IEEE-488 GPIB / IEC 625 cable assembly

Cable assembly ( colour grey) to IEEE-488 GPIB /IEC 625 . Designed to facilitate rapid interconnection up up to 15 programmable instruments ( in star or daisy chain configuration ) or control equipments equipped with IEEE-488 GPIB IEC 625 ( also known as HPIB ) communication link capable of , talking ,listening , talking and listening and or controlling . Each end of the assembly consists of a back to back 24-way male and female connector (rack and panel type ) with captive locking screws . The cable contains 24 conductors of which 16 are used for signal lines and the balance used for logic ground returns and overall sheild . Lines DAV , NRFD , NDAC, IFC , SRQ and ATN lines are each twisted together with a ground wire to form twisted pairs as detailed in the connector contact assignment table show below .
Available in 1m and 2m lengths.
Voltage rating 200V d.c. Current rating 5A per contact . Contact resitance <10M ohm . Contact material , gold over copper .
