Key Features
System Interchangeability: Supports complete interchangeability of 3300 XL series probes, extension cables, and Proximitor sensors without the need for individual matching or bench calibration .
Backward Compatibility: Electrically and physically interchangeable with non-XL 3300 series 5mm and 8mm components .
Flexible Mounting: Can be mounted on a high-density DIN rail or in a traditional panel mount configuration using the same 4-hole footprint as older designs. The mounting base provides electrical isolation .
Secure Connections: Features gold-plated ClickLoc™ connectors that provide a tactile "click" when properly seated, preventing loosening from vibration .
API 670 Compliance: The 3300 XL 8mm system fully complies with the American Petroleum Institute's API 670 Standard (4th Edition) .
