Non magnetic probes

Non Magnetic Probes Product Line


The new ECT non-magnetic probes ensure accurate, reliable, and repeatable measuring of the earth’s magnetic field and the raw rate movement on any of the three-axis without the interference of the test probes.

The ECT non-magnetic probes support typical navigation applications in smartphones or dedicated navigation devices for cars in the fast-growing MEMS/sensor market. For the development of these probes, ECT not only leveraged its long-term experience in spring probes and materials but also the comprehensive expertise within Cohu in MEMS/sensor testing. Combining this ECT is able to provide non-magnetic spring probes that meet the challenging requirements of tri-temp MEMS/sensor testing: Sensors that measure the earth’s magnetic field and the yaw rate movement must be tested in a benign environment.

To test sensors reliably without interference to the test stimulus any possible materials that might disturb the earth’s magnetic field are not allowed in the area around the device under test. In addition, since many applications are bound for the automotive market, the test probes need to withstand temperatures of -55°C up to +155°C.
