Terminal blocks are modular, insulated blocks that secure two or more wires together. Terminal blocks consist of an insulating body and a clamping device. Their flexibility allows wiring to be centralized and makes it easier to maintain complex control circuits

PCB terminal blocks are modular, insulated devices that mount on printed circuit boards (PCBs) and secure two or more wires together. Some have integral pin terminals and mount through holes in the board. Others plug into PCB-mounted pin strips

Electronic bridges are used to cross from one circuit, channel, board or element over to another.

Connection heads, also referred to as thermoheads or thermocouple heads, provide a means for connecting temperature sensors and extension wires.

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.

Solderless terminals are passive conductors used to facilitate a connection that is not soldered

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices. 

RTD temperature probes convert the RTD resistance measurement to a current signal, eliminating the problems inherent in RTD signal transmission via lead resistance. 

Thermistor temperature probes sense temperature by using thermistors, devices made of semiconductor materials which exhibit a large change in resistance for a small change in temperature.

Thermocouple temperature probes are bimetallic style probes used for various temperature sensing applications.

Industrial backplanes are circuit boards that contain sockets or expansion slots for connections to other circuit boards. There two types of industrial backplanes: active and passive.

Industrial computer motherboards are printed circuit boards (PCBs) that house basic computer circuitry and vital components. They are devices into which other boards or cards are plugged.

Resistance temperature detector (RTD) temperature transmitters convert RTD resistance measurements to current signals, eliminating the problems inherent in RTD signal transmission via lead resistance.

Thermocouple temperature transmitters convert the small millivolt output of a thermocouple to a current signal (typically 4-20 mADC) that is immune to noise and voltage drops over a long distance.

Unijunction transistors (UJT) are three-terminal devices that exhibit a negative resistance characteristic
