This flat-pack, rectangular sensor includes two normally closed (N.C.) safety outputs and one normally open (N.O.) auxiliary output, all solid-state and rated for 200 mA at 24 VDC. Its 5-pin M12 quick-disconnect pigtail connector (6 in cable) simplifies installation and replacement, especially in modular or hygienic applications. With an IP69K and NEMA 3\/4X\/12\/13 rating, the plastic housing is ideal for washdown environments such as food and beverage, pharmaceuticals, or packaging. It complies with C-TICK, CCC, and KC certifications, making it suitable for use in international safety systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eActuator Type: Rectangular RFID-based non-contact standard actuator.\u003c\/li\u003e\n\u003cli\u003eContact Configuration: 2 N.C. safety outputs + 1 N.O. auxiliary output, solid-state.\u003c\/li\u003e\n\u003cli\u003eCurrent \u0026amp; Voltage Rating: 200 mA max at 24 VDC, standard for safety logic circuits.\u003c\/li\u003e\n\u003cli\u003eConnection Type: 6 in pigtail with 5-pin M12 DC micro quick-disconnect connector.\u003c\/li\u003e\n\u003cli\u003eMaterial \u0026amp; Enclosure: Durable plastic with IP69K, NEMA 3\/4X\/12\/13 protection ratings.\u003c\/li\u003e\n\u003cli\u003eTemperature Rating: Operates reliably from -10°C to +55°C.\u003c\/li\u003e\n\u003cli\u003eCertifications: C-TICK, CCC, KC — meeting international safety requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 440N-Z21SS2J provides advanced, hygienic, and maintenance-friendly safety monitoring for guard doors, gates, and access panels in demanding industrial environments.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":49105388175616,"sku":"440N-Z21SS2J","price":304.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/shopping_53_81854473-4d41-4e2f-a0a0-76a4d2764bf8.webp?v=1785546070","url":"https:\/\/alotechparts.com\/products\/440n-z21ss2j-allen-bradley-guardmaster-440n-non-contact-switch","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
