Leuze FT328.3/2N (Order Code: 50122720)

Product Overview: The Leuze FT328.3/2N energetic diffuse photoelectric sensor is a high-performance short-range object diagnostics instrument belonging to the world-renowned cylindrical Series 328 portfolio, engineered and manufactured by Leuze in Germany. Within modern automated machinery frameworks, automated packaging units, conveyor sorting structures, and material handling systems, executing non-contact target tracking with optimized space utilization is a core layout requirement.

The FT328.3/2N variation profiles both the light transmitter and receiver nodes on a single front optical plane, operating completely independently without requiring an external reflector sheet or separate receiver blocks. The defining physical asset of this specific model centers on its premium stainless steel V2A housing paired with solid-state integration, preserving absolute tracking fidelity and ensuring continuous 24/7 industrial automation runtimes without drift errors.

Energetic Diffuse Processing Paradigm and Target Material Contrast: The underlying technological paradigm driving the FT328.3/2N variant leverages sophisticated Energetic Diffuse Reflection physics. The sensor's active front lens PROJECTS a high-intensity visible Red LED beam with a 620 nm wavelength outward into the proximate spatial tracking zone. When a target object passes through this beam path, its physical surface area diffusely reflects the red light back into the optical lens array of the device. Once the accumulated soundwave light energy threshold matches the internal calibrated logic parameter, the solid-state NPN transistor loop instantly shifts state to pass automated control discrete data over long cable runs straight to a central controller.

Because this mechanism tracks raw returned energy values, the effective switching threshold is heavily bound to the relative contrast, color, and finish of the passing phôi medium:

• Standard White Surfaces (90 percent reflectivity): Assured operating range covers from 1 mm to 215 mm, with an absolute typical maximum limit of 280 mm.

• Neutral Gray Surfaces (50 percent reflectivity): Assured operating range covers from 1 mm to 190 mm, with an absolute typical maximum limit of 245 mm.

• Standard Matte Gray Surfaces (18 percent reflectivity): Assured operating range covers from 3 mm to 150 mm, with an absolute typical maximum limit of 190 mm.

• Deep Carbon Black Surfaces (6 percent reflectivity): Assured operating range covers from 5 mm to 125 mm, with an absolute typical maximum limit of 160 mm.

🛠️ CRITICAL FIELD CONTROL & HARDWARE ADVANTAGES:

• Integrated Intelligent Teach Button Interface: Moving away from legacy optical instrumentation utilizing manual mechanical potentiometer dials prone to wiper degradation, slot stripping, or vibration-induced drift, the FT328.3/2N features a solid-state Teach Button. Installation crews simply place the phôi medium at the targeted boundary distance and engage the button to instruct the integrated digital microprocessor to lock onto the current light profile with tight resolution, stabilizing plant changeovers during model shifts.

• Synchronized Telemetry NPN Output Matrix: Features concurrent real-time data loops via two independent solid-state channels: Output 1 (NPN - Light Switching / Energizes on object capture) and Output 2 (NPN - Dark Switching / Energizes on beam break). This dual architecture empowers supervisory controllers to interface with the preferred logic state straight from the hardware without requiring secondary logic-inverting hardware inside the electrical panel.

Severe-Duty Environmental Hardening Specifications: Forged with a standard cylindrical M18 x 1 mechanical threading outline and a compact total casing length of 46 mm, the outer shell is machined from high-grade industrial Stainless Steel V2A (AISI 304 grade) coupled with a tough ABS back-cap assembly. This structural package provides a total hardware net weight of 40 g, effortlessly deflecting physical impact shocks.

Certified to international IP67 protective ingress ratings, it provides a dust-tight barrier immune to fluid splashes, operating with absolute consistency over an extended thermal window scaling from minus 40 up to plus 60 degrees Celsius, making it an exceptional part choice for industrial food flash-freezing grids or outdoor lines.

Electrical interface routing utilizes a pre-wired high-flex 2-meter PUR jacketed cable, which offers superb defense against industrial grease and oil matrices. The 4-conductor wiring loom uses standard industrial color codes (Brown lead: positive supply, Blue lead: negative common, Black lead: Output 1, White lead: Output 2). Resolving process velocity changes with a switching pulse frequency of precisely 500 Hz (1 ms response latency), the sensor tracks high-density product currents without data dropouts.
