Leuze FT318BI.3/2N-M12 (Order Code: 50127997)

Product Overview: The Leuze FT318BI.3/2N-M12 energetic diffuse photoelectric sensor is a high-performance short-range object diagnostics instrument belonging to the world-renowned cylindrical Series 318B portfolio, engineered and manufactured by Leuze in Germany. Within modern automated machinery frameworks, automated packaging blocks, high-speed sorting conveyor junctions of smart logistics centers, and rapid multi-axis production assembly systems, executing reliable target telemetry with minimized space requirement and flexible deployment routing is a core control setup.

The FT318BI.3/2N-M12 variation integrates both the pulsed infrared light emitting node and the receiver circuit block onto a single front optical plane, operating completely independently without requiring an external retro-reflective reflector sheet or separate remote receiver blocks, driving down material overheads and simplifying field mechanical plumbing layout.

The Engineering Assets of Infrared Electro-Optics: The hallmark hardware differentiator of the FT318BI.3/2N-M12 configuration focuses on its premium Infrared LED light source emitting a 850 nm wavelength pulsed signal, moving away from visible red beams. Utilizing an invisible sonic-optical light wave vector unlocks two critical operational advantages for facility control loops:

• Target Color and Contrast Immunity: The extended wavelength characteristics of infrared light secure a more uniform optical absorption profile across diverse materials. This mechanism dramatically scales down distance migration errors or range contraction common when target items abruptly shift from light-toned paper shells to high-contrast dark surfaces (such as carbon black compounds or dark glossy polymer films).

• Absolute Protection Against Ambient Lighting Interference: Locked onto the 850 nm infrared band and driven by a pulsed frequency tracking filter, the internal calculation core entirely rejects external light pollution from high-power facility halogen arrays, industrial overhead lighting setups, or direct solar glare, eliminating false output triggers on the plant floor.

Sensing Range Profiles Across Target Material Finish Contrast: Because energetic diffuse technology relies entirely on tracking raw returned light volumes, the effective operational switching distance is heavily bound to the relative contrast and reflectivity of the passing target medium. Laboratory compliance auditing verifies the following assured dynamic bounds:

• Standard White Surfaces (90 percent reflectivity target matrix): Assured operating range covers seamlessly from 1 mm to 215 mm. The absolute maximum limit under clean facility conditions can reach up to 280 mm.

• Neutral Gray Surfaces (50 percent reflectivity target matrix): Assured operating range covers stably from 1 mm to 190 mm.

• Standard Matte Gray Surfaces (18 percent reflectivity target matrix): Assured operating range covers from 3 mm to 150 mm.

• Deep Carbon Black Surfaces (6 percent reflectivity target matrix): Assured operating range covers smoothly from 5 mm to 125 mm.

🛠️ CRITICAL INTEGRATION ARRAY & ELECTRICAL BACKBONE:

• Synchronized Telemetry NPN Output Matrix: Features concurrent real-time data loops via two independent solid-state channels: Output 1 (NPN - Light Switching / Energizes current loop on reflection capture) and Output 2 (NPN - Dark Switching / Energizes current loop 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, boosting cycle runtime speeds.

• Connectorized M12 Quick-Disconnect Interface: Moving away from pre-wired cable configurations, this variation features an integrated M12 Male Connector with a 4-pin, A-coded layout. This layout empowers field technicians to swap or update sensor heads without re-routing or pulling lengthy cable lines through extensive conduit runs, minimizing automated facility downtime during maintenance windows.

Severe-Duty Environmental Hardening Specifications: The sensor body frame is cast entirely from high-grade industrial ABS polymer resin, providing premium mechanical strength against extreme vibration shocks generated by high-power packaging grids or automated sorting motors. It is machined with a standard cylindrical M18 x 1 mechanical threading outline and a compact total casing length of 46 mm, weighing an ultra-lightweight 20 grams—perfect for protecting structural dynamics on high-velocity robotic tool arms.

Certified to international IP67 protective ingress ratings and Class III electrical safety standards, the internal circuitry is reinforced with native reverse polarity power isolation and output short-circuit barrier containment. The device runs smoothly on a flexible industrial utility range of 10 to 30 VDC, consuming an exceptionally efficient no-load current of less than or equal to 20 mA, and handles extreme thermal facility boundaries spanning from minus 40 up to plus 60 degrees Celsius (ideal for industrial food flash-freezing grids).

The backplate integrates a solid-state Teach Button for fast boundary locking alongside high-visibility indicator LEDs tracking power stability and signal switching activity. 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.
