ML4.2-T-8m-RT/76a-95 Pepperl+Fuchs Photoelectric Sensors

Pepperl+Fuchs ML4.2-T-8m-RT/76a-95 Overview

The Pepperl+Fuchs ML4.2-T-8m-RT/76a-95 series are miniature through-beam photoelectric sensors belonging to the ML4.2 family. The "T" in the model typically indicates the Transmitter, which is used in conjunction with a Receiver to detect objects that interrupt the light beam.

Product Detailed Description

• Function:

• Detects the presence or absence of objects by monitoring the status of the light beam between the transmitter and receiver.

• When an object blocks the light beam emitted by the transmitter, the receiver does not detect the light, thus changing its output signal.

• Less affected by the color and surface properties of the object, suitable for detecting various types of objects.

• Features:

• Miniature design, saving installation space.

• Reliable detection performance, unaffected by ambient light interference.

• Visible red light emitter for easy alignment and adjustment.

• Long sensing range, suitable for wider working areas.

• Rugged industrial housing.

Product Parameters

As the model number is very specific, and parameters may vary between sub-models, the following are typical parameters for the ML4.2 series through-beam sensors. Always refer to the official datasheet for the specific ML4.2-T-8m-RT/76a-95 model:

• Sensor Type:

• Through-beam transmitter (requires a separate receiver).

• Emitter Type:

• Visible red light LED.

• Maximum Sensing Range:

• Typically related to the paired receiver model. "8m" likely indicates a typical maximum sensing range of 8 meters that this transmitter can support.

• Operating Voltage:

• Typically 10 V DC to 30 V DC.

• Power Consumption:

• Usually low.

• Connection Type:

• Cable connection or M8/M12 connector.

• Protection Degree:

• Typically IP67.

• Ambient Temperature:

• Operating temperature range typically from -25 °C to +55 °C.

Product Advantages

• High Reliability:

• The through-beam principle is less affected by ambient light, object color, and surface properties, resulting in high detection reliability.

• Long Sensing Range:

• Suitable for wider working areas.

• Easy Alignment:

• Visible red light facilitates alignment between the transmitter and receiver.

• Miniature Design:

• Suitable for space-constrained applications.

• Rugged and Durable:

• Suitable for industrial environments.

Precautions

• Correct Installation:

• Install and secure the transmitter according to the instructions in the product manual, and align it with the corresponding receiver, ensuring the light beam is unobstructed.

• Environmental Conditions:

• Avoid using the sensor in environments exceeding its operating temperature and humidity ranges.

• Avoid strong vibrations and shocks.

• Power Connection:

• Ensure the power supply voltage is within the allowable range and connect the power wires correctly.

• Paired Usage:

• This transmitter must be used in conjunction with a compatible Pepperl+Fuchs through-beam receiver to form a complete detection system. Refer to the official manual to identify compatible receiver models.

• Regular Cleaning:

• Regularly clean the optical surface of the transmitter to ensure the intensity of the emitted light beam.

Product Applications

• Automation Technology:

• Object detection, counting, positioning.

• Conveyor Technology:

• Detecting whether objects pass through on conveyor belts.

• Packaging Machinery:

• Detecting whether packaging materials or products are in place.

• Access Control:

• Detecting the passage of people or vehicles.

• Safety Protection:

• Used in safety light curtains or light barriers and other safety protection systems.
