.050" [1.27] SCSI II/III
RIGHT ANGLE AND VERTICAL PCB MOUNT
Adam Technologies, Inc.
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. These 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 contacts
Variety of Mating and mounting options
MATING CONNECTORS:
Adam Tech SCSI II / III connectors and all industry standard
