Gocator 3210A or B, 3506B: 24 VDC Operation and Cordset Length

Although LMI recommends operating Gocator 3210A, 3210B, and 3506B at 48 VDC to take full advantage of their capabilities, these sensors can operate when connected to a 24 VDC power supply. This may sometimes be necessary, for example, because of local regulations. However, when running these sensors with a 24 VDC power supply, the projector intensity is reduced and as a result, you may need to increase exposure time with darker targets to compensate for the reduced projector intensity. Gocator 3506A can also run at 24 VDC but is not subject to these limitations. For information on setting exposure, as well as the impact of running the sensor at 24 VDC on projector intensity, see Gocator 3210A or B, 3506B on 24 VDC.

Note that because projector intensity decreases with longer cordsets (caused by the increased resistance and higher current), if limiting exposure time is important, try to limit the length of the cordset.

Finally, note that if you run these sensors at 24 VDC, you must specify this voltage and the cordset length in the web interface. For more information, see Configuring Power.
