HA Series Heavy Duty Connector, 3+PE, Screw Terminal, Surface Mounting, 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.
Heavy-duty connectors offer crimp, screw, spring and push-in terminals for simple installation. The housing sizes follow industry standards and include 3A, 10A, 16A, 32A, 6B, 10B, 16B, 24B, 32B and 48B options. The connectors support up to 216 contacts and up to 108 circuits at 10A per pole. For high-current applications, heavy-duty connectors offer inserts rated from 80A to 200A. These high-current inserts typically have fewer poles, usually one to three, to provide sufficient conductor cross-section and heat dissipation capacity.
Key Features:
- Screw Terminal: Simple, strong connection via screwdriver; no crimping tools needed.
- Surface Mounting Housing Base: Direct flat-surface installation without panel cutouts.
- Top Cable Entry Interface: Vertical design for straight, overhead cable routing.
- Single Locking Lever: Quick locking mechanism reduces maintenance downtime.
