Technical characteristics piggyback connectors
Current carrying capacity
The current carrying capacity is limited by maximum temperature of
materials for inserts and contacts including terminals . The current
capacity curve is valid for continuous, non interrupted current loaded
contacts of connectors when simultaneous power on all contacts is
given, without exceeding the maximum temperature .
Control and test procedures according to DIN IEC 60 512
Piggyback connectors for interfacing with
female connectors with wrap posts 1 x 1 mm
The problem of interfacing systems designed for the distribution
or collection of electronic signals can be overcome by the use of
piggyback connectors . Designed to be mounted on the rear of
DIN 41 612 type wire wrap female connectors (1 x 1 mm posts)
these piggyback elements can be used to terminate input and
output cables .
Distance fixing brackets are fitted to provide either a latching or
screw fixing facility over the two level wire wrap plane .
The female crimp contacts used in these versions are designed
for 1 x 1 mm posts .
After crimping they can be easily inserted into the chambers of the
connector body with the aid of an insertion tool . Insertion errors
can be simply rectified with the use of a removal tool .
2 and 3 row piggyback connectors can be mounted in shell
housings C and open hood G . Security is provided by either
latches or screws to the distance fixing brackets .
Number of contacts 16, 32, 48
Working current 6 A max .
