Edgeboard connector VISHAY EBT156-15B2W with chamfered lead-ins and reinforced nylon polarizing key
Product Overview
The Vishay Dale EBT156 series offers single readout edgeboard connectors designed for 0.062" (1.57 mm) printed circuit boards. These connectors feature a 0.156" (3.96 mm) contact center spacing and are available with various termination options including dip solder, eyelet, and Wire Wrap. Modified tuning fork contacts with chamfered lead-ins ensure reduced wear on PCB contacts while maintaining contact pressure and wiping action. The design incorporates protected entry for easy card insertion and alignment, preventing contact damage from warped boards. Polarization options are available, either on or between contact positions, with a reinforced nylon polarizing key for secure installation. These connectors are suitable for applications requiring robust and reliable edgeboard connections.
