The 147378-2 is a 20-position SYS50 surface-mount receptacle connector with shielding and without hood, manufactured by TE Connectivity. This connector is designed for high-density interconnect applications requiring electromagnetic shielding to minimize signal interference. The product is reflow solder capable to 260°C, enabling compatibility with modern surface-mount assembly processes. It complies with EU RoHS Directive 2011/65/EU with exemptions and features low halogen content (Br, Cl, F < 900 ppm per homogeneous material), along with BFR/CFR/PVC-free construction. The connector is suitable for applications requiring reliable, shielded signal transmission in compact form factors, particularly in industrial and telecommunications equipment where space constraints and EMI protection are critical considerations.
