The connectors are factory-molded and tested for signal integrity and impedance. Shortening the cable manually risks introducing noise and voids the technical performance specifications. If you require a shorter run, please select the M005 (5m) or M010 (10m) variants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this cable support both analog and digital signals?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes. The AKB337-M020 carries standard 24V DC digital signals and 4-20 mA analog signals. However, ensure that the I\/O module and terminal board pins match the cable's internal pinout configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the benefit of the \"NOS\" (New Old Stock) status?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: NOS indicates the product is 100% brand new and unused, typically held as a spare part.
