Frequently Asked Questions

• What is the 40 mm unthreaded length used for?
  The -04 option provides 40 mm of smooth case before threads begin. This allows the probe to pass through a clearance hole before engaging the mounting thread.
• What is FluidLoc cable?
  FluidLoc is a specialized cable construction with enhanced fluid resistance. It provides superior protection in wet environments or applications with coolant exposure.
• What agency approvals come with the -05 suffix?
  The -05 option includes multiple agency approvals such as CSA, ATEX, and IECEx for hazardous area installations.
• Does this 1.0 meter 3300 NSv Proximity Probe require an extension cable?
  It depends on your Proximitor location. The 1.0 m length often connects directly, or you may add extension cable for longer distances.
• What torque value should I use for M10x1 installations?
  Use 11.3 N•m (100 in•lb) for standard installations. Do not exceed 33.9 N•m (300 in•lb) maximum rated torque.
• Is this probe suitable for submerged applications?
  The FluidLoc cable and Viton O-ring provide enhanced fluid resistance. Contact our custom design department for specific immersion requirements.
