Introduction

MS4800B-20-0800-Q2-10X-10R is a machine safety light curtain, which is used to detect and prevent accidents in production facilities. It features special detection capabilities such as dielectric strength, immunity from extraneous light, additional shielding capability and additional insulation capability.

Application Field

MS4800B-20-0800-Q2-10X-10R is suitable for detecting multiple hazards, such as robotic collision detection, pinching or crushing, and personnel accesses. The environment conditions where it can be used include temperatures from -10°C to +50°C, relative humidity in the range of 10%-90% non-condensing and IP40 casing protection. It is suitable for use in factories or workshops and other places where there is potential danger. Robot collision detection systems can be installed in the areas that robots are in use, requiring an operator to be present at all times. The MS4800B-20-0800-Q2-10X-10R will detect any unsafe proximity between the robotic arm and any personnel or objects. It can be set up to provide active scanning with a range of 20 cm and a 3cm reaction time, and a safety zone of 6 cm.In addition, it can be used to protect against pinch points in doorways or between machinery components. This can be accomplished by installing multiple light curtain beams side by side, creating a detected zone that essentially acts like a wall and emits an error signal when breached.

Working Principle

The MS4800B-20-0800-Q2-10X-10R operates on the principle of photocouplers and light curtains. The main components include an optically shielded Emitter and Receiver. The Emitter emits infrared light through 4 LEDs, while the Receiver detects the presence of the infrared light. When an object enters the detected zone, the light is either blocked or reflected away, thus triggering an error signal.The operating principle is one of point interruption. This means that when a person or object enters the detection zone, then the light beams from the Emitter to the Receiver will be interrupted, making the Receiver detect the interruption resulting in an error signal.This signal can then be sent to a Machine Controller or any other safety device through a PLC system. The PLC will then interpret the signal and take the appropriate action, which can range from slowing down or stopping a robot’s motion, to activating a warning light or even interlocking a machine or guard.

Conclusion

The MS4800B-20-0800-Q2-10X-10R is a machine safety light curtain used to detect and prevent accidents in production facilities. It is suitable for detecting multiple hazards, such as robot collision detection, pinching or crushing, and personnel accesses. It operates on the principle of photocouplers and light curtains, where an optically shielded Emitter and Receiver are used to send and detect an infrared light passing through the detection zone, triggering an error signal when the light is blocked or reflected away. This light curtain can be installed and used in multiple environments and its signals can be linked to a PLC’s system, being interpreted and used to take the appropriate safety action.
