Amass XT90S-F3 yellow 2pin female anti-spark power connector with housing, 500VDC, 40/90A *new*

This power connector type is quite popular among battery powered electronics. This connector can accommodate relatively large wire sizes, pass through many amperes and it's as nice and tiny as these high power connectors get. This connector (should be) idiot proof (until world creates a better idiot) and you connect it only one way, every day. To put it in other words the connector is coded (asymmetrical construction) and can only mate one way with the counterpart. Also + and - are indicated on the connector for increased safety and ease of use.

Specialty of this connector is, that it has an internal 5,6Ω series resistor for reducing sparking upon connection

Some use examples for power connectors:

• Battery connectors
• Power supply connectors
• Motor connectors
• Connecting high current devices with various controllers

Connector technical details:

• Max operating voltage:
  • 500VDC
• Max rated constant current:
  • 40A
• Max momentary current:
  • 90A
• Max compatible wire size:
  • 6mm² (10AWG)
• Connector type:
  • 2pin male coded power connector with 5,6Ω series resistor on the + connection.
    • Upon mating the connector, the + wire makes first connection to the load through the internal 5,6Ω resistor in order to limit the inrush current, thus reducing sparking and possibility to weld contacts... Or avoid breaking something else with high inrush current when charging up the appliances capacitors. After pushing the connector fully in the series resistor is bypassed  and all works normally.
• Connection method:
