Product Overview
Pomona Electronics B-24-0 is a 24-inch black stacking banana plug patch cord built for bench testing, circuit patching, and lab diagnostics. Standard 4mm stackable banana plugs on both ends let you daisy-chain additional leads from a single connection point - useful when you need to monitor multiple test points without crowding a panel or binding post. Nickel-plated beryllium copper spring contacts maintain consistent tension through repeated insertion cycles.
Key Features
- Cable length: 24 inches (610 mm)
- 4mm stackable banana plug on both ends - accepts additional plugs inline or stacked
- Current rating: 15 A continuous
- Hand-held voltage rating: 30 VAC / 60 VDC max
- Hands-free voltage rating: 5,000 WVDC max
- Wire gauge: 18 AWG high-flex construction
- Contact material: nickel-plated beryllium copper spring for durable tension retention
- Insulation: polypropylene molded over plug and wire for strain relief
- Max operating temperature: +55°C (+131°F)
- Color: black
Applications
- Connecting a multimeter or oscilloscope probe lead to a binding post while stacking a second lead to the same point for simultaneous signal monitoring
- Routing power from a bench supply to a breadboard while tapping the same rail for a current measurement lead
- Setting up a hands-free high-voltage test fixture inside a closed enclosure where the 5,000 WVDC rating gives the headroom needed
- Makers and hobbyists extending jumper reach between breadboard sections or from a bench supply to a project chassis when standard jumper wires fall short
- Replacing worn or intermittent patch cords on a test bench where degraded contacts are causing erratic readings
Frequently Asked Questions
What connector type does this use, and will it fit my test equipment?
Both ends are standard 4mm banana plugs - the same format used by most bench multimeters, power supplies, oscilloscope input adapters, and function generators. If your equipment has 4mm banana jacks, this cord connects directly.
What does the stacking feature actually do?
Each plug has a rear-entry banana jack built into the back of the housing. That means a second 4mm banana plug can insert directly into the back of this plug while it is still seated in the equipment jack. You get two connections at one point without removing the first lead.
What is the difference between the hand-held and hands-free voltage ratings?
The hand-held rating (30 VAC / 60 VDC) is the safe limit when a person is holding the cord or working in contact with live conductors. The hands-free rating (5,000 WVDC) applies only in controlled, enclosed test setups where the operator is not in contact with the energized circuit. Use the hand-held rating for any open-bench work.
Is this compatible with non-banana-plug inputs like BNC or alligator clips?
Not directly. This cord requires 4mm banana jacks at both connection points. Adapters exist for BNC-to-banana and alligator-to-banana conversions, but those are not included.
Banana plug cords are one of those bench staples that disappear faster than you buy them - borrowed, lost in a drawer, or just worn out from a thousand insertions. This one is still new, and the beryllium copper springs inside will stay that way through everything you put it through next.
