Overview of HE Series Heavy-Duty Connectors
The HE Series Heavy-Duty Connectors are FPIC’s standard rectangular connector solution for industrial applications requiring higher pin density, stable current transmission, and reliable mechanical performance. The series is widely used in automation equipment, power distribution systems, and industrial control cabinets.
Compared with HA Series, the HE Series focuses on higher contact density under a 16A current class, making it suitable for applications where multiple power and signal circuits need to be integrated within a compact connector interface.
Modular Structure & Configuration Logic
HE Series connectors adopt a modular structure, allowing flexible configuration through the selection of housings, inserts, contacts, and termination methods. This modular design simplifies system wiring, maintenance, and future expansion.
Connector structure includes:
- Housing (hood and base)
- Insert (male and female)
- Contacts
- Termination and locking accessories
HE Series Configuration Options
1.Housing Options
HE Series connectors use robust rectangular metal housings made of die-cast aluminum alloy with corrosion-resistant surface treatment, suitable for harsh industrial environments.
Key options:
- Top entry and side entry housings
- Panel-mount and bulkhead-mount bases
- Secure installation for control cabinets and enclosures
2.Insert Types & Pin Counts
HE Series inserts are designed for 16A rated current and support higher contact density compared with HA Series.
Available pin counts:
- 6, 10, 16, 24, 32 (2×16), 48 (2×24) + PE
These configurations allow efficient integration of multiple circuits within one connector.
3.Contacts, Termination & Locking
Contacts are manufactured from high-quality copper alloy to ensure stable electrical performance and long service life.
Termination methods:
- Screw termination
- Crimp termination
- Cage clamp termination
- Spring termination (including quick-connect options)
Locking system:
Lever-type locking mechanism ensures secure mating, vibration resistance, and protection against accidental disconnection.
Electrical & Mechanical Performance
HE Series Heavy-Duty Connectors are designed and tested in accordance with DIN EN 60664 and DIN EN 61984, ensuring safe and reliable operation in industrial environments with pollution degree 3.
These parameters make HE Series connectors suitable for continuous operation in demanding industrial systems.
Typical Applications
- Industrial automation systems
- Power distribution and control cabinets
- Servo drives and motor control systems
