A NAMUR sensor is a proximity sensor that operates in hazardous areas and produces two current output levels depending on the target position. Learn how NAMUR sensors differ from typical proximity sensors and see a real-world example of using them to measure shaft speed.
Dec 30, 2023 · NAMUR sensor is a 2 wire proximity sensor that is intrinsically safe for hazardous areas. Learn how it works, why it is used, and what are its pros and cons compared to normal proximity sensors.
A NAMUR sensor is a 2-wire proximity sensor that is usually powered by 8 VDC. A switch amplifier is often used to interface NAMUR sensors with a control system. Learn more
A NAMUR sensor is a non-amplified sensor that supplies two different signal levels depending upon switch state. These signal levels are low-level current. A logic interface circuit, controller, PLC, DCS, or intrinsically safe (IS) barrier is needed to read these current levels.
Learn about the different types of output for inductive sensors, such as switching, measuring, and NAMUR sensors. NAMUR sensors are two-wire sensors that generate output signals according to the NAMUR specifications for use in explosion-hazardous areas.
Oct 5, 2020 · In a nutshell, NAMUR proximity sensors were developed to ensure safety in hazardous locations. NAMUR proximity sensors are used in classified hazardous location areas that have explosive...

Apr 12, 2018 · NAMUR is a signaling standard, used primarily on proximity and limit switch devices. It outputs a current signal depending on the state of the switch. The switching spec is >2.1mA (typically but not always for NC) and <1.2mA for the opposite switch state. There is a 0.9mA deadband for noise immunity.
