Connecting Leads with 4 mm Safety Plugs
Product Code : SCL-PL-12403
Connecting Leads with 4 mm Safety Plugs (SKU SCL-PL-12403) is a pack of 10 flexible test leads fitted at both ends with 4 mm spring-type safety banana plugs. They link power supplies, meters and apparatus that have 4 mm sockets in school, college and electronics labs. Science Lab Supplies makes the leads in-house at its manufacturing unit, Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies them without intermediaries to schools, colleges, tender contractors and distributors.
Specifications
Both ends carry 4 mm safety banana plugs with spring contacts, and the plugs are stackable, so a second lead can plug into the first. The cable is soft and flexible, and the sturdy plugs and insulation are built for repeated use in electrical testing, electronics work and moderate to low current circuits.

Applications and Experiments for the 4 mm Safety Plug Leads
Safety plug leads connect instruments and boards that have 4 mm sockets, such as power supplies, meters and resistance boxes. Stacking lets several leads meet at one terminal when parallel branches or extra meters are added, and the safety-type plugs suit repeated connection work in school and college labs.
- Class 10 science and Class 12 physics: Ohm's law, resistors in series and parallel, and meter connections.
- B.Sc. and diploma practicals: wiring bridges, potentiometers and power supplies with 4 mm terminals.
- Electronics trainer boards and test set-ups with 4 mm sockets.
Standard Scope of Supply
The item is a pack of 10 connecting leads, each with stackable 4 mm spring-type safety banana plugs at both ends. Power supplies, meters and circuit boards with matching sockets are separate items and can be added to the same quotation when a complete bench is being equipped.
Packing, MOQ and Lead Time
Send a request for one pack or a laboratory-wide quantity, and the Science Lab Supplies quotation will list packing, delivery time and price for that number. Power supplies, meters and other school physics lab equipment in India can join the same quotation, so a whole electricity bench is priced together.
Science Lab Supplies is registered with an Importer-Exporter Code and can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. You can ask about specifications on the contact page, list items in the enquiry cart, or follow tender procedures on the lab tender page.
Frequently Asked Questions
Are the 4 mm plugs stackable?
Yes. The plugs are stackable, so a second lead can plug into the first. This helps when several connections have to meet at one socket of a meter or power supply.
What kind of work are these leads meant for?
They are meant for electrical testing, electronics applications and moderate to low current circuits, such as connecting power supplies, meters, resistance boxes and trainer boards that have 4 mm sockets.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer and not a trading house. The leads are made at its factory in the HSIIDC area of Saha, Ambala, India, where the quotations are also prepared.
Should I choose these or the alligator clip leads?
Choose the 4 mm safety plug leads for equipment with 4 mm sockets, such as meters and power supplies. The alligator clip leads, also 10 per pack, suit bare wires, component legs and screw terminals.
Related Electrical Measurement Equipment
Leads join sources, meters and components into working circuits. The items below pair with this pack on an electricity bench: a laboratory power supply, a voltmeter and an ammeter for measurements, and alligator clip leads for components without sockets. All four can be combined with the leads on one quotation.
