Sensing and control technology for mobile, agricultural, and industrial equipment of all types has developed considerably over time. For the reliable operation of a vehicle or piece of equipment, it is critical that the signal from a sensor actually reflects the condition the sensor is monitoring. Pepperl+Fuchs has recently launched a family of positive indication sensors designed for the harsh environmental conditions of vehicles and equipment used in the mobile equipment industry. These sensors are unique in the industry, offering an extremely durable and vibration-resistant design, a degree of protection of up to IP69K, as well as E1 approval for mobile machines and vehicles. These sensors are the only ones in the industry that allow a controller to detect a faulty sensor or cable malfunction based on a real input signal.
