Rotary Solenoids are electro-mechanical devices which provide rotational movement at specific degree angles, they actuate clockwise or counter-clockwise based on application requirements. Rotary solenoids are incredibly robust, the maintenance-free design provides durable and consistent performance over time.

Five of NSF Controls’ rotary solenoids are designed with an elongated coil with 30% more copper than standard solenoids. As a result, the increased number of wire turns creates a stronger magnetic field when current passes through it enabling the solenoid to deliver additional torque without overheating.

Solenoids are designed to eliminate costly mechanical linkages with their precise controls and quick responses. NSF Controls can also supply mounting brackets for solenoids, special connectors, and complete assemblies making integrating our solenoid into your design quick and simple.

Armature covers are available on all sizes of rotary solenoids. Their primary function is to prevent adjacent components or wires from interfering with the motion of the solenoid. They also provide an additional layer of protection in environments that are prone to dirt or dust. The armature cover acts as a barrier, preventing particles from entering the solenoid and potentially causing operational issues or damage.

Tapped holes are standard in the armature plate for mounting purposes however, they can be replaced with drive pins or threaded mounting stud. The advantage of armature drive pins aside from power take-off, is that they can be used as adaptors for levers and bars. So when the armature drive pin rotates, the lever or bar connected to it moves back and forth, producing linear motion.

A threaded mounting stud can also replace the tapped holes. These are commonly used to allow an additional plate to be attached for instance a diverter.

Temperature
*Max coil temperature 180°c assuming coil temp rise of 60°/80°c under continuous duty conditions. Special windings and lead wires may be required.

Stroke
Choose clockwise or counter-clockwise stroke as viewed from the armature end of the solenoid.
Closely match the solenoid’s stroke length to the required stroke of the application, to ensure the solenoid’s armature fully energizes, optimizing torque and overall performance.

Axial Stroke & Dimensions
Axial Stroke is the linear distance that the armature travels when the solenoid is energised.  This means that additional space must be accounted for in the space available for the solenoid.

Life Ratings
Rotary solenoids are laboratory tested under spring load conditions at 25% duty cycle at 20°C ambient temperature to determine life ratings. Rotary solenoids are rated for 1 million actuations.
Actual life, however, is greatly affected by the application and environmental factors such as exposure to extreme temperatures, dirt, dust, etc. Depending on these factors, can provide up to 20 million actuations.

Long Life Versions
Endurance Engineered models incorporating alternative bearings hardened plating in long life versions provide 50 million actuations.
Long life models provide approximately 90% of the charted torque.
