LEUZE RK3CL1.A3/6T-M8 LASER RETRO-REFLECTIVE PHOTOELECTRIC SENSOR (PART NUMBER: 50143653)

PRODUCT OVERVIEW
The Leuze RK3CL1.A3/6T-M8 (Part Number: 50143653) is a high-tech unpolarized retro-reflective photoelectric sensor from the compact 3C Series line manufactured by Leuze electronic. This device utilizes a Class 1 visible red laser beam with extreme focal concentration, paired with digital signal evaluation to deliver absolute measurement accuracy. It stands as an ideal sensing component for advanced automation systems where lightning-fast response times and extremely tight mounting conditions are mandatory.

BREAKTHROUGH COAXIAL AUTOCOLLIMATION TECHNOLOGY
The core engineering feat that sets the RK3CL1.A3/6T-M8 apart from standard retro-reflective options is its integrated coaxial Autocollimation optics:
- This technology forces the emitted laser beam and the incoming reflected light to travel along the exact same optical axis.
- Practical Benefit: It completely eliminates the physical blind spot at close range, allowing the sensor to detect ultra-small objects or microscopic micro-components with absolute certainty. Furthermore, it vastly simplifies alignment procedures during setup and ensures robust operational immunity when tracking high-gloss materials.

SPECIALIZED DETECTING PERFORMANCE FOR HIGH-GLOSS SURFACES
This model is intentionally engineered by Leuze for the critical "Detection of high-gloss or polished surfaces." It completely resolves the persistent tracking errors common to traditional photoelectric sensors, which often misinterpret brilliant surfaces as the optical reflector itself:
- Seamlessly registers polished metals, stainless steel phôi, bright chrome-plated assemblies, mirrored panels, and high-shine precision hardware components without any signal jitter.

ULTRA HIGH-SPEED CAPACITY & FLEXIBLE PUSH-PULL OUTPUT
- Blazing-Fast 3000 Hz Switching Frequency: The sensor executes up to 3000 switching cycles per second, coupled with an ultra-short response time of only 0.17 ms. This dynamic rating makes it perfect for micro-component tracking on fast manufacturing lines, high-volume PCB sorting in electronic assembly, and ultra-high-speed packaging machines.
- Flexible Push-Pull Transistor Output: Supports both Light Switching (PNP) and Dark Switching (NPN) states within a single smart interface. This allows direct hardware integration into mainstream PLC systems—including Siemens, Mitsubishi, Omron, Schneider, and Allen Bradley—without needing additional signal conversion modules.

ULTRA-COMPACT FOOTPRINT & SEVERE TEMPERATURE RESISTANCE
- Minimalist Geometry: Measuring an ultra-miniaturized 11.4 × 34.2 × 18.3 mm and weighing a mere 10 g, the sensor effortlessly integrates into deep recess spaces and tightly packed machine chassis. Its durable PC-ABS housing and premium PMMA optical window guard against heavy factory floor vibration.
- Combined IP67 and IP69K Rating: Ensures absolute hermetic insulation against fine dust and intense industrial high-pressure hot water washdowns. With a freezing tolerance down to -40°C, it operates flawlessly in deep-freeze cold storage logistics and modern food processing lines.
