The unit measures 36 mm wide by 36 mm tall by 28 mm long, which matches the standard NX option-board footprint and lets it share a slot row with other NX1W slices without trimming the DIN layout. Termination is via a plug connector and the housing is plastic, so field wiring is quick-disconnect rather than hard-wired; swap-out on a live panel stays a screwdriver-light job. ## Operating envelope Operating temperature runs from 0 °C to 55 °C, which is the standard NX option-board ambient and sets the cabinet ventilation budget for any sealed enclosure. Because the slice is plastic-housed and plug-terminated, derating against the 55 °C ceiling is set by Omron's standard NX thermal curve rather than by a separate heat-sink spec for this part. ## Not a drop-in for DAB21V The NX1W-CIF11 shares the 36 mm by 36 mm by 28 mm option-board footprint but is a communication expansion board for RS-485/RS-422, not an analogue I/O slice, so it sits next to an MAB221 rather than in place of it. For a stocked spare or a panel build, the order code is the one to specify against the BOM and quote to order through an RFQ; the shared NX1W footprint means any standard NX option-board row in the cabinet will accept it without mechanical rework.","metaTitle":"Omron NX1W-MAB221 Analogue Input Module, 36 mm","metaDescription":"Omron NX1W-MAB221 analogue input option module for the Sysmac NX Series PLCs. 36 mm wide, active production, quoted to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Width":"36 mm","Height":"36 mm","Length":"28 mm","Suitable for":"Sysmac NX Series PLCs","Accessory Type":"Analogue Input Module","lifecycle_stage":"current","Termination Type":"Plug","Accessory Material":"Plastic","Operating Temperature Max.":"55 °C","Operating Temperature Min.":"0 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$135.89 – $276.91","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/NX1W-MAB221/alternatives.json"},"ai":{"faq":[{"question":"When sourcing NX1W-MAB221, what's the closest functional second-source — NX1W-DAB21V?","answer":"NX1W-DAB21V is not a functional second source.
