Machine Safety - Light Curtains

Light curtains, also known as light barriers, are safety devices used to restrict access to danger areas to personnel with proper clearance. The XC40S-0901A0A00AB0, produced by Pilz GmbH & Co. KG, is a light curtain measuring 229 mm high with a resolution of 18 x 18 mm. It is designed to protect against defined hazardous points and ensure a safe working environment.

Application Field

The XC40S-0901A0A00AB0 is an advanced light curtain that can be used in a variety of industries and applications. It is suitable for use in machinery and plants that require a high degree of safety. It is also suitable for applications where it is necessary to monitor people or objects, for example, monitoring workers in hazardous areas or controlling access to sensitive areas. It is also widely used in automatic machinery, such as elevators and industrial robots, for protection against collisions.

Working Principle

The XC40S-0901A0A00AB0 consists of a transmitter and receiver unit. The transmitter unit is composed of a line of infrared light-emitting diodes (LEDs). These LEDs project a continuous infrared light beam, forming a virtual curtained grid across the monitored entry point. When an object is placed between the transmitter and receiver unit, the light beam is interrupted and the receiver unit signals an alarm. The receiver unit is composed of a line of infrared photoelectric detectors. These detectors detect and analyze the light beam and the received signal is then sent to the appropriate machine control system to trigger the appropriate safety measures.

The XC40S-0901A0A00AB0 is protected from external interference by a casing and mirror system. The casing is designed to protect the LED and photoelectric detectors from dust, dirt, moisture, and other environmental factors. The mirror system further enhances the brightness of the transmitted light beam and increases the signal-to-noise ratio, allowing the system to detect small movements and angles.

The XC40S-0901A0A00AB0 is a reliable and effective light curtain than can help protect personnel and equipment from potential hazards. The light curtain is easy to install and configure and requires minimal maintenance. This makes it an ideal solution for a wide variety of industrial safety applications.
