Detectors are specialized sensors designed to identify the presence, absence, or level of specific physical properties or substances. The architecture varies from optical and ultrasonic elements to chemical-sensitive layers, all encased in industrially rated housings. Technical characteristics include high sensitivity, adjustable threshold setpoints, and rapid response times. Functionally, these devices provide discrete or analog feedback to I/O modules regarding safety hazards, object positioning, or gas concentrations. As critical components in safety and quality control, detectors work alongside safety modules to trigger alarms or system shutdowns, ensuring a safe and compliant working environment in hazardous industrial locations.
