Screw connection of the alternative FE connection
•
Screw: M5 × 12
•
Screw head: hexagon with slot, width across flats WAF 8
•
Tightening torque: 3.5 Nm to 5.0 Nm
Suitable cable lugs
•
Forked cable lug or ring cable lug
•
Width ≤ 10 mm

Ethernet for PROFINET PROFIsafe, data output, configuration and diagnostics (XF1, XF2)
microScan3 – PROFINET (RJ45)
On the device side, Ethernet and PROFINET are connected via RJ45 female connectors
for push-pull connectors. There is a network switch in the safety laser scanner which
connects the two female connectors. The two female connectors therefore have the
same function.
