we are planing a control cabinet for a plant, where three cryogenic hall sensors HGCA-3020 will be used. According to our client, these sensors will have a 121 DC constant current source. It is my first time working with these devices and I would just like a confirmation that this actually works. Is it right that one current source can be used for the three sensors in parallel? The sensor operates with a nominal control current of 100mA, which is the maximum the current source can provide.

Hello M. Romero,
We have not tested wiring more than one sensor to a single current source, however, we do believe it should work. To do the actual wiring, the current leads for the three sensors will need to be wired in series instead of parallel as you indicated. This will ensure that 100mA flows through each sensor where in parallel, the current would be divided between the three sensors.
Let me know if you need additional information regarding the wiring connections.
