PRO SIGNAL 4mm Banana Plug Stackable - Black

The PRO SIGNAL 4mm Banana Plug is a high-quality, stackable connector designed for professional electrical and electronic testing applications. Its innovative piggyback design incorporates a rear socket that accepts a second 4mm test lead, enabling efficient daisy-chaining of connections without the need for multiple binding posts or adaptors. This feature is invaluable for creating complex test setups, linking multiple instruments, or establishing parallel connections quickly and securely.

The plug is colour-coded red, a standard industry practice for clearly identifying positive polarity lines in DC circuits, helping to prevent incorrect connections that could lead to equipment damage or inaccurate readings. Constructed from durable materials with a robust spring-loaded contact mechanism, it ensures a reliable, low-resistance connection every time it is inserted into a standard 4mm socket.

Its compact and ergonomic design provides a secure grip for easy insertion and removal, while the stackable functionality saves space and reduces clutter on test benches and within control panels. Ideal for use in laboratories, educational institutions, and by service engineers, this banana plug is a fundamental component for building safe and efficient test and measurement environments.
