FAQs
What applications benefit most from IDEC light curtains?
IDEC light curtains are widely used in automated assembly lines, robotic work cells, metalworking stations, packaging machinery, and material-handling systems where operator safety and machine guarding are essential. Their fast detection capabilities ensure hazardous motion stops immediately when a person or object enters the sensing field, reducing injury risk while maintaining efficient machine operation.
How do IDEC light curtains improve safety and productivity in industrial environments?
IDEC light curtains provide continuous, non-contact safety monitoring that eliminates the need for physical barriers, allowing operators easier access to machinery without compromising safety. Their quick response times and stable optical sensing prevent accidents while maintaining workflow efficiency. This combination helps reduce downtime, improve throughput, and increase overall system reliability.
Are IDEC light curtains easy to install and integrate into safety control systems?
Yes, IDEC designs its light curtains with simplified mounting hardware, intuitive alignment indicators, standard wiring options, and built-in diagnostics that streamline installation. They integrate seamlessly with IDEC safety relays, controllers, and safety PLCs, as well as third-party safety platforms, making them ideal for both new installations and retrofit projects.
What makes IDEC light curtains reliable in demanding industrial conditions?
IDEC light curtains use rugged housings, sealed optical components, and noise-resistant electronics that maintain accurate detection even in environments with vibration, ambient light interference, dust, or electrical noise. Their robust design ensures long-term stability and reduces false trips, resulting in safer and more predictable machine operation.
Do IDEC light curtains support different resolutions and detection ranges for various guarding needs?
Yes, IDEC offers multiple resolutions and protective heights designed for finger, hand, limb, and full-body detection. This flexibility allows engineers to select the ideal safeguarding solution for applications ranging from small precision machinery to large robotic cells and perimeter zones, ensuring compliant and effective machine protection.
Analog and Digital Control Signals: The Basics
Digital Signals
Digital signals are represented in either a true or false. There is no gray area with digital signals. An example of this might be a light switch. A light switch is either on or off. Another example of this might be a motor that is running or not running. Digital signals can be generated with both AC and DC circuits with varying voltages, currents and resistance. Some practical examples of using digital signals in an industrial environment might be if a pump is running or not running or a whether a valve is open or closed.
Analog Signals
Analog signals convey information in the form of a range. A light switch might be on or off as a digital signal, but a dimmer switch would be an analog signal. It can be on or off, but it can also be somewhere in between. A practical example of using analog signals in an industrial environment would be if there is a need to measure the level of a tank; whether it's full, empty or somewhere in between. Analog signals can take many different forms with some of the more common being a 4 to 20 milliamp signal or a 0 to 5 or 0 to 10 volt signal.
Communication
Communication in a device can either be sent or received. Whether that data is sent or received depends on the type of information. Is there a need to monitor the status of something? If so, an input needs to be received about that information. Is there a need to control something? If so, an output needs to be sent about what needs to occur. Receiving inputs and setting outputs are both things that can be accomplished by using both digital and analog signal types. Therefore, the signals are referred to as analog outputs (AO), analog inputs (AI), digital inputs (DI) or digital outputs (DO).
