For technical details and part number configuration please see attached highlighted datasheet.

The 3300 XL Proximitor Sensor incorporates numerous improvements over previous designs. Its physical packaging allows you to use it in high-density DINrail installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting “footprint” with older Proximitor Sensor designs. The mounting base for either option provides
electrical isolation and eliminates the need for separate isolator plates. The 3300
XL Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby radio frequency signals. The 3300 XL Proximitor Sensor’s improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings, resulting in lower installation costs and complexity.
The 3300 XL’s SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen.

Bently Nevada 3300 XL Series of sensor systems are the best performing and longest lasting sensors available today. Featuring superior performance in a variety of harsh environments, our 3300XL series is the the result of over 50 years of transducer system engineering, which is why the Bently Nevada name is synonymous with best in class proximity sensor systems.
