LEUZE PRK46C.D1/PX-M12 POLARIZED RETRO-REFLECTIVE PHOTOELECTRIC SENSOR (PART NUMBER: 50127028)

PRODUCT OVERVIEW
The Leuze PRK46C.D1/PX-M12 (Part Number: 50127028) is a premium polarized retro-reflective photoelectric sensor from the high-performance 46C Series manufactured by Leuze electronic. This device is highly specialized and optimized for the demanding task of detecting highly reflective and transparent objects, such as stretch-wrapped pallets, shrink film, blister packs, and clear plastic wrap, which easily deceive conventional optical sensors.

WORKING PRINCIPLE WITH ADVANCED POLARIZATION FILTER
The sensor operates on a retro-reflective principle, encapsulating both the transmitter and receiver elements within a single high-grade housing:
- It emits a high-visibility pulsed red LED beam towards a dedicated reflector positioned opposite and continuously monitors the returned beam. When an object breaks this optical path, the electrical output state instantly triggers.
- The most crucial element of the PRK46C.D1/PX-M12 is its integrated polarization filter. This filter ensures that only the specifically polarized light bouncing back from the optical reflector is registered by the internal receiver. Consequently, the sensor completely ignores false reflections coming from glossy shrink-wraps, shiny metallic surfaces, or clear foils, delivering absolute data reliability.

LONG SENSING RANGE & OPTIMIZED OPTICS
- Superior Operating Distance: When paired with a standard TK(S) 100x100 reflector, the sensor achieves a guaranteed operating distance spanning from 0.1 meters up to 16 meters, with a maximum typical limit of 20 meters. This makes it ideal for wide automated production cells and assembly lines.
- 630 nm Pulsed Red LED Light Source: The visible red beam enables quick, hassle-free alignment during physical installation. The pulsed light technology guarantees excellent immunity against heavy ambient lighting or stray industrial shop floor illumination.

ROBUST MECHANICAL BUILD & SEVERE ENVIRONMENT RESISTANCE
- Heavy-Duty PC-PBT Housing: Combining Polycarbonate and Polybutylene Terephthalate, the rugged housing is designed to withstand harsh mechanical impacts, factory vibrations, and heavy washdown chemical agents. The lens is crafted from PMMA to ensure long-term scratch resistance and optimal transparency.
- Dual IP67 and IP69K Washdown Certified: Provides total dust ingress protection and absolute hermetic sealing against high-pressure, high-temperature hot water jets. Capable of continuous operation in freezing deep-cold environments down to -40°C up to high heat conditions of +60°C, making it perfect for cold storage chains, food processing, and exposed outdoor environments.
