Non-contact voltage detectors are a highly reliable and safe way to detect live wires and conductors without coming into contact with them. These detectors can be used in a wide range of environments due to their compact and portable design, making them perfect for working on the go.

Non-contact voltage & magnetic field indicators, also known as a voltage detector, voltage tester pens, sensors or test pens host a wide range of features to enhance the users experience, enabling easy identification of live currents and magnetic fields. Features such as LED lights are often included to indicate when the device is in contact with a live voltage, in some cases this is also accompanied with a beeping sound.

The main difference between a voltage tester and a voltage detector is that a tester will determine the presence of voltage, sometimes providing a simple “yes” or “no” indication. Whereas the detector will not only detect the presence of voltage but also provide additional important information such as voltage level and voltage type.

Magnetic field indicators are super useful tools for maintaining your equipment, checking the functionality of magnetic equipment to ensure they are operating with optimum efficiently. These indicators are predominantly used for identifying the presence and strength of magnetic fields within a multitude of environments, they are also used to help ensure safety by detecting potential harmful magnetic fields – especially in environments where sensitive electronic equipment is operating.

At RS, we offer a wide range of reliable non-contact voltage and magnetic field indicators from trusted brands such as Fluke, Martindale, and FLIR.
