Description
High-Power PCB Screw Terminal Block (Pitch: 16.0mm)
Product Overview
The 16.0mm High-Power PCB Screw Terminal Block is an ultra-rugged, industrial-grade wire-to-board connector engineered engineered specifically for extreme-current paths and thick-gauge industrial main cables. Featuring an ultra-wide 16.0mm pin spacing, this terminal block provides maximum physical separation between adjacent contacts to achieve superior voltage isolation, effectively preventing high-voltage arcing, corona discharge, and surface tracking even in harsh, dusty, or high-pollution environments.
Equipped with a reinforced high-torque rising cage clamp mechanism, it allows technicians to establish robust, gas-tight, and vibration-proof wire terminations directly onto heavy-copper printed circuit boards (PCBs). This makes it an indispensable component for high-capacity industrial power systems, heavy machinery grid distribution, and grid-tie infrastructure where handling large-diameter electrical wires with absolute mechanical security is critical.
Key Features
-
Ultra-Wide 16.0mm High-Voltage Pitch: Features an expansive 16.0mm ($0.630\text{ inch}$) pin spacing to provide exceptional physical and electrical isolation, comfortably meeting strict international clearance and creepage regulatory safety standards for high-voltage industrial machinery.
-
Reinforced High-Torque Rising Cage Clamp: Utilizes a massive internal brass cage clamp that exerts extreme, uniform pressure across the entire wire profile, minimizing contact resistance and preventing loose connections caused by severe thermal expansion or mechanical vibration.
-
Large-Diameter Wire Port: Designed with an oversized wire entry funnel to effortlessly accommodate thick-gauge, heavy-duty solid or stranded electrical cables up to 6 AWG or 8 AWG.
-
Heavy-Duty Industrial Housing: Molded from premium, high-density, glass-fiber reinforced polyamide (UL 94V-0) capable of withstanding extreme continuous heat, structural torque, and harsh industrial environments without warping or fracturing.
