Overview
The Pomona 1825-0 is a solderless, stack-up banana plug designed for safe, dependable connections in test and measurement applications. Supplied in a pack of 10, this connector features an integral safety collar that insulates the wire conductor and provides strain relief. The nickel-plated zinc die-cast body with beryllium copper spring ensures low contact resistance and long service life, making it ideal for power supplies, multimeters, oscilloscopes, and bench test fixtures.
