Installation Guide for the 330980-71-05

Follow these steps for a proper installation of the 330980-71-05.

Step 1: Mounting the Proximitor Sensor

Firstly, choose either DIN rail or panel mount locations. Then, secure the 330980-71-05 Proximitor Sensor using the appropriate method. For DIN rail mounting, clip the unit onto a standard rail. For panel mounting, use screws through the mounting holes.

Step 2: Probe and Extension Cable Connection

After that, connect your 3300 RAM or 3300 NSv Proximity Probe. Then, attach the matching extension cable to reach the 330980-71-05. Ensure all connectors are fully tightened and protected from moisture.

Step 3: Power Supply Wiring

Then, connect a DC power supply to the SpringLoc terminals. Specifically, provide between -17.5 Vdc and -26 Vdc without barriers. If barriers are present, provide -23 Vdc to -26 Vdc instead. Therefore, avoid operating above -23.5 Vdc to maintain full linear range.

Step 4: Output Signal Wiring

Furthermore, connect the output signal wires to your monitoring system. The 330980-71-05 has a 50 Ω output resistance. Therefore, use a 10 kΩ load for optimal performance.

Frequently Asked Questions (FAQs) About the 330980-71-05

Q1: What is the difference between standard 3300 XL and NSv versions?

The 330980-71-05 NSv version has a thinner design than the standard 8 mm Proximitor Sensor. Consequently, it fits into high-density DIN rail installations. In addition, it offers improved RFI/EMI immunity for CE compliance. Therefore, the NSv version is ideal for space-constrained panels.

Q2: What power supply should I use with the 330980-71-05?

The 330980-71-05 requires a negative DC voltage supply. Firstly, use -17.5 Vdc to -26 Vdc at 12 mA maximum without barriers. However, with barriers installed, use -23 Vdc to -26 Vdc instead. As a result, operation above -23.5 Vdc may reduce the linear range.

Q3: What target material is required for accurate measurement?

The 330980-71-05 is calibrated specifically for AISI 4140 steel targets. Specifically, the target must be 31 mm (1.2 in) diameter or larger. Consequently, accuracy and interchangeability specifications do not apply with other materials.

Q4: What is the operating temperature range of this sensor?

The 330980-71-05 operates between -52°C and +100°C (-62°F to +212°F). In addition, it can be stored between -52°C and +105°C (-62°F to +221°F). Therefore, this sensor works in extreme environmental conditions.

Q5: Does the 330980-71-05 work in humid environments?

Yes, it does. The 330980-71-05 withstands 100% condensing humidity. However, it is not submersible unless connectors are properly protected. The sensor has been tested to IEC 68-2-3 damp heat standards. Therefore, it is suitable for most humid industrial environments.
