The SY100-68-A-20 is an electronic part manufactured by SMC, which is characterized by its connection lead, 2 pins, 2 meters in length, and socket. This part is most commonly used to connect two different components together in an electrical system in order to allow communications, signals and power to be transmitted between the two. The connection lead has two pins, making it a two-pin socket. The length is two meters, which allows for a substantial amount of wiring to be used when installing the part. The socket is designed to securely hold the pins in place to ensure a solid connection and prevent them from becoming loose. The part also comes with a protective covering to help protect it from any adverse conditions or wear and tear.
