HA Series Heavy Duty Connector Assembly, 4+PE, Screw Terminal, Cable to Cable, Top/Side Entry, 10A/250V
Introduction:
Heavy-duty connectors (HDC) use strong aluminum or thermoplastic housings to protect against dust, moisture and mechanical stress. They consist of five main components: housing, hood, inserts, contacts and cable glands. Modular and monolithic inserts combine power, signal, data and pneumatic lines in one connector to save space in control cabinets. Flexible cable outlet directions and hoods for large-diameter cables also help with wiring in tight spaces.
The HA series heavy duty connector assembly is designed for reliable cable-to-cable connections. It allows you to extend power lines without mounting to a fixed panel. The kit includes a robust housing with a single locking lever for secure mating. Installation is simple because the inserts use screw terminal technology. You can connect wires using just a standard screwdriver. The system features a 4+PE configuration rated at 10A and 250V. It also comes with a hood offering top or side entry options.
Note: The product supports multiple thread size options, and customers can choose the specification that matches their installation needs.
Key Features:
- Cable-to-cable housing for free-hanging connections.
- Screw terminal inserts need only a screwdriver.
- Single locking lever ensures vibration-proof mating.
- Compact 4+PE configuration rated at 10A 250V.
- Hood supports top or side cable entry.
