Frequently Asked Questions about 42EF-P2MPB-F4
Question: What are the main benefits of this sensor?
Date Update:16/06/2025
Answer:

The 42EF-P2MPB-F4 offers several clear advantages. Its 3-meter sensing range allows for flexible mounting locations without sacrificing detection capability. The visible red LED simplifies alignment, making installation faster and more accurate. Its compact 18 mm housing allows it to fit in confined spaces where traditional sensors would not be practical. Additionally, the rugged housing and reliable PNP complementary outputs make it highly dependable in harsh and dynamic automation environments.

Question: What output types does it provide?
Date Update:16/06/2025
Answer:
  • PNP (sourcing) logic
  • Complementary Light Operate and Dark Operate signals
  • 4-pin Micro QD output on pigtail cable
  • Works with most DC input modules
  • Reliable switching for object detection and absence sensing

These outputs simplify integration into a wide range of control systems.

Question: How do I mount the 42EF-P2MPB-F4?
Date Update:16/06/2025
Answer:

To mount this sensor:

  • Use the 18 mm cylindrical body to insert into a standard threaded bracket or panel hole.
  • Secure using lock nuts or factory-supplied hardware.
  • Align the sensor face toward the reflector.
  • Ensure nothing blocks the light path.
  • Tighten and check alignment with the LED status before final wiring.

Following these steps ensures accurate positioning and optimal performance.

Question: Can I adjust its sensitivity?
Date Update:16/06/2025
Answer:

No, this model does not include a sensitivity adjustment feature. It is factory-set for optimal performance in most reflective sensing applications. While this limits manual fine-tuning, it eliminates setup errors and simplifies installation for standard use cases.

Question: Is it resistant to harsh conditions?
Date Update:16/06/2025
Answer:

Yes, the sensor is engineered for industrial durability. It withstands wide temperature variations, vibration, dust, and humidity. Its sealed construction and optical filtering also help maintain consistent function in areas with ambient light or dirt exposure. This durability allows it to function in environments where many other compact sensors might fail.
