.050" [1.27] SCSI II/III RIGHT ANGLE & VERTICAL PCB MOUNT S2A SERIES Introduction: Adam Tech right angle PCB SCSI II / III connectors are a popular high density interface for many I/O applications requiring a miniature connector. Offered in 20, 26, 28, 40, 50, 68, 80, 100 and 120 positions they are a good choice for high density compact applications. They feature a flat leaf and fork contact design and a one touch, locking receptacle/plug combination. Adam Tech connectors are manufactured with precision stamped contacts offering a choice of contact plating and a wide selection of mating and mounting options. They are ideal for most compact electronic applications. Features: Conforms to SCSI II standards One touch Locking Receptacle and Plug Blade contact with Blanked terminal Industry standard compatibility Durable metal shell design Precision formed bifurcated contacts Variety of Mating and mounting options Mating Connectors: Adam Tech SCSI II / III connectors and all industry standard SCSI II / III connectors.
