Bently Nevada 330780-50-CN 11mm Proximitor Sensor Overview

The Bently Nevada 330780-50-CN is a 3300 XL 11 mm Proximitor sensor made in the USA. It shares the same advanced features found in the 3300 XL 8 mm Proximitor Sensor. However, this 11 mm version offers larger measurement range capabilities. Specifically, the 330780-50-CN accepts one non-contacting 3300 XL 11 mm proximity probe. In addition, it works with extension cables for flexible system configuration. The thin design allows high-density DIN-rail installations. Alternatively, you can choose a traditional panel mount configuration. This particular model comes with the panel mount option pre-configured.

Technical Specifications

The Bently Nevada 330780-50-CN has a total system length of 5.0 meters (16.4 feet) . This length includes the probe, extension cable, and Proximitor sensor combined. The mounting option is panel mount with no additional hardware. Agency approval option CN indicates country specific approvals. Therefore, verify local acceptance before installation. Approximate dimensions are 6.35 cm x 6.12 cm x 8.13 cm for panel planning purposes.

Now consider the power requirements for this sensor. Specifically, the 330780-50-CN requires -17.5 Vdc to -26 Vdc without barriers. Maximum current consumption is 12 mA. When using barriers, the range becomes -23 Vdc to -26 Vdc. However, operation above -23.5 Vdc can reduce the linear range significantly. Supply sensitivity shows less than 2 mV change in output voltage per volt change. Finally, output resistance is 50 Ω for standard signal transmission.

Environmental & Temperature Range

The Bently Nevada 330780-50-CN operates across extreme temperature conditions. Specifically, operating temperature spans -52°C to +100°C (-62°F to +212°F) . Storage temperature ranges from -52°C to +105°C (-62°F to +221°F) . Relative humidity tolerance reaches 100% condensing conditions. However, the sensor is non-submersible when connectors are protected. It has been tested to IEC 68-2-3 damp heat standards. The Proximitor sensor material is A380 aluminum for lightweight durability.

RFI/EMI Immunity & CE Mark Approval

The Bently Nevada 330780-50-CN demonstrates excellent RFI and EMI immunity. Improved immunity allows European CE mark approvals without special mounting considerations. Therefore, nearby high frequency radio signals cannot adversely affect this transducer system. As a result, you can install the 330780-50-CN in various enclosures without worry. Moreover, no special shielded conduit or metallic housings are required. Consequently, this reduces both installation costs and complexity for your projects.

The 330780-50-CN includes SpringLoc terminal strips for easy wiring. These terminals require no special installation tools. Specifically, the SpringLoc design eliminates screw-type clamping mechanisms completely. Traditional screw clamps can loosen under vibration over time. Therefore, SpringLoc provides faster and more reliable field wiring connections.

Calibration & Target Compatibility

Proximitor sensors are supplied from the factory calibrated to AISI 4140 steel by default. This standard calibration suits most industrial applications. However, calibration to other target materials is available upon request. Therefore, contact us before ordering if your target material differs from AISI 4140 steel. The 330780-50-CN works with 3300 XL 11 mm proximity probes only. System lengths of 5 or 9 meters are available including the extension cable.

Key Features & Benefits

• 11 mm probe compatibility – The 330780-50-CN works exclusively with 3300 XL 11 mm probes.

• Thin profile design – Fits high-density DIN-rail or panel mount installations easily.

• Wide temperature range – Operates reliably from -52°C to +100°C.

• High RFI immunity – CE mark approved without special mounting considerations.

• SpringLoc terminals – No special tools needed for fast, secure wiring.

• A380 aluminum housing – Durable construction at only 0.35 kg weight.

Installation Guidelines

Follow these steps to install the Bently Nevada 330780-50-CN correctly. First, mount the Proximitor sensor on a panel using the 4-hole footprint. Second, connect the 3300 XL 11 mm probe to the sensor input. Next, attach the extension cable between the probe and the 330780-50-CN if needed. Then, wire the power supply using SpringLoc terminals with -17.5 Vdc to -26 Vdc. After that, connect the output signal wires to your monitoring system. Finally, verify the total system length does not exceed 5.0 meters.

However, do not operate the 330780-50-CN above -23.5 Vdc when using barriers. Otherwise, this reduces the linear measurement range. Also, keep the probe tip at the recommended gap for best accuracy. Above all, use only Bently Nevada approved 11 mm probes and cables with this sensor.
