Overview of HEE Series Heavy-Duty Connectors
The HEE Series Heavy-Duty Connectors are FPIC’s high-density rectangular connector solution designed for industrial applications where space is limited and multiple circuits must be integrated within a compact connector interface.
Compared with HE Series, the HEE Series provides significantly higher contact density while maintaining a 16A current rating, making it ideal for advanced automation systems, compact control cabinets, and equipment requiring dense signal and power distribution.
Modular Structure & High-Density Design Concept
HEE Series connectors adopt a modular structure similar to other heavy-duty connector families, while optimizing insert layout to achieve higher contact density without compromising electrical or mechanical reliability.
Connector structure includes:
- Housing (hood and base)
- High-density inserts (male and female)
- Contacts
- Termination and locking accessories
HEE Series Configuration Options
1.Housing Options
HEE Series connectors use rectangular metal housings made of die-cast aluminum alloy with corrosion-resistant surface treatment, suitable for harsh industrial environments.
Available options:
- Top entry and side entry housings
- Panel-mount and bulkhead-mount bases
- Secure mounting in compact control cabinets and enclosures
2.High-Density Inserts & Pin Counts
HEE Series inserts are designed for high contact density under a 16A current class, enabling more circuits within a limited installation space.
Available pin counts:
- 10, 18, 32, 40, 46, 64 (2×32), 92 (2×46) + PE
These configurations allow efficient integration of complex signal and power wiring in compact industrial systems.
3.Contacts, Termination & Locking
Contacts are manufactured from high-quality copper alloy to ensure stable conductivity and long service life, even in high-density configurations.
Termination methods:
- Crimp termination
- Cage clamp termination
- Spring termination (including quick-connect options)
Locking system:
Lever-type locking mechanism ensures secure mating, vibration resistance, and reliable operation in industrial environments.
Electrical & Mechanical Performance
HEE Series Heavy-Duty Connectors are designed and tested according to DIN EN 60664 and DIN EN 61984, ensuring reliable performance in industrial environments with pollution degree 3.
These characteristics ensure safe and stable operation even in high-density connector layouts.
Typical Applications
- Compact industrial automation systems
- High-density control cabinets
- Robotics and motion control equipment
- Servo drives and I/O modules
- Advanced manufacturing and production lines
