Kelvin Test Pins & Fixture Kits

Kelvin test pins, modules & fixture kits for the testing of transformers, chokes, relays, solenoids and cable harnesses

KWP Series

Kelvin Pins

A twin-terminal socket pin providing a two point contact onto a single lead, pin or terminal. This method allows a high quality and effective 4-pole/kelvin connection, and with suitable equipment attached, will enable the taking of accurate resistance & impedance measurements.

Available in two sizes, the open construction and the simple fitment method of this range allows quick installation into your test block. The high quality of materials used in manufacturing this product range allows durability and a reliable test contact for a wide range of component lead diameters, typically 0.5mm to 1.3mm.

KWC Series

SMD component test jigs

A brand new solution to fast testing of many configurations of SMD wound components.
This range of jigs features:

  • Zero insertion force connection which eliminates lead bending
  • Every lead has two separate connections which allows a kelvin test, if required
  • Locking lever system prevents the component under test jumping out. The simplicity of the jig allows for a reduced handling time when open
  • A pneumatically operated version is also available; please call us for more information

This type of jig is built to your unique requirements. Please contact us with your enquiry.

KWF Series

Fixture Kits

Transformer test fixture kits, which incorporate KWP kelvin pins, are suitable for use with Voltech's Universal Fixture and for standalone testing. Each kit is ideal for users that have the facilities to customise their own test fixtures.

The kit of parts include enough KWP kelvin pins to test wound components with up to 10 pins.
