Stainlesssteel insulationpiercing wire probe with 4 mm banana socket Key benefits Measures voltage on insulated lowvoltage wiring without stripping insulation, saving time and reducing repeated wire damage. Durable stainlesssteel tip resists corrosion and holds up to cold and temperature environments for reliable use in field and workshop testing. Designed for safe, straightforward connections to standard test leads and meters via a 4 mm banana socket. What it does and why you need it Provides a secure electrical contact by piercing insulation to reach the conductor; avoids cutting or soldering wires for quick diagnostics. Compatible with common multimeters and test leads that use 4 mm banana plugs, making integration with existing tools simple. Built for repeated use in demanding conditions where durability and consistent performance matter. Key specifications Material: hardened stainless steel construction for strength and temperature resistance Safety rating: CAT safety level — 30 VAC / 60 VDC maximum Current rating: up to 5 A Connector: 4 mm banana socket for standard banana plug compatibility Function: insulationpiercing probe / clip for voltage measurement Practical use scenarios Automotive and vehicle electrical troubleshooting: check 12 V and 24 V circuits without cutting wire insulation during diagnostics and repairs. Lowvoltage electronics and bench testing: take quick voltage readings on power supplies, batteries, and control circuits up to the rated voltage. Building and equipment maintenance: verify signals in alarm, HVAC control, and telecom lowvoltage wiring without disturbing existing terminations. Additional information Suitable as an individual tool or as a component in broader test kits designed for various applications. Intended for lowvoltage diagnostic use within the stated voltage and current limits; observe standard safety practices when measuring live circuits.
