Overview
The A-BL-254DA40-085GSR1 is a board connector from the ASSMANN WSW Components A-BL series. It features 40 contacts arranged in 2 rows with female stamp pin terminals. The connector utilizes a 2.54 mm (0.1 inch) pitch and is designed for right-angle surface mount installation. This component provides a reliable interface for PCB connections, adhering to standard spacing requirements for electronic assembly.
Feature Summary
- Right-angle surface mount configuration for space-efficient PCB integration
- Female stamped pin terminals ensuring secure mating stability
- Dual-row layout accommodating 40 contacts within a compact footprint
Applications
- General-purpose electronic circuit board interconnections
- Industrial control system signal routing
- Consumer electronics internal wiring harnesses
Procurement Notes
Verify the specific manufacturer part number against official ASSMANN WSW documentation to confirm compatibility. Ensure that the right-angle surface mount orientation matches the target PCB design constraints. Cross-reference contact count and pitch specifications with system requirements before procurement to prevent integration errors.
Selection Notes
Select this component when a right-angle female header is required for surface mount applications. The 2.54 mm pitch aligns with standard industry spacing. Consider the 40-contact capacity and dual-row arrangement to determine if it meets the specific I/O density needs of the target electronic assembly without requiring additional connectors.
Part Context
This part belongs to the A-BL series of board connectors manufactured by ASSMANN WSW Components. The series typically includes various contact counts and mounting styles. The A-BL-254DA40-085GSR1 specifically denotes the 40-position variant with right-angle surface mount termination, distinguishing it from through-hole or straight-profile alternatives within the same product family.
Replacement Considerations
Compatible substitutes include other 40-pin, 2-row, right-angle female headers with 2.54 mm pitch from ASSMANN WSW, such as the A-BL-254DA36-085GSR1 or A-BL-254DA38-085GSR1, provided the contact count difference is acceptable for the application.
