Dear Johannes,
Thank you for your reply and the links.
Would this kind work as well: Intertec ITS-LS-4035-D-24VDC Hubmagnet drückend 8 N 75 N 24 V/DC 12.7 W kaufen
It promises 8N, using 12,7W, which means 12 of them could be triggered at the same time by the 160W supply, or am I missing something?
Or this one, 1kg, 16W (=no more than 10 at the time, right?)… Intertec ITS-LS-5852-D-24VDC Hubmagnet drückend 5 N/mm 85 N/mm 24 V/DC 16 W kaufen
(Why does it ‘only’ have 5N if it’s twice the size?)
(or this one, who seems more practical: Intertec ITS-LZ-3263-Z-24VDC Hubmagnet ziehend 30 N 59 N 24 V/DC 12.96 W kaufen)
Best
