HA Series Heavy Duty Connector, 3+PE, Screw Terminal, Side-Bulkhead Base, Top/Side Entry Hood, 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 provides a dependable interface for power and signal lines in automated equipment. Rated at 10A and 250V, this 3+PE assembly includes a side-bulkhead base optimized for secure panel integration in tight spaces. The system prioritizes ease of use with screw terminal inserts, allowing technicians to connect wires rapidly using standard tools without crimping. Paired with a hood offering top or side entry flexibility, the connector ensures robust ingress protection and mechanical stability.
Note: The product supports multiple thread size options, and customers can choose the specification that matches their installation needs.
Key Features:
- Reliable 3+PE power interface rated 10A 250V.
- Side-bulkhead base designed for compact panel mounting.
- Screw terminal inserts simplify on-site wiring tasks.
