Industrial rectangular connector Han 5 Mod bu-ES 16A by Harting, model 09 14 005 2716

Harting Han 5 Mod bu-ES 16A is an industrial rectangular connector engineered for reliable power and signal transmission in machinery, control cabinets and automation equipment. The Han 5 frame accepts modular inserts and the bu-ES variant is rated for 16 A, offering a compact interface for mixed electrical contacts. The design emphasizes robust electrical contact, secure mechanical coupling and compatibility with industrial mounting arrangements.

Advantages

This connector provides stable electrical performance under continuous operation and repeated mating cycles, with materials and contact technology selected for wear resistance. Its rectangular housing enables space-efficient panel and cable installations while maintaining mechanical retention and environmental protection suitable for industrial use. The modular concept allows combination of signal and power contacts in a single frame, reducing wiring complexity and panel footprint.

Suitable for

• Control cabinets and distribution panels
• Factory automation and production machinery
• Industrial drives and motor control systems
• Test rigs and measurement equipment
• Power and signal interfaces in modular assemblies

Key specifications

• Connector type: rectangular industrial connector, modular insert capable
• Current rating: 16 A per designated contact type
• Contact configuration: modular mix of power and signal contacts (frame for inserts)
• Mounting: panel cut-out and/or cable hood coupling with mechanical latching
• Contact materials and plating: conductive metal contacts with corrosion-resistant finish for reliable conductivity
• Operating environment: designed for industrial indoor use; suitable for control cabinet and machinery environments
• Mechanical durability: designed for repeated mating and unmating cycles common in maintenance operations

How to use

Install the Han 5 frame into the appropriate panel cut-out or mating hood and secure it using the recommended mounting hardware. Select and assemble the modular inserts that match required power and signal contact types, then insert them into the frame according to the manufacturer’s assembly guidance. Terminate wires on the insert contacts using the specified connection method (crimp, screw or solder as applicable), ensure proper wire routing and strain relief, then mate the connector halves until the mechanical latch engages to establish electrical connections.

Recommendations

Follow Harting’s assembly instructions and torque values for contact terminations to ensure rated current performance. Verify contact seating and locking after assembly and perform routine inspections in dusty or humid environments. Use compatible mating hoods and gaskets where required to maintain ingress protection and to reduce risk of contamination or mechanical stress.
