HE Series Heavy Duty Connector, 48+PE, Surface Mounting, Screw Terminal, Top/Side Entry, 16A/500V
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 HE series heavy duty connector simplifies installing massive wiring systems. It utilizes a surface mounting base that attaches directly to flat walls. This eliminates the need for cutting large panel holes. The assembly achieves a high-density 48+PE configuration by combining two 24-pin inserts side by side. Wiring is easy because of the screw terminal technology. You can connect all lines quickly using a standard screwdriver. It handles industrial loads rated at 16A and 500V.
Note: The product supports multiple thread size options, and customers can choose the specification that matches their installation needs.
Key Features:
- Surface mounting base installs without panel cutouts.
- Combines two 24-pin inserts for 48+PE connection.
- Rated at 16A 500V for high-density wiring.
- Screw terminal inserts require no crimping tools.
- Hood design offers top or side cable entry.
