{"product_id":"d4n-4b20r-b0h3z4dpf8","title":"D4N Series Limit Switch D4N-4B20R Roller\/Plunger Actuator","description":"\u003cp\u003eThis listing is for a D4N-4B20R limit switch from the D4N family, supplied as a single unit. The D4N family uses compact chassis-mount bodies with roller or plunger actuator heads for reliable position detection and machine limit signaling. Distributor and supplier references show D4N-series variants with mechanical life ratings around 1,000,000 operations and family electrical ratings reported up to 10 A (AC) and 2.5 A (DC) for comparable submodels; contact arrangement and exact electrical ratings vary by specific D4N submodel. Before installation, compare mounting holes, actuator style (roller\/plunger), terminal type, and the printed model code on the part to ensure correct fit and contact configuration. If precise electrical or dimensional specifications are required, consult the D4N-4B20R datasheet or the seller for the exact submodel details.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFits D4N series applications - select the D4N-4B20R variant for roller\/plunger-style actuator fit; verify printed part code before installation.\u003c\/li\u003e\n\u003cli\u003eMiniature chassis-mount limit switch for position sensing and machine limit detection in automation equipment.\u003c\/li\u003e\n\u003cli\u003eTypical D4N family electrical capability noted on distributor listings (example: up to 10 A AC, 2.5 A DC on some submodels); confirm exact current\/voltage and contact arrangement for D4N-4B20R from the datasheet.\u003c\/li\u003e\n\u003cli\u003eDurable mechanical performance documented for D4N family (mechanical life commonly listed as 1,000,000 operations minimum on supplier pages); vibration and shock ratings vary by submodel.\u003c\/li\u003e\n\u003cli\u003eIncludes: one limit switch (D4N-4B20R) - confirm terminal type and contact configuration match your equipment prior to ordering.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AII","offers":[{"title":"Default Title","offer_id":50261482963192,"sku":"DN-YS4Y-G9Q8","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/0378\/8792\/files\/51Nyo7z64TL_6bb23748-2e35-42ad-826b-08aff8f4a718.jpg?v=1788114045","url":"https:\/\/westcontrolsupply.com\/products\/d4n-4b20r-b0h3z4dpf8","provider":"West Control Supply","version":"1.0","type":"link"}
