Sub-Micro plug connectors with 1/2" female conduit connection are made to DIN 43650 and ISO 4400 industry standards. These connectors offer distinct advantages over "hardwired" connections with their built in screw terminals and modular plug (unplug) design. This DIN plug will replace the existing 5610C series auxiliary switch (open/close confirmation) output plug and/or the modulating plug. Plug rated IP65 and NEMA 4 for weatherproof applications. Used where 1/2" conduit connection is desired. Maximum wire size 20 gauge.
