Labor-saving Pressure Welding Spring-lock Male Connector

  • For Signal
  • Connection in Boards
  • Printer
  • Pressure Welding
  • Gold Plated

● Female connectors made entirely with plastic that allow batch pressure welding for electric wire connection. It can be used separately for both relay and panel mounting.

· It cannot be connected with the screw lock model. (due to different lock system)
· Due to the wires being connected by pressure welding, use manufacturer-specified pressure weld tools or the simple pressure weld tools available
at Misumi.
· If the wires were connected using the simple tools available from Misumi, use after thoroughly checking the pressure welding.

· No abnormalities such as damage etc. on the connector
In compliance with MIL-STD-202 test method condition 204 A, simple vibration with smaller amplitude, either the total amplitude of 1.52 mm from 10 Hz to 500 Hz or 10 G (gravity units) is applied to each for 3 hours in mutually perpendicular 3-axis direction.
Impact Resistance No cracks in the connector or abnormalities such as loosening in breakable parts Impact of 50 G with duration 11 msec is applied to the coupled connector in mutually perpendicular axis direction.
Insertion and Removal Durability No mechanical damage Perform insertion and removal 500 times at speeds not exceeding 500 times per 1 hour.

Environmental Properties

Item Characteristics Conditions
Temperature Resistance There should be no physical damage or obstacle when inserting or removing the connector Repeatedly expose to temperatures +85°C and -55°C for 30 minutes 5 times each. However, do not expose to room temperature for 5 minutes or more when moving from low temperature to high and from high temperature to low.
Humidity Resistance · There should be no mechanical damages
· Voltage Resistance 300 VAC 1 minute
Perform 96-hour humidity test with the connector detached in compliance with MIL-STD-202 test method 103 B.
