The Bently Nevada 330780-50-CN delivers the same proven performance as the 3300 XL 8 mm model but in a larger 11 mm package. Its compact, thin design supports both high-density DIN-rail installations and traditional panel mount setups. Enhanced RFI/EMI immunity enables European CE mark approval without extra mounting precautions. Furthermore, this immunity protects the transducer system from nearby high-frequency radio interference. SpringLoc terminal strips eliminate the need for special installation tools. As a result, they provide faster and more dependable field wiring connections.
Electrical Parameters
Input: Accepts one non-contacting 3300 XL 11 mm Proximity Probe and Extension Cable.
Power Requirement: -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption; -23 Vdc to -26 Vdc with barriers. Operation above -23.5 Vdc may cause reduced linear range.
Sensitivity: Less than 2 mV change in output voltage per volt change in input voltage.
Output Resistance: 50 Ω.
System Length
The Bently Nevada 330780-50-CN provides a 5.0 meter (16.4 feet) system length including the extension cable. This matches the “50” option in the product number.
Calibration Details
This Proximitor Sensor leaves the factory calibrated to AISI 4140 steel as standard. Calibration to other target materials remains available upon request.
Country-Specific Approval (CN)
The “CN” suffix in 330780-50-CN indicates this version carries country-specific agency approvals. This makes it suitable for installations requiring local regulatory compliance in certain regions.
RFI/EMI Immunity
Improved immunity allows this sensor to achieve CE mark approval without special mounting considerations. Consequently, you can install it in electrically noisy environments with confidence.
Proximitor Sensor Material
A380 aluminum construction provides excellent durability for industrial applications.
Temperature Range
Operating: -52°C to +100°C (-62°F to +212°F)
Storage: -52°C to +105°C (-62°F to +221°F)
Relative Humidity
The sensor withstands 100% condensing humidity. However, it remains non-submersible when connectors are properly protected. It has passed IEC 68-2-3 damp heat testing.
Dimensions (HxWxD)
Approximately 6.35 cm x 6.12 cm x 8.13 cm.
Mounting Options
The 3300 XL 11 mm Proximitor Sensor supports panel mount configuration as shown by the “50” option code. You can also install it on high-density DIN rails for space-saving layouts.
Wiring with SpringLoc Terminals
SpringLoc terminal strips make field wiring simple and reliable. First, strip the wire end to the correct length. Next, insert the stripped wire into the terminal opening. Finally, press down firmly to lock the connection in place. No specialized tools are needed for this process.
Placement Considerations
Although this model offers excellent RFI immunity, avoid mounting it directly next to high-power radio transmitters. This simple step ensures optimal measurement accuracy in all conditions.
Target Material Planning
For measurement targets made from materials other than AISI 4140 steel, request factory recalibration before placing your order. This proactive step guarantees accurate and reliable readings.

1. What does the “CN” approval option mean for the Bently Nevada 330780-50-CN?
The “CN” suffix indicates country-specific agency approvals. This version meets local regulatory requirements for certain regions, making it suitable for projects with specific compliance needs.
2. Can I use this sensor with a 9 meter system length instead of 5 meters?
No, the 330780-50-CN is fixed at 5.0 meters total system length. For 9 meter requirements, please order model 330780-90-00 instead.
3. Does operating above -23.5 Vdc damage the sensor?
It does not cause permanent damage. However, operation at a more positive voltage than -23.5 Vdc may reduce the linear measurement range. Always stay within -23 Vdc to -26 Vdc when using barriers.
4. Is this Proximitor Sensor compatible with non-AISI 4140 steel targets?
Yes, but factory recalibration is required. Please request this option when ordering to ensure accurate measurements for your specific target material.
5. How do I mount the 3300 XL 11 mm Proximitor Sensor on a DIN rail?
Its thin design fits standard high-density DIN rails. Simply snap the sensor onto the rail until you hear a click. No additional mounting hardware or tools are necessary.
