W22 4-Pin Industrial Socket with 3.5mm Pitch Terminal Block for Industrial Automation Controls & PLC Power Distribution

This product is a ruggedized, industrial-grade W22 Type 4-Pin Electrical Power Socket paired with a 3.5mm Pitch Terminal Block Connector System. Designed as a high-density wire-to-board power delivery assembly, it pairs a heavy-wall vertical socket base with a secure pluggable terminal block. This combination enables field engineers to seamlessly connect bare discrete copper wires directly into a highly secure, pluggable mating matrix without requiring expensive pre-crimped wire harness tooling.

The W22 socket and 3.5mm terminal block system is heavily optimized for localized control loops and power input panels. It is the premier choice for Programmable Logic Controllers (PLCs), Industrial Automation Control Cabinets, CNC machinery power blocks, and smart HVAC control modules. It is equally ideal for Renewable Energy Inverter Systems, Din-Rail relay racks, and industrial power distribution boxes where standard low-power 2.54mm pin headers cannot satisfy strict field-wiring gauge and high-voltage safety profiles.

Key Features

• Pluggable terminal blocks provide a secure, gas-tight wire grasp that entirely eliminates accidental pull-outs.
• The 3.5mm compact footprint safely routes high continuous current loads up to 10A within minimal PCB spaces.
• Heavy-wall UL94V-0 flame-retardant housing creates deep isolated cavities to block high-voltage jumping.
• Quick-disconnect pluggable architecture enables rapid module swaps and field wiring upgrades without soldering.
• Accepts a flexible spectrum of discrete solid or stranded field wires from 16 to 28 AWG seamlessly.
