Selection Notes

The down-arrow symbol gives an unambiguous jog-down or lower command, keeping the direction clear even where operators do not share a common language. The black bezel with a white symbol reads at a distance against the usual white up-arrow/black bezel pairing of the matching XB5AA3341 head, letting an operator tell the two stations apart by colour as well as graphic. The 1NO contact wires directly into a PLC input or jog-relay coil within its 3 A/240 V AC-15 rating.
