HDAS Series Connectors
Contact:
Description:
Amphenol reduces the pitch and increases the density of contacts with the HDAS range. With its robust and simple design, high density and high performance in harsh environments, HDAS rectangular connectors are the right high-density PCB connector when installation, cost and reliability must be considered.
Features & Benefits:
Key Features:
- 7 sizes from 3 to 5 rows, 50 to 253 signal contacts
- 4.5A per signal contact / DWV: 750 Vrms
- High density: 1.905 [.075] staggered grid
- Press fit solderless attachment technology available - Lateral rails to protect male pins from external damage
Technical Information:
- Cost effective rugged connector for harsh environments
- Monolithic high-density PCB interconnect
- High pin counts up to 253 contacts per connector
- Designed for severe mechanical environments
- High temperature (LCP material) & vibration levels
- Mezzanine or right angle board to board connection
