Optical choppers are mechanical or electronic devices that pass and then interrupt a beam of light for a known brief interval.  Optical shutters are used to control the amount of time that a light sensitive material is exposed to radiation. 

Sprayers and spray coating equipment are used to apply or dispense coatings, paints, fluids, cleaners, chemicals, powders or other industrial materials.

Spray guns and applicators form a coating by directing atomized paints, adhesives, liquids or powders toward a surface.

Saw blades are cutting implements used in conjunction with saws and other cutters.

DC powered pumps use direct current from motor, battery, or solar power to move liquids such as acids, chemicals, lubricants and oil, as well as water, wastewater, and potable water.

Sewage pumps are used to pump effluents, semi-solids and small solids in liquids.

Wastewater pumps are used in the collection of sewage, effluent, drainage and seepage water.

Grinder pumps shred solids and raise sewage to a higher elevation through pressure sewers. They shred sewage discharge into a finely ground slurry that can be sent through a small-diameter pressure pipe.

Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.

Superabrasives and diamond wheels consist of grinding wheels, abrasive saw blades, wheel dressers, single point tools and other products utilizing diamond or cubic boron nitride (CBN) abrasive grain.

Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).

Stepper motor drives power unipolar and bipolar stepper motors in full step, half step, and microstep motion control applications.

Power rectifiers are electrical devices that convert alternating current (AC) to direct current (DC). They are an integral part of telecom rectifiers for the telecommunications industry, and in battery chargers, DC power systems, and other power system devices.

RF amplifiers are devices that accept a varying input signal and produce an output signal that varies in the same way, but with larger amplitude.

DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
