Overview
The AW140-EG-Z28C1 is a rectangular connector header from the AW140 series, manufactured by Assmann WSW Components. It features 28 positions with a 0.100 inch (2.54 mm) pitch. Designed for through-hole mounting, this component utilizes gold-plated contacts to ensure reliable signal transmission. The unit is constructed with a polybutylene terephthalate housing and is rated for 250V operation within a temperature range of -40°C to 105°C.
Feature Summary
- Through-hole mounting configuration for secure PCB integration
- Gold-plated contact surfaces for enhanced conductivity and corrosion resistance
- Polybutylene terephthalate housing material providing thermal stability
Applications
- Board-to-board interconnections
- General electronic circuit assembly
- Industrial control system wiring
Procurement Notes
Verify that the suffix 'Z' denotes the specific tin-plated variant rather than the standard gold-plated version found in other AW140 models. Confirm the 28-position count matches the design requirements. Ensure the 2.54mm pitch aligns with the target PCB footprint. Check RoHS compliance status before finalizing procurement orders.
Selection Notes
Select this part when a 28-position male header is required for vertical board-to-board connections. Compare against AW140-EG-G28C1 if gold plating is preferred over tin. Ensure the 250V rating and 3A current capacity meet the application's electrical demands. Verify that the 2.31mm tail pin length fits the available board thickness constraints.
Part Context
This component belongs to the AW140 series of rectangular connectors. It serves as a male receptacle designed to mate with corresponding female sockets. The series offers various position counts and plating options to support diverse electronic assembly needs across consumer and industrial hardware sectors.
