All models feature remote-start operation, ESD-safe construction, and a front mounting flange for robotic integration. ##### NFA-Series Model Chart | Model | Item Number | Driver Type | Torque Range | Adjustable RPM | Drive Size | Weight | | --- | --- | --- | --- | --- | --- | --- | | NFA150-A ESD | 145861 | Remote Start | 2.6–13 lbf.in (29.4–147 cN·m) | 800–1700 | 1/4" Female Hex | 18.4 oz | | NFA220-A ESD | 145862 | Remote Start | 5.2–19 lbf.in (58.9–215.8 cN·m) | 600–1200 | 1/4" Female Hex | 18.4 oz | | NFA450-A ESD | 145863 | Remote Start | 6.1–39 lbf.in (68.7–441 cN·m) | 300–600 | 1/4" Female Hex | 18.4 oz | *Specifications are based on the BFA & NFA-Series Product Brochure.* --- ### Model Selection Guide | If you need: | Recommended Model | | --- | --- | | Medium-torque robotic fastening | NFA150-A | | Higher torque automated assembly | NFA220-A | | Maximum torque robotic fastening | NFA450-A | | Faster cycle times | NFA150-A | | Highest torque capacity | NFA450-A | --- ### Compatible Accessories | Accessory | Purpose | | --- | --- | | STC40-FA Transformer | Required power supply | | Mountz Scout Screw Counter | Screw counting and error-proofing | | 1/4" Hex Power Bits | Fastening applications | | Robotic Mounting Hardware | Automated integration | --- ### Transformer The NFA-Series requires the **STC40-FA transformer** for operation. **The STC40-FA provides:** - 30/40 VDC output - Over Heat Protection (OHP) - Over Current Protection (OCP) - LED tool status display - Compatibility with the Mountz Scout Screw Counter The transformer supports all NFA-Series models and is designed for continuous production environments. --- ### Setup & Adjustment 1. Mount the NFA-Series screwdriver using the integrated front mounting flange. 2. Connect the screwdriver to the STC40-FA transformer. 3. Connect the transformer to the automation controller or PLC. 4. Install the appropriate 1/4" hex driver bit. 5. Adjust the torque setting using the external torque adjustment scale. 6. Verify torque output with a calibrated torque analyzer before production. 7. Connect the Mountz Scout Screw Counter if screw counting or error-proofing is required. 8. Run sample fastening cycles and verify communication with the robotic system before beginning production. ### Common Applications **The NFA-Series is commonly used in:** - Robotic assembly systems - Automated production lines - Automotive manufacturing - Aerospace assembly - Industrial equipment manufacturing - Electronics production - Medical device manufacturing - High-volume fastening applications requiring remote-start operation --- #### Use Cases (Real-World Examples) Robotic Assembly **Problem:** Automated assembly systems require a screwdriver that can deliver repeatable torque and integrate with robotic equipment. **Solution:** The NFA-Series combines remote-start operation, a front mounting flange, and a precision automatic shut-off clutch for robotic and fixtured fastening applications. --- #### Higher-Torque Automated Fastening **Problem:** Automated assembly applications require more torque than low-torque robotic screwdrivers can provide. **Solution:** NFA-Series models cover torque ranges up to 39 lbf.in, supporting medium- and higher-torque robotic fastening applications. --- #### ESD-Sensitive Manufacturing **Problem:** Electrostatic discharge can damage sensitive components during automated assembly. **Solution:** All NFA-Series models are ESD designed for use in static-sensitive production environments. --- #### High-Volume Automated Production **Problem:** Continuous production lines require fastening tools that operate reliably with minimal heat buildup and maintenance. **Solution:** The brushless motor design supports continuous operation while reducing maintenance requirements associated with conventional brushed motors. --- #### Error-Proofing Applications **Problem:** Manufacturers need to verify that all required fasteners have been installed before completing an assembly. **Solution:** The NFA-Series can be connected to the Mountz Scout Screw Counter to support screw counting and improve assembly quality. --- ### Maintenance -
