Description
2-Pin Pluggable Terminal Block Connector (Pitch: 5.08mm)
Product Overview
The 2-Pin Pluggable Terminal Block Connector Set is a compact, high-reliability modular interface engineered for efficient wire-to-board power and signal routing. The system consists of a 2-position female plug with rugged screw-clamp terminations and a matching 2-position male header designed for through-hole soldering onto printed circuit boards (PCBs).
This pluggable design allows technicians and developers to connect or disconnect a 2-line power supply or signal link instantly without altering individual screw joints. It significantly minimizes downtime during field maintenance, system upgrades, or diagnostic swaps. Molded from flame-retardant polyamide, it ensures optimal mechanical strength and high dielectric isolation for essential hardware connections.
Key Features
-
Time-Saving Pluggable Interface: Enables rapid connect and disconnect functionality for 2 distinct electrical lines simultaneously, streamlining hardware assembly and field maintenance.
-
Heavy-Duty Rising Cage Clamp: Internal nickel-plated brass cage clamps exert even, high-torque pressure across the wire profile, ensuring low contact resistance without tearing fine copper strands.
-
Polarized Keying Alignment: The housing geometries of the male header and female plug are uniquely polarized to eliminate mis-mating and reverse-polarity errors during quick-disconnect cycles.
-
Industry-Standard 5.08mm Pitch: Features standard $0.2\text{ inch}$ pin spacing, fitting cleanly into standard commercial PCB layouts and industrial breakout board grid footprints.
