Hirschmann ST Series 5-Pin Rectangular Industrial Connectors

The Hirschmann ST Series 5-pin + PE rectangular connectors deliver a compact and versatile solution for power distribution and control wiring in machine building and control-panel applications. Engineered for durability, safety, and easy installation, these connectors are an ideal choice when you need dependable performance in demanding industrial or building-automation environments.

Key Features & Technical Strengths

• Trusted performance: The ST-Series 5-pin connectors handle most standard industrial voltages, delivering stable power or signal transmission for controls, lighting, small motors, sensors, or building automation components.
• 5 + Protective Earth (PE) pinout: The 5-pin format plus dedicated ground pin supports proper phase-neutral-earth wiring, ensuring safe installations and compliance with industrial wiring standards.
• Robust, field-attachable design for on-site wiring: ST-Series connectors are available as field-attachable cable plugs (and matching socket / panel-mount versions), making them suitable for flexible wiring, custom cable assembly, or rapid maintenance.
• Durable housing and contacts: With glass-fiber reinforced polyamide housing and copper-zinc contacts (silver-plated), ST connectors offer low contact resistance (≤ 10 mΩ) and reliable mating even under vibration or mechanical stress.
• Environmental protection & broad temperature tolerance: Standard IP54 rating (dust-protected and splash-resistant) and operating temperature range from –30 °C to +90 °C make them suitable for factory floors, outdoor installations, or control cabinets exposed to temperature variation.

Common Applications

• Power and control wiring for lighting, small motors, actuators, or pumps in industrial machinery, conveyor systems, or tooling.
• Wiring for building automation components (ex- HVAC, pumps) where a grounded, 5-wire connection is needed.
• Control panels or distribution boards in factories or warehouses requiring secure, sealed connections.
• Field-serviceable equipment and modular machines where on-site installation, maintenance, or reconfiguration makes field-attachable connectors advantageous.
