Safety sensors are critical components in industrial automation and MRO applications, designed to detect potential hazards and ensure safe operation of machinery and equipment. These sensors include a variety of types such as photoelectric sensors, proximity sensors, ultrasonic sensors, and safety light curtains. They are used to monitor presence, position, distance, and motion, triggering safety protocols when abnormal conditions are detected. Key features include high sensitivity, durability in harsh environments, and compliance with international safety standards like ISO 13849 and IEC 62061. Common applications include machine guarding, conveyor systems, and robotic cell safety. Products in this category may also include emergency stop switches, safety relays, and interlock devices.
