M20-7822246

Overview

The Harwin M20-7822246 is a 22-position double in-line (DIL) socket connector from the M20 series, designed for board-to-board applications. It features a 2.54 mm pitch and utilizes vertical through-hole termination for PCB mounting. The housing is constructed from high-temperature liquid crystal polymer rated UL94V-0, ensuring compatibility with surface mount reflow processes. Contacts are made of bronze with nickel plating and tin overplating to provide durable electrical connections. This component supports a current rating of 12A and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Vertical through-hole design optimized for board-to-board connectivity
• High-temperature liquid crystal polymer housing compatible with SMT reflow profiles
• Dual-beam contact structure for improved electrical connection reliability

Applications

• Board-to-board interconnections in industrial electronics
