What does NAMUR mount mean?
NAMUR mount means the solenoid can be mounted directly to valve actuators. Designed for double acting or spring return actuators.
What is NAMUR connection?
NAMUR is an acronym for the User Association of Automation Technology in Process Industries, which provides an industry-wide standard for automated valve technology.
What is NAMUR standard for solenoid valve?
NAMUR solenoid valve definition NAMUR solenoid valves are used to control media flow. The valve’s electric solenoid opens or closes the valve by controlling the amount of air via a pilot to the pneumatic actuator. The solenoid and actuator work in tandem to control flow speed, flow amount, and flow direction.
What is NAMUR mount solenoid valve?
A NAMUR solenoid valve is directly mounted to pneumatic actuator inlet/outlet ports. The function of a NAMUR solenoid valve is to control media flow: the valve itself is controlled by an electric solenoid, which opens or closes the valve, by controlling the amount of air thru a pilot to the pneumatic actuator.
What is NAMUR standard?
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.
What is a NAMUR device?
Answer: A NAMUR sensor is a 2-wire proximity sensor that is usually powered by 8 VDC. When the sensor detects the target, the current flow through the sensor drops to less than 1.2 mA. When the target moves away from the sensor and is not detected, the current flow increases to above 2.1 mA.
Is NAMUR Intrinsically Safe?
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 gas, dust, or fibers present. NAMUR proximity sensors are considered Intrinsically Safe.
What is NAMUR output type?
a NAMUR output sensor is a type of sensor that is trying to circumvent this issue by representing the switch states (ON and OFF) with two levels of resistance. The sensor is operated with a nominal operating voltage of 8.2 V.
How does NAMUR sensor work?
What is NAMUR in instrument?
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.
What is the standard size of a Namur Mount?

What types of Namur shafts does Moniteur devices offer?
Moniteur Devices offers two types of NAMUR shafts designed to directly interface (without a transition coupler) with the NAMUR standard accessory mounting pattern found on most of today’s actuators. The two are: Moniteur’s low profile version has the ordering codes of “5” for the 303 SS version and “7” for the 316 SS version.
What types of brackets are available for Moniteur shafts?
Brackets are available for both Moniteur low- profile and standard NAMUR shaft styles. Plated and Stainless Steel brackets for both types are kept in stock. Length Width Height Mounting Screws For Stainless Steel Bracket Kit Part Numbersreplace the “P” in the part number with an “S”. Example: BKT-NP120 becomes BKT-NS120.
