LEUZE ET318B.3/2N ENERGETIC DIFFUSE PHOTOELECTRIC SENSOR (PART NUMBER: 50122565)

PRODUCT OVERVIEW
The Leuze ET318B.3/2N (Part Number: 50122565) is a high-grade energetic diffuse reflection photoelectric sensor belonging to the reliable 318B Series developed by Leuze electronic. Featuring an integrated optical configuration where both the transmitter and receiver elements are encapsulated into a standard M18 cylindrical threaded body, this sensor operates completely standalone without the need for additional mirrors, reflectors, or separate receiver blocks. It offers an optimal and highly cost-effective automation solution for object profiling and product tracking on conveyor systems due to its minimalist mounting requirements.

BREAKTHROUGH INTEGRATED OPTICAL TECHNOLOGIES
The ET318B.3/2N is packed with Leuze's proprietary optical engineering suites, offering excellent deployment advantages on the factory floor:
- A²LS Technology (Active Ambient Light Suppression): An advanced algorithmic suite that identifies, isolates, and completely suppresses foreign optical interference coming from factory lighting, overhead fluorescents, or stray sunlight reflections. This ensures zero false triggering and guarantees steady data streams.
- brightVision Light Spot: Emits a highly visible, razor-sharp red LED beam spot that allows maintenance technicians to visually calibrate focal target alignment instantly on-site without complex tuning meters.

INTELLIGENT CALIBRATION VIA THE EMBEDDED TEACH-IN BUTTON
Departing from obsolete mechanical potentiometers that degrade due to severe vibrations and mechanical wear, the ET318B.3/2N features a smart electronic Teach-In button directly built onto the rear shell. The setup process is remarkably simple: place the target sample in front of the optical beam, press and hold the Teach button, and the sensor will automatically analyze the contrast level, locking the most reliable detection threshold between the object and the background structure. This drastically cuts downtime during frequent production product changeovers.

HIGH-SPEED RESPONSE PERFORMANCE & DUAL TRANSISTOR OUTPUT ARRAY
- Impressive 500 Hz Switching Frequency paired with an ultra-short 1 ms response time: Enables the device to precisely capture high-velocity item movements on express conveyor systems, run continuous unit counts, and verify component presence inside rapid automatic packaging machinery and high-speed label applicators without trailing edge errors.
- Pre-Configured Dual NPN Transistor Outputs: Saves significant software configuration time by providing Output 1 pre-set to Light Switching mode (Light ON - output state closes when object reflection is registered) and Output 2 pre-set to Dark Switching mode (Dark ON - output state closes when light path remains unobstructed).

STANDARD M18 HARDWARE FOOTPRINT & INDUSTRIAL DURABILITY
- Standard M18 Form Factor: Molded from high-grade, ultra-lightweight ABS engineering plastic with a total housing length of 46 mm, it serves as a direct drop-in replacement for existing standard M18 sensors on pre-installed factory mounting brackets.
- IP67 Ingress Protection: Ensures the internal electronics are completely dust-tight and resistant to water splashes. Combined with a wide operational temperature range spanning from severe freezing zones at -40°C up to high-ambient settings of +60°C, it delivers long-term reliable service from automated logistics warehouses and cold chain distribution centers to heavy industrial production plants.
