Proximity Sensor

Safety light curtain muting is an important means of identifying goods from personnel. So, how does it achieve this? There are three methods: X-type (cross) muting with 2 photoelectric sensors, L muting with 2 photoelectric sensors, and T mode sequential muting with 4 sensors. What is safety light curtain muting? Muting is a function that […]

Have you ever encountered this problem? Your proximity sensor has been in use for a long time, its label has worn off, and it has stopped working. You want to replace it, but you’re not sure whether to choose an NPN or PNP output type. So how can you identify whether your sensor is NPN

Do you need to count vehicles entering and exiting a parking lot, or tally goods passing through conveyor belts at varying heights in a designated area? Point-to-point through-beam photoelectric sensors are a common option, yet they pose notable limitations in practical applications.  But, vehicle models and tally goods feature different heights, and improper sensor mounting—either

Imagine this: You’re looking for a safety light curtain to protect your workers from hazardous machinery, but when you search for suppliers, they tell you there are two types available: single-output and dual-output. So, how do you choose? What are the differences between these two types? Which one is more suitable? This article will answer

Want to know how far an object has moved on a lead-screw or conveyor? There are two options: proximity sensors and limit switches. Since there are two options, you might be wondering: What is the difference between these two products? Which one should I use? In this article, we will provide you with detailed information,

Imagine this: you are a manager in a production workshop and want to know the size of the liquid flow in real time, what should you do? In fact, you can consider converting the flow size into an easily measurable 4-20mA analog electrical signal. By detecting the size of the electrical signal and converting it

Are you looking for answers about what NAMUR sensors are, how they work, and what NAMUR sensors applications are?  Now here is the right and comprehensive article for you to learn. In simple terms, NAMUR output uses the current output signal level to distinguish the switch state.  The current is generally very small and is

As mentioned in our recent published blog post, inductive proximity sensors are widely used to detect metal objects, but what should you do when considering detecting glass or plastic? The answer is to use capacitive proximity sensors. Do you want to know how capacitive proximity sensors work? In this article, you will find the answer.

When we talk about proximity sensors, we always think of its output, but what exactly is the output? From a technical point of view, the output of a proximity sensor can be a transistor (PNP or NPN), a relay output, or an analog output(4-20mA for example). Today we are going to cover the difference between

Safety light curtains not only protect workers from dangerous machines in an invisible way, but also save time when frequently opening or closing guardrails manually. The first safety light curtain was developed by Erwin Sick, who subsequently founded the SICK – a well-known German sensor manufacturer. As a beginner of safety light curtains, you may

Safety light curtains are a type of protective equipment, widely used in the field of industrial automation to protect people from potential harm caused by dangerous machines, such as punching machines, cutting machines, and printing machines. When using the product, you may find it interesting that there are always two outputs, called OSSD1 and OSSD2,
