Tool turrets are indexing tool holders for lathes, transfer machines, and other machine tools. They allow equipment to carry multiple cutting tools at one time and mount individual tools in the correct sequence.

Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator.

Patch panels are groups of ports used to connect lines between communications and electronic devices. Connections are made manually with small patch cords, and are easier to wire than automatic switches. Wireless patch panels are also available.

Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions.

IC sockets and headers are board-mounted female connectors that serve as carriers for integrated circuit (IC) chips.

IC package converters and adapters are electronic interconnect devices that are used to interface different types of integrated circuit (IC) sockets.

Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation.

Eye nuts (eyenuts) are fasteners with a looped head. They are designed to receive a hook or rope.

Metal sheet is metal or alloy stock supplied or available in the form of sheet or foil. Metal sheet has a thickness between 0.006" and 0.250", and is 24" (609.6 mm) or more in width.

Shaker controllers are hardware/software devices that generate one or more analog drive signals that are applied to an amplifier / shaker / test device for the purpose of creating a specified vibration environment at one or more points on a test device.

Centronics connectors are standard parallel interface devices for connecting printers and other peripherals such as portable disc drives, tape backup drives, and CD-ROM players to computers.

IC sockets and interconnect components interface or connect a microelectronic semiconductor chip to a board or larger scale device.

Fiber optic switches route an optical signal without electro-optical and opto-electrical conversions.

Abrasive sheets, rolls or pads consists of abrasive grain adhered onto the surface of a cloth, film, paper, non-woven, sponge or other backing usually with a die cut square or rectangular shape.

Grinding wheels are used for metal removal, dimensioning, and finishing. They consist of an integral shank, pin, shaft, or mandrel that drives a mounted wheel or blades.
