A SMarTconn terminal block contains all the elements for a robust terminating of a field/installation related wiring job and is soldered at the surface of a PCB. An example of a SMarTconn terminal block is 140-A-524-SMD. A SMarTconn connector is a receptacle (or header) soldered to the surface of PCB, and capable to receive a mating plug-in connector that is generally pre-wired. An example of a SMarTconn connector (or header) is 120-M-221-SMD. A particular SMarTconn connector is a “SMT pin strip”. A SMT pin strip is composed of a row of SMT pins held together by a strip of plastic. This product is similar to a SMarTconn header that has its protective housing removed. An example of a SMarTconn pin strip is 971-SLK-SMD. Electrical connectors and terminal blocks are terms that are often used interchangeably.
