1-749656-1 Frequently Asked Questions (FAQs)

  • The recommended torque for the screw terminals is 0.5-0.7 Nm (4.4-6.3 in-lbs) to ensure secure connections.
  • While the connector is designed for industrial applications, it is not specifically rated for outdoor use. However, it can be used in outdoor environments with proper sealing and protection against moisture and environmental factors.
  • It is not recommended to use a wire gauge that is significantly different from the specified range (22-18 AWG) as it may affect the connector's performance and reliability. Consult with TE Connectivity or a qualified engineer for specific guidance.
  • To ensure proper mating and unmating, follow the recommended mating sequence, apply gentle pressure, and avoid forcing the connector. Also, ensure the connector is clean and free of debris before mating.
  • The operating temperature range for the 1-749656-1 connector is -40°C to 105°C (-40°F to 221°F), but this may vary depending on the specific application and environmental conditions.
