What approvals does the -05 suffix provide?
  It includes CSA, ATEX, and IECEx certifications for international hazardous locations.
• Can I extend the cable further?
  Field wiring between Proximitor and monitor can reach 305 m, but never extend the probe cable itself.
