Connector Harting HART Han 3A-gg-M20 (model 19200031443) – rectangular multi-pin industrial connector, M20 gland

The Harting HART Han 3A-gg-M20 is a rectangular multi-pin industrial connector designed for reliable power and signal transmission in demanding environments. The compact Han 3A housing with an M20 cable gland interface provides a space-efficient solution for machine tools, control cabinets and field equipment. Its design focuses on secure mating, straightforward cable entry and mechanical robustness to support long-term operation in industrial installations.

Advantages

The connector combines a compact housing form factor with a standardized M20 gland interface, enabling neat cable routing and easy installation. Robust construction ensures mechanical stability and resistance to vibrations common in industrial machinery. The multi-pin arrangement supports both power and signal conductors in a single rectangular housing, reducing panel space and simplifying wiring. A secure locking mechanism provides reliable mating to prevent accidental disconnection.

Suitable for

• Machine tools and production equipment
• Control cabinets and distribution panels
• Field devices and outdoor enclosures with protected cable entry
• Equipment requiring combined power and signal connections

Key specifications

• Housing type: rectangular Han 3A compact housing
• Cable gland interface: M20 threaded cable entry
• Contact configuration: multi-pin arrangement for power and signals
• Mechanical features: robust metal/plastic housing with locking mechanism for secure mating
• Application environment: industrial use with resistance to vibration and mechanical stress

How to use

Prepare cable ends according to conductor size and insert them through the M20 gland; tighten the gland to ensure strain relief and environmental protection. Mount the connector housing to the panel or device cutout appropriate for Han 3A style rectangular connectors, then terminate conductors on the mating insert or contacts following the manufacturer's contact assignment and torque specifications. Engage the mating halves and secure the locking mechanism to complete the installation. Verify continuity and correct wiring before applying operational voltage.

Recommendations

For reliable long-term performance, use appropriately sized conductors and torque values for terminations, ensure the M20 gland is tightened to provide strain relief and ingress protection, and select compatible mating parts and mounting cutouts designed for Han 3A housings. Periodically inspect connections in high-vibration environments and re-tighten as necessary.
