739-109 - Wago

739-109 Frequently Asked Questions (FAQs)

• What is the recommended torque for screwing the connector onto a PCB?
  The recommended torque is 0.5 Nm to 1.5 Nm, depending on the specific application and PCB material. It's essential to follow the manufacturer's guidelines to avoid damaging the connector or PCB.
• Can I use the 739-109 connector in high-vibration applications?
  Yes, the 739-109 connector is designed to withstand vibrations up to 10 g according to IEC 60068-2-6. However, it's crucial to ensure proper mounting and screwing to maintain the connector's integrity.
• Is the 739-109 connector suitable for use in harsh environments, such as high temperatures or humidities?
  The 739-109 connector is rated for operating temperatures between -40°C and 125°C and can withstand humidities up to 95% RH. However, it's essential to consider the specific environmental conditions of your application and consult with WAGO's technical support if necessary.
• Can I use the 739-109 connector with wire sizes other than the recommended AWG 20-24?
  While the 739-109 connector is optimized for AWG 20-24 wires, it can accommodate smaller wire sizes (AWG 26-30) with reduced current ratings. However, using larger wire sizes may compromise the connector's reliability and is not recommended.
• Are the 739-109 connectors compatible with automated assembly and reflow soldering processes?
  Yes, the 739-109 connectors are designed for automated assembly and reflow soldering processes. They meet the requirements of IEC 61760-1 and can withstand the temperatures and stresses associated with these processes.
