Aofan 4mm Banana Plug Test Probes with Stainless Steel Needles - Flexible Silicone Back Probes, Precision Multimeter Accessories (1 Pair Red+Black)

• 1️⃣【Universal Compatibility】Fits standard 4mm banana plug interfaces on multimeters, oscilloscopes, and automotive diagnostic tools. Seamless integration with test lead kits for electronics repair and circuit testing.
• 2️⃣【Premium Construction】Medical-grade stainless steel needles with nickel plating resist corrosion. Dual-layer insulation combines silicone flexibility (70mm) with PA plastic safety covers (12mm), rated for 30V AC/60V DC.
• 3️⃣【Precision Design】0.7mm tapered needle tip penetrates 24-28AWG wires without damage. 21mm exposed probe length ensures secure contact with IC pins, LED solder points, and micro components. 
• 4️⃣【Ergonomic Safety】Non-slip silicone handles with color-coded insulation (red/black). Rotating 360° connectors maintain lead integrity during automotive sensor testing or PCB diagnostics.
• 5️⃣【Professional Applications】Essential for automotive harness testing (CAN bus, OBD-II), SMD component measurement, and industrial equipment maintenance. Includes protective storage caps.
