Pen Voltage DetectorA non contact voltage tester, also known as a voltage detector, is an electrical tester that aids in the detection of voltage. When troubleshooting or working on a failed asset, voltage presence is useful information to have. A non contact voltage detector is the first tool you'll reach for. Non contact voltage testers operate by sensing a very small current that is capacitively coupled from the live circuit to the tester and back to ground. Non

Spring-loaded terminals offer a secure connection and make wire connections easy

Working Voltage: 3

and many other places

Neodymium cylindrical strong magnet is very  useful for hanging or holding

High-impedance buffers are included

These are Carbon Film Resistor with a value of 180 ohm 1/2W and tolerance of ±5%

These are Metal Film Resistor with a value of 22 ohm 1W and tolerance of ±5%

This sensor differs from other typical sensors as it does not require cutting the wire for measuring current

signal break-point continuous transmission

A material with excellent thermal stability is required

It is commonly found in phone accessories and PCB sockets
