The new pin and socket housings FL3... ideally meet the requirements of modern robot technology for tool-changing systems with
regard to flat construction, ease of installation and service-friendly handling. They are provided with plug-fitting connecting parts, as a result of
which the contact inserts are interchangeable. The connecting leads remain connected during the changing operation. In the 24-, 27- and 36-pole versions
the contact inserts are also interchangeable, but the contacts must be removed from the contact mounts. All FL3 pin and socket casings are IP65 when plugged,
and longitudinally waterproof in their unplugged condition.
