Eaton Industrial Sensors
Eaton Industrial Sensors are highly reliable devices designed for industrial measurement, detection, and positioning applications. They use rugged mechanical components and stable electrical contacts to minimize downtime in everything from machine control to material handling and process automation. Eaton manufactures a comprehensive family of sensing technologies including inductive, capacitive, photoelectric, ultrasonic, and limit switches. They have compact footprint designs that make integration easy in space-constrained cabinets or machinery. Most models are available with a wide range of supply voltages, output configurations, and mounting options. Sensitivity, repeat accuracy, and switching response time are all optimized for consistent performance in harsh environments.
Eaton sensors have strong housings, environmental sealing, and wide operating temperature tolerance for use in demanding conditions. Their metal and polymer housings offer excellent durability, chemical resistance, and EMC immunity against electrical interference. Dust-tight and waterproof IP67 protection ratings on most products ensure reliable operation when exposed to oils, detergents, water, or cleaning solutions. Applications include conveyor control, material level and flow detection, hydraulic cylinder position, tank fill monitoring, pump and valve actuation, safety guards, end-of-stroke limit setting, as well as general process equipment feedback.

Analog and Digital Control Signals: The Basics
Digital Signals
Digital signals are represented in either a true or false. There is no gray area with digital signals. An example of this might be a light switch. A light switch is either on or off. Another example of this might be a motor that is running or not running. Digital signals can be generated with both AC and DC circuits with varying voltages, currents and resistance. Some practical examples of using digital signals in an industrial environment might be if a pump is running or not running or a whether a valve is open or closed.
Analog Signals
Analog signals convey information in the form of a range. A light switch might be on or off as a digital signal, but a dimmer switch would be an analog signal. It can be on or off, but it can also be somewhere in between. A practical example of using analog signals in an industrial environment would be if there is a need to measure the level of a tank; whether it's full, empty or somewhere in between. Analog signals can take many different forms with some of the more common being a 4 to 20 milliamp signal or a 0 to 5 or 0 to 10 volt signal.
Communication
Communication in a device can either be sent or received. Whether that data is sent or received depends on the type of information. Is there a need to monitor the status of something? If so, an input needs to be received about that information. Is there a need to control something? If so, an output needs to be sent about what needs to occur. Receiving inputs and setting outputs are both things that can be accomplished by using both digital and analog signal types. Therefore, the signals are referred to as analog outputs (AO), analog inputs (AI), digital inputs (DI) or digital outputs (DO).
