HA Series Heavy Duty Connector, 16+PE, Surface Mounting, Screw Terminal, Top/Side Entry, 16A/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 simplifies the installation of multi-wire systems. It utilizes a surface mounting base that attaches directly to flat walls. You do not need to cut large panel holes. This 16+PE kit handles complex control circuits with a rating of 16A and 250V. The screw terminal inserts allow you to connect wires easily using a standard screwdriver. No special tools are required. The hood supports top or side cable entry options. A single locking lever keeps the connection secure against vibration.
Note: The product supports multiple thread size options, and customers can choose the specification that matches their installation needs.

- High-density 16+PE configuration rated at 16A 250V.
