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.
