The Invisible Eye: How Infrared Door Sensors Work

Whether you are entering a grocery store or a high-tech office building, infrared (IR) sensors are likely the "invisible eye" that anticipates your arrival. Unlike radar sensors, which are excellent at detecting fast-moving objects from a distance, infrared sensors are the gold standard for presence detection and close-range safety. There are two primary types of infrared technology used in automatic doors: Active and Passive. Here is a breakdown of how they function. 1. Active Infrared (AIR) Sensors Active Infrared sensors are the most common type used for safety and threshold protection. They are called "active" because they consist of two parts: an emitter and a receiver. The Transmit-and-Receive Process The sensor constantly emits pulses of near-infrared light (invisible to the human eye) toward the ground. The Baseline: When the area is clear, the light hits the floor and reflects back to the receiver at a consistent intensity and angle. The Interruption: When...

Microwave vs. Infrared Door Sensors: Key Differences

Automatic doors provide unmatched convenience, accessibility, and efficiency in countless modern buildings. At the heart of their operation are intelligent sensors that detect presence and movement, signaling the doors to open and close. Among the most prevalent technologies used for these sensors are microwave (radar) and infrared. While both serve the common goal of automating door functions, they operate on fundamentally different principles, leading to distinct advantages and disadvantages. Understanding the key differences between microwave and infrared door sensors is crucial for selecting the right solution for specific applications. Let's break down these two sensor giants. Microwave (Radar) Motion Sensors Microwave sensors are primarily designed for  motion detection  and are often the go-to for door  activation . They operate using high-frequency radio waves. How They Work: Emission:  A microwave sensor continuously emits electromagnetic waves (microwaves)...

Why 2026 EN16005 Certified Sensors are the Key to Winning Large Commercial Tenders

In the competitive world of commercial building and industrial automation, securing large tenders often comes down to demonstrating not just capability, but also foresight and adherence to the highest standards. As we look towards 2026, one crucial factor is rapidly emerging as a non-negotiable requirement for success: EN16005 certified sensors. This isn't just about ticking a box; it's about safeguarding occupants, future-proofing installations, and ultimately, building a reputation for reliability and excellence. If your business aims to win significant commercial contracts, understanding and proactively adopting EN16005 certified sensors is paramount. What is EN16005 and Why is it So Important? EN16005 is the European standard for safety in use of power operated pedestrian doors. It sets out the essential safety requirements to prevent accidents and ensure the safe operation of automatic doors. While it originated in Europe, its principles and best practices are increasingl...
