ML4.2-R/40b/95/110 Pepperl+Fuchs Photoelectric Sensors

Pepperl+Fuchs ML4.2-R/40b/95/110 Overview

The Pepperl+Fuchs ML4.2-R/40b/95/110 series are miniature photoelectric sensors belonging to the ML4.2 family. These sensors are typically used as diffuse sensors with background suppression. The specific numbers and letters in the model name indicate particular configurations and features.

Product Detailed Description

• Function:

• Detects the presence or absence of objects.

• Diffuse principle: the sensor emits light, and the output signal changes when the light is reflected back by an object and received by the sensor.

• Background suppression function: reliably detects target objects while ignoring background objects, especially suitable for applications with low color contrast or significant background interference.

• Features:

• Miniature design, saving installation space.

• Reliable background suppression performance.

• Visible red light emitter for easy alignment.

• High switching frequency, suitable for high-speed applications.

• Rugged industrial housing.
