Banana Plug Connectors Leads
Banana Plug Connectors Leads (Product Code: SCL-365/081) is a flexible connecting lead with a 4 mm banana plug at each end, used to join meters, cells, keys and power supplies in school and college physics lab circuits. It is built on 18 AWG super-flexible copper wire rated to a maximum of 15 A and comes in black and red. The leads are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its physics lab equipment in India.

What Are Banana Plug Leads Used For?
Banana plug leads link cells, battery eliminators, plug keys, rheostats, ammeters and voltmeters that have 4 mm sockets, so students can wire Ohm’s law, meter bridge and potentiometer circuits quickly and rebuild them without loose wire ends. A plug pushes into its socket and pulls out cleanly, which saves practical time compared with clamping bare wire under screw terminals.
Using red for the positive side and black for the negative side makes circuit checks faster for teachers and helps students connect meters with the correct polarity — a simple habit that suits physics practical equipment for CBSE and state-board labs. Keep the current within the 15 A maximum, pull on the plug body rather than the cable, and store the leads loosely coiled so the flexible conductor is not kinked.
What to Specify When Ordering
- How many leads you need in black and how many in red.
- That your meters, keys and power supplies accept 4 mm banana plugs.
- The lead length you prefer, as length is not stated in our listing.
- The total quantity per workbench or for the whole laboratory.
Supplier
Jain Scientific Equipments Private Limited trades under the name ScienceLab and supplies these banana plug leads from Ambala, Haryana, alongside the meters, cells and resistance apparatus used in the same circuits. Schools, colleges, dealers and importers in India and international markets can place the leads and the rest of their electricity apparatus in a single enquiry. More about the company is on its company profile.

Frequently Asked Questions
What plug size do the Banana Plug Connectors Leads use?
The Banana Plug Connectors Leads use a 4 mm banana plug with a security design on both ends. Each plug has an 18 mm tip and a 51 mm overall length, so it fits the 4 mm sockets found on many lab meters, keys and power supplies.
What current can the Banana Plug Connectors Leads carry?
The Banana Plug Connectors Leads are listed for a maximum current of 15 A. They use 18 AWG super-flexible copper wire with a 4.0 mm cable outside diameter, suited to the low-voltage DC circuits built in school and college physics practicals.
Which colours are the Banana Plug Connectors Leads available in?
The Banana Plug Connectors Leads are available in black and red. Many labs order both colours so that red marks the positive side and black the negative side of a circuit, which makes polarity checks on meters quicker for students and teachers.
How long are the Banana Plug Connectors Leads?
The cable length of the Banana Plug Connectors Leads is not stated in our listing. Tell us the length and quantity you need through the contact page, and the length that can be supplied will be confirmed in your quotation.
Who supplies the Banana Plug Connectors Leads?
The Banana Plug Connectors Leads are supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab and is based in Ambala, Haryana, India. The company supplies them together with other physics lab apparatus to buyers in India and international markets.
Can the Banana Plug Connectors Leads be ordered in bulk?
Yes, the Banana Plug Connectors Leads can be quoted in bulk for school labs, colleges, dealers and tenders. Send the quantity in each colour, your delivery location and any other apparatus you need, and one quotation can cover the complete order.
