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.
