ZW-20-11-G-D-538-126

Samtec Inc.'s ZW-20-11-G-D-538-126 establishes new standards in Rectangular Connectors - Board Spacers, Stackers (Board to Board) for medical electronics. This precision-engineered interconnect solution combines biocompatible materials with exceptional signal integrity, making it ideal for diagnostic imaging and patient monitoring equipment.Configurable with 40 positions, this connector family addresses diverse medical device requirements. The scalable architecture supports both low-voltage analog signals and high-speed digital interfaces.The 0.100" (2.54mm) pitch configuration minimizes capacitive coupling between adjacent circuits. This spacing is particularly critical in sensitive biomedical signal acquisition systems.Designed with 2 rows, this connector achieves optimal signal isolation for differential pairs. The symmetrical layout enhances common-mode rejection in low-noise amplifiers.The 0.100" (2.54mm) row spacing effectively reduces crosstalk in multi-channel EEG/ECG applications. This dimension has been validated through clinical-grade EMI testing.With 0.930" (23.622mm) overall pin length, the connector accommodates various medical PCB designs. The precision-machined pins ensure consistent mating depth for reliable signal transmission.The 0.266" (6.756mm) mating post length provides optimal contact force distribution. This design feature is critical for maintaining signal integrity in portable medical devices.Featuring 0.538" (13.665mm) stack height, this solution enables compact medical device packaging. The controlled height tolerance ensures proper alignment in wearable health monitors.The 0.126" (3.200mm) tail length has been optimized for medical PCB assembly. This dimension ensures reliable solder joints while meeting stringent cleanliness requirements.Available in Through Hole variants, the connector supports medical-grade manufacturing processes. The through-hole version features biocompatible solder joints for implantable devices.The Solder termination system has been validated for medical sterilization processes. The solder joint design maintains reliability after repeated autoclave cycles.Employing Gold plating, the contacts achieve exceptional biocompatibility. The proprietary finish formulation meets ISO 10993-1 requirements.The 10.0µin (0.25µm) plating thickness exceeds medical device standards. This specification has been verified through accelerated aging tests.The Black housing material incorporates antimicrobial additives for hospital environments. The USP Class VI certified polymer ensures safety in medical applications.
