Additional Details

This connector is part of Hirose's BM20 series, known for its miniaturization and robust design. The 0.8mm pitch allows for a high density of connections within a small footprint. The 0.4mm mated height contributes to the overall thin profile of electronic devices. The connector is designed for surface mount technology (SMT), which enables automated assembly and enhances manufacturing efficiency. The housing material is typically a high-performance plastic that provides excellent insulation and mechanical strength. The contacts are usually gold-plated to ensure reliable electrical contact and resistance to corrosion. The (53) likely refers to a specific packaging or manufacturing detail. Detailed specifications regarding current rating, voltage rating, operating temperature range, and mating force can be found in the Hirose datasheet for this part number. Correct reflow soldering profiles are critical for reliable assembly.
