Send us your technical drawings, samples, or exact panel specifications. We handle full tool/mold fabrication, precision polymer injection molding, and bulk delivery tailored strictly to your technical standards.
From initial spatial requirements and multi-tier structural design to DFM analysis, mold tooling, dielectric testing, and complete sub-assembly—we provide complete custom enclosure solutions ready for distribution.
The Insulating Spacer Block is a precision-molded internal dielectric component designed to provide physical separation, electrical insulation, and cable management within AC contactors, relays, and industrial control equipment. Equipped with extended cylindrical positioning pins and slotted guide comb teeth, it locks internal housing layers in place while routing control wiring securely away from high-voltage arc zones.
Integrated Alignment Post Pins: Features sturdy cylindrical guide pins that insert into contactor housing frames for accurate, slip-free alignment during assembly.
Molded Cable Comb Slots: Designed with parallel retaining teeth along the base to organize, separate, and strain-relieve thin control wires or sensor leads.
Dielectric Phase Barrier: Serves as a physical barrier to increase air clearance and creepage distances between live internal conductors and ground.
High-Strength Thermoplastic Build: Molded from heat-resistant, flame-retardant industrial plastic capable of enduring thermal stress and mechanical vibration.
Compact Standoff Geometry: Rigid rectangular bridge frame provides structural support without adding unnecessary weight or bulk inside the switchgear assembly.
Product Type: Insulating Spacer / Internal Cable Comb Support
Material: Flame-Retardant PA66 / PBT Plastic
Color: Dark Gray
Mounting Style: Pin-Guided Snap / Press Fit
Applications: AC/DC Contactors, Overload Relays, Motor Control Centers, and Switchgear Cabinets
