Most motion control applications include sensors or other detectors in addition to encoders. Quite often these devices – for example, limit switches, proximity switches, etc. – also have M12 (12 mm) style connectors. Since all the 3-pin, 4-pin, and 5-pin cordsets are compatible with the 5-pin connector on the Accu-Coder®, you can stock fewer cordsets to cover multiple motion control devices, making this option even more cost effective.
Two types of cordsets are available for use with Accu-Coder® encoders: Non-CE and CE (Conformité Européenne). For Non-CE cords, the shield is not connected to the coupling nut on the encoder end of the cable, and it is grounded on the controller end. For CE cordsets the shield is connected to the coupling nut on the encoder end of the cable, and it is also grounded on the controller end, which results in improved noise suppression and immunity. Despite this advantage, EPC recommends that the CE cordset is only used when the application requires it in order to avoid harmful grounding loops. When using a CE cordset take special caution to ensure proper machine bonding and grounding.
