79109-1021 Frequently Asked Questions (FAQs)

  • The recommended torque for the screw terminals is 0.5-0.7 Nm (4.4-6.3 in-lbs). It's essential to follow this torque specification to ensure reliable connections and prevent damage to the connector.
  • Yes, the 79109-1021 connector is designed to withstand vibrations and can be used in high-vibration applications. However, it's crucial to ensure proper mounting and secure the connector to prevent damage or disconnection.
  • The 79109-1021 connector has a IP67 rating, which means it's protected against dust and water ingress. However, it's essential to follow proper sealing and installation procedures to maintain the IP67 rating. Additionally, consider using additional protection measures, such as conformal coating or potting, for extreme environmental conditions.
  • While the datasheet recommends AWG 20-24 wire sizes, it's possible to use other wire sizes with the 79109-1021 connector. However, you should ensure the wire size is compatible with the connector's terminal design and that the wire insulation is not damaged during insertion. Consult with Molex or a qualified engineer for guidance on using non-recommended wire sizes.
  • To ensure reliable connections and prevent terminal screw loosening, apply a thread-locking compound, such as Loctite, to the screw threads. Additionally, consider using a screw-locking mechanism or a connector with a built-in screw-locking feature.
