Washers are disks of metal or non-metallic material placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevent leakage, isolate, prevent loosening, or distribute pressure.

Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters. They provide a storage element for transferring energy from input to output in discrete packets as required in switching power supplies, regulators and converters.

Motor starters and contactors are motor-starting devices. They combine a contactor with overload protection and are designed for starting AC or DC motors.

AC motor starters are used to turn-on and turn-off electric motors and motor-controlled equipment. They use solid-state or electromechanical technologies, and are designed for single-phase or three-phase motors.

Terminal and junction boxes are used to house electrical components and facilitate wiring. They are T-shaped or rectangular, made from a variety of materials, and available in many different sizes, sealing configurations and mounting styles.

Electronic enclosures and instrument enclosures house electronic components and instruments. They are usually designed for handheld or desktop applications.

Industrial enclosures are used to house electronic components, equipment and devices. They are designed to protect personnel from accidental injury and to prevent the ingress of environmental contaminants.

Digital readouts are specialized displays for position and dimension readings from inspection gages and linear scales, or rotary encoders on machine tools. 

Threaded rod is a fastening bar or rod threaded along its length.

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control. PACs are functionally similar to programmable logic controllers (PLC), but provide the advanced software features of personal computers (PC).

Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function. PAC systems are used in motion control, machine control, machine vision, and other industrial control applications.

Captive screws are fasteners which remain attached to a panel or parent material, even after they are disengaged from the mating panel or part. They meld with the parent via cold forming, and then fuse with the panel or part into a single entity.

Console and consolet enclosures are freestanding structures with a sloped front or top for mounting electric or electronic control components. They protect sensitive equipment such as computer monitors in harsh, wet, dirty, or dusty environments.

Operator interface enclosures are used to house industrial controls such as display screens, pushbuttons, keyboards, lights, and other operator control devices. They are usually mounted on suspension/pendant systems or pedestals.

Pushbutton enclosures are either rectangular or wedge shaped (sloped front or top surface) and have cutouts for mounting pushbuttons. They are usually mounted on walls or pedestals.
