It belongs to the NX I/O family and pairs with other NX slices on the same backplane, which is how an integrator stacks encoder, digital, and analog cards next to a Sysmac NJ/NX controller without re-engineering the bus. Approvals on the agency line are CE, cULus, C-Tick, KC, Lloyd, and NK, so the same SKU can ship into CE-marked machinery, North American panels, Korean installations, and Lloyd/NK-classed marine systems without a regional swap. Termination style is the spring-cage variant of the NX family, so wiring practice is consistent with the rest of the NX I/O line — strip length and ferrule rules are governed by the family specification rather than this single card. ## Where this class of card lives on a machine An incremental encoder input module reads a pulse train from a rotary or linear encoder and turns it into position and speed data the controller can use — the NX-EC0122 is the slice that closes that loop for one axis on an NX backplane. The NX-series family is the I/O tier built around Omron's Sysmac automation platform, which is where the encoder data feeds motion or position control blocks without going through a separate counter card.","metaTitle":"Omron NX-EC0122 Encoder Input Module, 1 Ch, 24V","metaDescription":"Omron NX-EC0122 active NX-series incremental encoder input module, 1 digital channel, 24V PNP, DIN-rail, spring terminal, 0 to 55 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Input Modules"],"specifications":{"Type":"Input Module","Series":"NX","Weight":"0.154 lb (69.85 g)","Package":"Bulk","Mounting Type":"DIN Rail","Approval Agency":"CE, cULus, C-Tick, KC, Lloyd, NK","lifecycle_stage":"current","Termination Style":"Spring Terminal","Operating Temperature":"0°C~55°C","Number of Inputs and Type":"1 - Digital","For Use With/Related Products":"NX Series"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$162.56","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/NX-EC0122/alternatives.json"},"ai":{"faq":[{"question":"What is the listed type and series for the NX-EC0122?","answer":"The NX-EC0122 is listed as an Input Module on the NX series, specifically an incremental encoder input module with one digital channel at PNP 24 V."},{"question":"What is the closest functional alternative in the NX encoder line?","answer":"The NX-EC0222 is the closest same-footprint alternative — same 0.154 lb (69.85 g) housing and same spring-cage termination, but with two digital inputs instead of one, so it is the right swap when an extra encoder channel is needed on the same DIN rail run."},{"question":"What compliance marks ship with the NX-EC0122?","answer":"The agency line is CE, cULus, C-Tick, KC, Lloyd, and NK, which covers CE-marked machinery, North American panels, Korean installations, and Lloyd/NK-classed marine systems from the same SKU."},{"question":"What is the operating temperature window for the NX-EC0122?","answer":"The slice is rated 0 °C to 55 °C operating ambient; outside that window the NX system thermal curve governs derating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/NX-EC0122","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/NX-EC0122 when reusing this data.
