LEUZE LS46C.8-M12 THROUGH-BEAM PHOTOELECTRIC SENSOR (PART NUMBER: 50127045)

PRODUCT OVERVIEW
The Leuze LS46C.8-M12 (Part Number: 50127045) is a premium-tier photoelectric sensor belonging to the renowned 46C Series developed by Leuze electronic. This device functions exclusively as the Transmitter (TX) component within a Through-beam Photoelectric Sensor configuration, engineered specifically for long-range object detection and highly demanding industrial environments.

SPECIALIZED OPERATING PRINCIPLE
As a fundamental part of a through-beam system, the LS46C.8-M12 does not operate as a standalone unit. It must be paired with a compatible 46C Series Receiver (RX):
- The LS46C.8-M12 transmitter continuously emits a stable, highly visible red LED beam at a wavelength of 630 nm directed toward the receiver.
- Under normal, unobstructed conditions, the receiver continuously captures this light signal.
- The moment an object interrupts the light path between the transmitter and receiver, the light transmission cycle is instantly broken. The receiver immediately toggles its electrical output state (ON/OFF), transmitting a digital control signal to the central PLC or automated control system.

EXTRAORDINARY SENSING RANGE
The core competitive advantage of this model over standard reflective or diffuse sensors (which typically top out at 2–20 m) lies in its extreme distance performance:
- Guaranteed Operating Range: 0.5 meters to 120 meters.
- Maximum Typical Operating Limit: Up to 150 meters.
This extensive dải đo makes the sensor ideally suited for large-scale industrial warehouses, long linear conveyor monitoring, and vehicle detection at checkpoint gates.

INTEGRATED ACTIVATION INPUT FUNCTION
Unlike baseline sensors, the LS46C.8-M12 features a dedicated Activation Input pin. This advanced function allows the master controller (PLC) to actively turn the transmitter's LED beam on or off based on specific production cycles. This mechanism significantly reduces power consumption, extends the life of the red LED diode, and prevents cross-talk interference when multiple sensors are installed in close proximity.

ROBUST MECHANICAL DESIGN & ENHANCED ENVIRONMENTAL PROTECTION
- Heavy-Duty Enclosure: The sensor body is molded from high-grade PC-PBT engineering plastics, ensuring excellent impact resistance, chemical compatibility, and immunity against factory floor high-frequency vibrations. The protective lens window is constructed from optical-grade PMMA for superior beam transmission.
- Dual IP67 and IP69K Rating: Guarantees complete dust ingress protection and absolute watertightness. The housing is fully certified to withstand rigorous high-pressure, high-temperature washdown procedures common in clean-in-place processing facilities.
- Extended Temperature Range: Capable of continuous operation from -40°C up to +60°C, making the LS46C.8-M12 the ideal component for industrial deep-freezers, cold storage facilities, and exposed outdoor infrastructure.
