HRS DF1B-2428SCF
Product Overview
The DF1B Series is a 2.5mm pitch connector designed for discrete wire connection, compliant with UL/CSA standards. It features innovative Insulation Displacement (ID) and crimping contact methods, allowing for the mixing of different current capacity cables within a single connector. This design enhances maintainability through replaceable contacts and ensures high reliability by protecting the insulation displacement area within the case. The ID connection process is cost-effective, utilizing existing crimping machines with an applicator change. A potting header option is available for waterproof applications. The series offers broad variations, including single and double row configurations for "Board to Cable" and "In-line" connections, with standard tin and gold plating options.
Key Features:
- Mixed Current Capacity Cables: Combines ID and crimping contacts to accommodate different cable current capacities in one housing.
- Excellent Maintainability: Contacts can be replaced after connection.
- High Reliability: Insulation displacement area is protected by the case.
- Cost-Effective ID Connection: Requires only applicator replacement on existing crimping machines.
- Potting Header Available: Suitable for waterproof applications.
- Broad Variations: Single/double row, "Board to Cable"/"In-line" configurations, tin/gold plating.
Applications:
Business equipment, including copy machines and printers.
