Testing of Electronic Switches

 

To determine the switching characteristics of electronic switches and elements, the electrical signal of the tested assembly is integrated into the testControl electronics and the testXpert testing software arranges the electrical switching contacts synchronously by the respective force and deformation data. In a hysteresis test (switching on and off), the mechanical force or the torque and the electrical switching point are determined and displayed. For torque measurement, the testing machine is expanded to include a torsion drive and sensor.

Checking the solder point on boards

 

A fully automatic testing system with a motorized X-Y table is used to determine the extrusion strength of soldered components. All testing machine sequences as well as the X-Y table testing positions are automatically controlled by testControl and testXpert. The operator "teaches" the testing position only once. In-person monitoring is not required for testing.

Function Testing on Electromagnetic Actuators

 

The force-stroke characteristic curve is checked when using proportional or switching magnets. The curve represents a function test on electromagnetic actuators and is usually the final test. The basic function properties of the actuators can be ascertained from the characteristic curve. The force-stroke characteristic and provides information as to whether the actuator is applying the required force inside its operating range at a fixed current level. The hysteresis provides information about friction resulting from the quality of the mechanical parts. 

 

The force-current characteristic curve is predominantly tested for proportional magnets and provides information as to whether the actuator is applying the required force inside a current range at a defined armature position. The ideal characteristic curve has a linear relationship between force and current around the operating point.
