87978-0021 Frequently Asked Questions (FAQs)

  • The recommended torque for the screw terminals is 0.5-1.5 Nm (4.4-13.3 in-lbs). It's essential to follow this torque specification to ensure reliable connections and prevent damage to the connector.
  • Yes, the 87978-0021 connector is designed to withstand vibrations and can be used in applications with moderate to high vibration levels. However, it's essential to follow proper mounting and installation procedures to ensure the connector remains secure.
  • The 87978-0021 connector has a IP67 rating, which means it's protected against dust and water ingress. However, it's not designed for extreme outdoor or harsh environment applications. If you need a connector for such applications, consider using a connector with a higher IP rating or additional environmental protection.
  • While the datasheet recommends using AWG 20-24 wires, you can use other wire sizes with caution. However, using smaller or larger wires may affect the connector's performance, reliability, and durability. Consult with Molex or a qualified engineer to determine the suitability of alternative wire sizes.
  • The 87978-0021 connector has an operating temperature range of -40°C to 105°C (-40°F to 221°F). Exceeding this temperature range may affect the connector's performance, reliability, and lifespan.
