3-1478978-0 Frequently Asked Questions (FAQs)

• What is the recommended torque value for the screw terminals?
  The recommended torque value 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.
• Can I use this connector in high-vibration applications?
  Yes, the 3-1478978-0 connector is designed to withstand vibrations and is suitable for use in applications with moderate to high vibration levels. However, it's essential to ensure proper mounting and secure the connector to prevent damage or disconnection.
• Is this connector suitable for outdoor use?
  The 3-1478978-0 connector has a rating of IP20, which means it provides some protection against solid objects and fingers, but it's not fully sealed against moisture or water. For outdoor use, it's recommended to use additional protection, such as a waterproof enclosure or conformal coating, to ensure reliability.
• Can I use this connector with wire sizes other than the recommended AWG 20-24?
  While the datasheet recommends using AWG 20-24 wire, it's possible to use other wire sizes with some limitations. However, using smaller or larger wire sizes may affect the connector's performance, reliability, and durability. It's essential to consult with TE Connectivity or a qualified engineer to determine the feasibility of using alternative wire sizes.
• What is the operating temperature range for this connector?
  The 3-1478978-0 connector has an operating temperature range of -40°C to 105°C (-40°F to 221°F). It's essential to ensure that the connector is used within this temperature range to maintain its performance and reliability.
