The OSC1520 serves as the standard output cable for compatible tachometers, enabling seamless connection to downstream equipment like meters and data loggers. Its configuration allows for both analog (voltage-based) and pulse signals to be conveyed through a single cable, enhancing versatility. The 3-pin connector ensures a secure connection at the tachometer, while the other end’s open wiring facilitates easy integration into various input terminals. Its length is optimized for usability without excess bulk.
