The IForce ironless linear motors with rev D hall-effect sensors are RoHS and can be used with up to 24vdc. To determine which board type is used in the coil, check the printing on the cable. Rev D boards are used coils that are marked RoHS and Rev B.
As a reference, Rev C drawing is also included which accepts up to 15vdc.
This change affects only the hall-effect feedback voltage; not the limit or home sensors.
