What are the rules for parallel-connection of XS 3-wire inductive, XT capacitive and XU photoelectric detectors?
The relevant products are XS inductive and XT capacitive sensors, and XU photoelectric detectors.
When connected in series, XS and XU products do not generate conducted or radiated electromagnetic phenomena likely to disturb their environment.
Their immunity to electromagnetic disturbance is also compliant with IEC standard 947-5-2.
3-wire sensors can be connected in parallel except in the specific instance of use of a self-inductive load (relay) where a non-return diode is essential.
