Machine safety – light curtains are an important component of modern industrial technology, and the MS4800B-20-0440 has become increasingly popular in this field. This article outlines the application, field, and working principle of the MS4800B-20-0440.

What is the MS4800B-20-0440 The MS4800B-20-0440 is a safety light curtain designed and manufactured by Schneider Electric. It is designed to provide an extra layer of safety in applications where personnel and machines must work together in close proximity. Specifically, the MS4800B-20-0440 is designed to detect people or objects that pass between the safety light curtain’s frequency, thus triggering the appropriate safety measures, such as shut down of the machine.

ApplicationsThe MS4800B-20-0440 is a versatile safety device with applications in the manufacturing, material handling, and food and beverage industries. It can also be used in mining, and robotics operations. In general terms, this safety light curtain is employed in any environment where machine operators and robots must work together in close proximity.

Fields of UseThe MS4800B-20-0440 light curtain is used in a variety of situations, including:

• Machine safeguarding
• Robot warning systems
• Safety gate systems
• Welding safety systems
• Loading docks
• Signal towers

The safety light curtain is also used in hazardous work environments to protect personnel from accidents due to machinery hazards, such as runaway robots or other physical hazards. The device is designed to be easy to install and use, and it is often used as part of a multi-layered safety system.

Working PrincipleThe working principle of the MS4800B-20-0440 is based on the use of infra-red (IR) light beams. The light curtain is composed of two sets of opposite-facing IR LEDs and photo-diodes located in the two halves. The IR LED emits an invisible light beam that is received by the photo-diode on the other side. If the beam is blocked or interrupted by a person or object, the safety mechanism is activated.

The device also works in tandem with other safety devices. For example, the safety light curtain is designed to detect and respond to an emergency stop signal from an emergency switch, such as a foot pedal. This signal is then transmitted to the safety controller, which initiates the appropriate safety measures.

In addition, the MS4800B-20-0440 can also be used with limit switches. These switches are wired in series with the safety light curtain to increase the sensitivity of the safety system, and they also ensure that even when the safety light curtain is blocked, the limit switch will still signal the safety controller and immediate safety measures will be initiated.

The MS4800B-20-0440 also features an external operating voltage, thereby reducing the risk of electric shock or injury in hazardous environments.

Conclusion The MS4800B-20-0440 is a versatile and reliable safety device that is widely used in a range of industries to protect personnel from machine hazards. It is designed to be easy to install and use, and it can also be integrated with other safety devices such as emergency switches, limit switches, and safety controllers. The IR light beam principle of operation provides an extra layer of protection when personnel and machinery must work in close proximity.
