Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI

Industrial air filters reduce the number of particles in the air that passes through them. 

Display filters and films are designed to filter and/or protect monitors or flat panel displays (FPD

Electrical and EMC testing services evaluate parts and products for electromagnetic compatibility (EMC), electromagnetic interference (EMI), radio frequency interference (RFI), dielectric properties, conductivity, electrostatic discharge (ESD), insulation resistance, and other electrical characteristics

Power filters are electronic circuits designed to locate and eliminate surges, harmonic transient currents, spikes, and other unwanted signals in power distribution systems and electrical equipment such as computers, television sets, and other devices

Optical windows are used to isolate different physical environments while allowing light to pass relatively unimpeded.

Foams and foam materials are industrial products made from low density elastomers, plastics, and other materials with various structures and porosities.

Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices.

Enclosure air conditioners remove the heat generated by electronic devices from the inside of cabinets or enclosures. They typically use refrigerants and include thermostatic controls to maintain programmed environmental conditions.

Plastics and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms.

Wire mesh and cloth consists of metal wires woven or knitted into a grid or screen pattern with openings determined by the mesh size or linear density of wires (wire per inch).

Modular connectors and RJ connectors are plug-in units used in many networking and telecommunications applications. Registered jack (RJ) connectors are a type of modular connector, which often have protective capabilities such as integrated filters to protect against unwanted signals or some type of magnetics to provide filtering, signal conditioning, and isolation

Industrial sealants are liquid or viscous compounds used between surfaces to contain fluids, prevent leaks, and prevent infiltration of unwanted material. They may also include compounds for filling gaps or seams.

D-subminiature or D-sub connectors are sturdy electrical connectors with a mating face shaped like the letter D. They provide polarization because male and female connectors can fit together in only one way.

Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection.
