Inductive Sensors and Loop Detectors
Inductive sensors are non-contact devices used to detect the presence of metallic objects in industrial machinery and automation systems. These sensors operate on the principle of electromagnetic induction, generating an oscillating electromagnetic field that is disrupted when a metal target enters the sensing range. Carlo Gavazzi offers a comprehensive range of inductive sensors in various form factors, including cylindrical and rectangular housing designs, with different output configurations such as SCR, transistor (NPN/PNP), and analog outputs. Loop detectors, on the other hand, are specialized inductive devices designed for vehicle detection in traffic management and access control applications. They detect changes in inductance caused by a vehicle passing over or stopping on a loop buried in the ground, providing reliable detection for direction of travel, presence, and speed measurement.
These sensors are widely used in industrial automation for position detection, object counting, and end-of-travel sensing in conveyor systems, packaging machinery, and robotic cells. Loop detectors are essential in parking lot management, automatic barrier gates, sliding doors, and security fences, where they trigger actions based on vehicle presence. They are also deployed in traffic light control systems and toll booths for vehicle classification and counting.
The main subcategories include cylindrical inductive sensors (e.g., M8, M12, M18, M30 diameters) with sensing distances from 2mm to 40mm, and rectangular sensors for flush or non-flush mounting. Loop detectors come in single or dual-channel versions with adjustable sensitivity and frequency settings. Key article codes often follow patterns like IA12SF02NOM1 or ICB18S30NOM1 for sensors, and LD30 or LD40 for loop detectors, indicating series, housing size, sensing distance, and output type.
