This model is designed to provide protection at critical points—such as machine openings and hazardous zones—by reliably detecting finger-level intrusions with a fine 14 mm beam resolution. The 440L-P4J0320YD features a protected height of 320 mm and utilizes 32 beams to create an invisible barrier, quickly halting dangerous machine motion when any beam is interrupted. With its compact aluminum housing and IP65 protection rating, the GuardShield is built for robust operation in demanding environments. Easy-to-integrate connectors and multiple configuration options ensure that this solution supports a wide range of safeguarding strategies on modern machinery, supporting compliance with international safety standards.\n\n\u003ch2\u003eKey Features of Allen Bradley 440L-P4J0320YD\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eType 4 finger protection safety light curtain for critical safety zones\u003c\/li\u003e\n  \u003cli\u003e14 mm beam resolution allows detection of small objects such as fingers\u003c\/li\u003e\n  \u003cli\u003eProtected height of 320 mm with 32 beam pairs for full coverage\u003c\/li\u003e\n  \u003cli\u003eFast response time (≤20 ms) for immediate machine stoppage\u003c\/li\u003e\n  \u003cli\u003eScanning range from 0.3 m to 7 m supports flexible deployment\u003c\/li\u003e\n  \u003cli\u003eEDM, fixed and floating blanking, beam coding, start\/restart interlock\u003c\/li\u003e\n  \u003cli\u003eDurable aluminum housing, IP65 rated for dust and water resistance\u003c\/li\u003e\n  \u003cli\u003eCertified to PL e (ISO 13849-1), SIL 3 (IEC 61508), TUV and CE marked\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 440L-P4J0320YD\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSafety Type: Type 4 (IEC\/EN 61496)\u003c\/li\u003e\n  \u003cli\u003eProtected Height: 320 mm\u003c\/li\u003e\n  \u003cli\u003eBeam Resolution: 14 mm\u003c\/li\u003e\n  \u003cli\u003eNumber of Beams: 32\u003c\/li\u003e\n  \u003cli\u003eResponse Time: ≤20 ms\u003c\/li\u003e\n  \u003cli\u003eSupply Voltage: 24 VDC (19.2–28.8 VDC)\u003c\/li\u003e\n  \u003cli\u003eOutput Current: 0.4 A max\u003c\/li\u003e\n  \u003cli\u003eScanning Range: 0.3–7 m\u003c\/li\u003e\n  \u003cli\u003eIP Rating: IP65\u003c\/li\u003e\n  \u003cli\u003eDimensions: 42 mm (W) × 52 mm (D) × 472 mm (H)\u003c\/li\u003e\n  \u003cli\u003eConnectors: 4-pin (Sender), 8-pin (Receiver) M12\u003c\/li\u003e\n  \u003cli\u003eCompliance: ISO 13849-1 PLe, IEC 61508 SIL3, TUV, CE\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\nAllen Bradley 440L-P4J0320YD is ideal for safeguarding machinery where reliable presence detection is required to protect operators from hazardous motion. Common use cases include robotic cells, automated presses, material forming stations, conveyor systems, and electronic assembly workstations. Thanks to its fine 14 mm resolution, this model excels in finger and hand detection applications—making it suitable for point-of-operation safety where close interaction with moving equipment is frequent. Its flexible configuration options allow for deployment in both perimeter and access guarding scenarios, enabling high safety performance without impeding workflow. With quick-disconnect cabling and DIP-switch selectable features like blanking and EDM, integration and maintenance are streamlined for OEMs and plant engineers.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/examples-of-industrial-automation-control-systems\" target=\"_blank\"\u003eExamples of Industrial Automation and Control Systems\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-194e-sy\" target=\"_blank\"\u003eAllen Bradley 194E-SY Disconnect Switch – Safety and Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1783-ims28rac\" target=\"_blank\"\u003eAllen Bradley 1783-IMS28RAC Managed Switch for Industrial Safety Networks\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- SEO \u0026 metadata below --\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870771757355,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_7456beca-4018-4364-92f8-982c0b0ed658.png?v=1723532460","url":"https:\/\/leadtime.ca\/products\/allen-bradley-440l-p4j0320yd","provider":"LEADTIME","version":"1.0","type":"link"}
