The 15 A resistive rating at 250 VAC covers standard control-panel switching duty, and the asymmetric inrush envelope — up to 30 A on the NC contact versus up to 15 A on the NO contact — is the figure that matters when the switch lands on a solenoid, transformer, or incandescent lamp load rather than a resistive heater. ## Contact life and mechanical duty envelope The 20 operations/minute minimum figure published for the series is the floor below which the snap-action mechanism can stick on lightly oiled or sluggish actuators; it is a sizing constraint on slow-moving damped cams, not a rating to design toward. ## Panel mounting and solder termination The switch drops into a 4.2 mm mounting hole and ships with solder terminals, which fits the traditional back-of-panel wiring pattern on machine frames and junction boxes rather than the plug-in quick-disconnect bodies used on modular conveyor sections.","metaTitle":"Omron Z-15HW400 Limit Switch, SPDT, 15 A, 250 VAC","metaDescription":"Omron Z-15HW400 Z-series snap-action limit switch, SPDT, 15 A at 250 VAC, solder terminal.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Limit Switches"],"specifications":{"title":"Z-15HW400","Rated load":"15 A at 250 VAC","Switch type":"SPDT","description":"Z Series General Purpose Basic Switch|The most popular snap action limit switch","Terminal type":"Solder terminal","Inrush current":"Up to 30 A at NC, Up to 15 A at NO","lifecycle_stage":"current","Mounting hole size":"4.2 mm","Mechanical operations":"240 operations/minute max.","Electrical operations minimum":"500,000 operations","Mechanical operations minimums":"20 operations/minute max."}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/26be32fe58e32df2a0d0ad37fe87e994.pdf","sourceUrl":"https://automation.omron.com/en/us/products/family/Z-15"},"ai":{"faq":[{"question":"Where can I buy the Z-15HW400 and how do I get a price?","answer":"Submit the required quantity and any traceability or documentation requirements with the request so the quote reflects the actual BOM line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/Z-15HW400","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/Z-15HW400 when reusing this data.
