Light curtains and safety mats are two of the most recognizable pieces of automation safety products found in industrial settings today. They are used to keep workers safe from hazardous machinery, and they are becoming increasingly popular as their use is being recognized, even in traditionally slower-paced manufacturing environments. The SF2C-H20-N is a safety light curtain designed for applications where space and distance between the sensor and receiver are limited. This makes it ideal for a range of automation applications, such as in cylindrical and bar-pull applications, as well as conveyors and machine tool loading/unloading.

The SF2C-H20-N offers superior safety against other light curtain designs due to its superior sensitivity and excellent beam alignment. The SF2C-H20-N’s receivers and emitter features two light curtains with 16 infrared beams spaced 25 mm apart. This design maximizes the protection area by providing both high resolution safety and wide beam coverage. The SF2C-H20-N also features application-ready functions, such as break-beam discrete logic, teachable functions, and certification to EN/IEC 61496-1 and EN/IEC 61496-2.

The working principle of the SF2C-H20-N is fairly simple. When an object passes in front of the light curtain, the beam is broken and the resulting voltage change triggers the safety relay, which shuts down the system. This type of safety is known as Type 2, which is defined by the International Electrotechnical Commission (IEC) as two-channel monitoring, using two sensors to monitor an area. If one of the channels fails, then the overall safety is compromised and the system will shut down.

The SF2C-H20-N is certified for use in a range of machine safety applications. The most common of these uses is preventing workers from entering dangerous areas of a machinery or plant. In order to do this, the light curtain must be properly installed and maintained in order to ensure it is functioning correctly. This includes checking for proper beam alignment, ensuring optimal signal quality, and regularly testing the safety functions of the light curtain.

The SF2C-H20-N is also used in automated pick and place applications. In this application, the light curtain is used as a sensor to detect object presence and can be used to feed information to a programmable logic controller (PLC). In addition to its safety-related applications, the SF2C-H20-N is also used in triggering alarms and/or starting processes in automated applications. For example, the SF2C-H20-N could trigger an alarm when an object enters a predetermined area.

In the world of automated safety products, the SF2C-H20-N is a reliable and cost-effective solution for a range of applications. Its simple design and compact form factor make it easy to install and maintain. And with its excellent sensitivity and beam alignment, it offers superior protection against hazardous machinery, making it an ideal choice for machine safety applications.
