Technical characteristics Types F, F9, FM and 2F
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
Fitting the crimp contacts
After crimping the wires onto the contacts with the help of a crimping
tool or an automatic crimping machine the contacts should be correctly
oriented and inserted into the cavities of the connector moulding in the
required configuration . They snap into position and are firmly held in
place . A light pull on the wire assures the correct tensile strength of
the contact . When using stranded wires with a gauge below 0 .37 mm²
an insertion tool is necessary .
Removing the crimp contacts
The removal tool is inserted into a slot on the termination side of the
respective crimp cavity . This action compresses the contact retaining
spring therefore the contact can then be easily withdrawn using a
light pull on the wire . This action will cause no damage to the contact/
wire which can be repositioned/refitted as necessary . The drawing
demonstrates the crimp removal procedure (max . 5x) .
