J30J 31-Core Female Micro Rectangular Connector – Straight Crimp Wire Type
Product Overview
The J30J Series Micro Rectangular Connectors are designed for high-density, lightweight, and highly reliable interconnection applications. The shell is constructed from aluminum alloy for durability, and the contacts are socket-type, typically crimped with wires ranging from 0.05mm² to 0.15mm². These connectors comply with both GJB2446A and MIL-DTL-83513 standards.
Application Scope:
Ideal for use in aerospace, military, and industrial systems where
space-saving and weight reduction are critical—suitable for
high-reliability signal transmission in dense electrical circuits.
Product Features:
31-pin micro rectangular female connector (J30J Series)
Crimp tail with straight wire exit
Wire range: 0.05mm² to 0.15mm²
Screw-lock installation mechanism
Anti-vibration, lightweight, excellent EMI shielding, and low insertion force
Other pin configurations available: 9, 15, 21, 25, 37, 51, 66, 74, and 100 cores
