Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a SCHLEIFRING part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 2 series from our supply network are the closest match on published figures.
Hybrid units combining fibre optic channels with power and signal circuits, used on electro-optical pod systems.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
