ST Series 4 Pin Push Pull Circular Connector for Industrial Automation

PC Series Circular Connector Types and Specifications

ST Series 4-Pin Push-Pull Circular Connector Overview

The ST Series 4-Pin Push-Pull Circular Connector is designed for automation systems, control panels, and machinery requiring fast, reliable connections. Its push-pull mechanism enables tool-free mating and demating, providing speed and security in demanding environments. With 4 pins, it supports power, signal, or combined circuits in a compact interface.

Push-Pull Locking Mechanism

The connector’s push-pull locking mechanism offers:

• Fast, tool-free connection and disconnection, saving assembly and maintenance time
• Automatic locking, preventing accidental disconnection under vibration or movement
• Stable electrical performance across repeated use
• Compact circular form, ideal for space-limited industrial installations

Key Features

• 4-Pin Configuration: Supports power, signal, or mixed circuits in a compact interface.
• Push-Pull Locking Mechanism: Provides secure, repeatable connections and eliminates the need for tools.
• Rugged Industrial Construction: Metal housing and precision contacts resist shock, vibration, and repeated mating cycles.
• Environmental Protection: Designed to withstand dust, moisture, and industrial conditions.
• Space-Saving Circular Design: Suitable for control panels, automation machinery, and sensor networks.
