Panasonic Expands CX‑400 Ver.2 Compact Photoelectric Sensor Portfolio for Demanding Factory‑Automation Environments
Industry Automation News
Panasonic Industry continues to strengthen its amplifier‑built‑in compact photoelectric sensor offering with the widely‑deployed CX‑400 Ver.2 series, covering key part numbers CX‑445A, CX‑444, CX‑442‑P, CX‑442, CX‑424‑Z, CX‑424, CX‑422, CX‑421 and CX‑413, delivering flexible, high‑performance non‑contact object detection for global manufacturing, logistics, packaging and material‑handling applications.
Designed for space‑constrained machine layouts, these square‑form‑factor sensors integrate emitter, receiver and signal processing circuitry within one compact housing, eliminating external amplifier units and simplifying cabinet‑free machine integration. The portfolio includes multiple sensing principles: distance‑set reflective, diffuse reflective, through‑beam and specialised variants, supporting NPN / PNP output options to match diverse PLC and controller interfaces.
Core technical strengths run across the full lineup. All models feature IP67 IEC environmental protection, robust resistance to dust, moisture, cutting fluids and ethanol‑based cleaning agents, supporting deployment in food‑and‑beverage, metal‑processing and wash‑down production zones. Operating temperature spans ‑25 °C to +55 °C, with enhanced immunity against inverter‑generated light noise, ambient illumination and electromagnetic interference to minimise false triggering on busy production floors.
Select distance‑set reflective units such as CX‑445A, CX‑444, CX‑442 and CX‑442‑P adopt advanced optical systems with BGS / FGS switchable modes. Background‑suppression (BGS) reliably ignores rear‑ground disturbances, while foreground‑suppression (FGS) stabilises detection over glossy, reflective or uneven workpiece surfaces. A multi‑turn mechanical adjuster enables precise on‑site sensing‑range calibration, and the built‑in automatic interference‑prevention function permits side‑by‑side multi‑sensor mounting without cross‑talk, maximising layout density on high‑speed conveyor lines.
Diffuse‑reflective models CX‑424‑Z, CX‑424, CX‑422, CX‑421 provide broad‑range presence detection for general‑purpose part‑presence checking, counting and conveyor‑tracking tasks. The CX‑413 through‑beam variant delivers long‑distance beam detection for pallet monitoring, warehouse rack safety and material‑collapse‑detection scenarios. Every sensor incorporates short‑circuit and reverse‑connection protection, fast ≤1 ms response time, plus dual‑colour status LEDs for quick visual diagnosis during commissioning and routine maintenance.
Compared to legacy generations, CX‑400 Ver.2 achieves up to 60 % lower power consumption, cutting operational energy draw and supporting manufacturers’ carbon‑reduction targets without sacrificing detection stability. Products carry CE, UKCA and UL recognitions, fulfilling global machinery‑safety compliance requirements for export‑oriented equipment builders.
“Modern factory automation demands sensors that balance compact footprint, environmental ruggedness and application flexibility,” said a product spokesperson from Panasonic Industry. “This CX‑400 Ver.2 model group gives machine designers a unified hardware platform to solve small‑part detection, background‑conflict suppression and long‑range through‑beam tasks across one product family, reducing part‑number proliferation and simplifying spare‑parts management.”
Target real‑world deployments include packaging machinery, assembly stations, material‑handling conveyors, sorting systems, food‑processing lines and logistics‑automation equipment. Original‑equipment manufacturers and system integrators can select NPN or PNP output, cable length and special‑function variants to satisfy specific machine specifications.
Engineers can access full datasheets, CAD files and application notes for the complete CX‑400 series lineup including CX‑445A, CX‑444, CX‑442‑P, CX‑442, CX‑424‑Z, CX‑424, CX‑422, CX‑421 and CX‑413 via official Panasonic Industry technical resources.
