Description

The Panasonic SUNX PM-L44 photoelectric sensor utilizes a U-slot through-beam configuration, where the infrared emitter and receiver are housed opposite each other within a single plastic body. This design provides precise detection of objects passing through the 5mm slot, with the output toggling based on the interruption of the infrared beam. The sensor operates on a wide 5-24VDC range, making it compatible with various PLCs, microcontrollers, and industrial control systems.

Featuring an NPN open-collector transistor output, it can sink up to 50mA, suitable for directly driving small relays or interfacing with digital inputs. The infrared LED emitter operates at a 940nm wavelength, offering a good balance of visibility and immunity to ambient light interference. Its compact, black plastic housing is designed for chassis mounting in space-constrained applications.

Key Features

  • Compact U-slot through-beam photoelectric sensor with integrated emitter and receiver.
  • Fixed 5mm sensing gap for precise object detection and counting.
  • Broad 5-24VDC operating voltage ensures compatibility with industrial and embedded systems.
  • NPN open-collector output provides Light-ON (object present) or Dark-OFF logic.
  • Infrared LED emitter with 940nm peak wavelength for stable, interference-resistant operation.
  • Low residual voltage (0.7V max at 50mA) ensures strong signal integrity.
  • Robust plastic housing designed for chassis mounting in automated equipment.
  • Low current consumption (≤15mA) for energy-efficient continuous operation.

Applications

  • Object detection and counting on conveyor belts and packaging lines.
  • Paper or sheet presence verification in printers and copiers.
  • Position verification and limit sensing in small automated machinery.
  • Coin or token detection in vending machines and payment systems.
  • Small-part detection and sorting in assembly and manufacturing equipment.

Frequently Asked Questions

What is the operating voltage range for the Panasonic SUNX PM-L44 sensor?

The Panasonic SUNX PM-L44 operates on a wide DC voltage range from 5V to 24V. This makes it compatible with common industrial control voltages like 12V or 24V, as well as lower-voltage microcontroller systems running on 5V.

How does the Light-ON / Dark-OFF output logic work?

The sensor uses Light-ON / Dark-OFF logic. When an object is NOT present in the U-slot (the infrared beam is received), the NPN output transistor is ON, sinking current to ground. When an object blocks the beam, the output turns OFF. This is a standard configuration for many PLC inputs.

What is the maximum load the NPN output can drive?

The NPN open-collector output can sink a maximum continuous current of 50mA with a residual voltage of 0.7V or less. This is sufficient to directly drive small relays, indicator LEDs, or serve as a digital input signal for PLCs, Arduino, or other controllers.

How do I wire the two leads of the sensor?

The sensor has two wires. Connect the brown wire to the positive supply voltage (5-24VDC) and the blue wire to the load (e.g., a PLC input or relay coil). The other side of the load connects to the positive supply. The sensor's internal NPN transistor switches the blue wire connection to ground when active.
