The Model 933A Life Cycle Tester is a cost effective, generic test platform used to perform cycling of keypads, keyboards, membranes, switches, or any product requiring fatigue testing
The system consists of a control box, air cylinder with test stand, and software installed by the user in a standard computer. It features a single analog channel used to measure contact resistance and bounce (expandable to four), and an air cylinder with a silicone rubber tip to simulate activation of a finger. The air cylinder may be supplied in various throw lengths, diameters even environmentally sealed. The control box allows for adjusting the velocity, force and acceleration of the cylinder.
A user-friendly Windows™ software environment allows the user to create test parameters for the unit under test (UUT), i.e., specified resistance, bounce time, number of cycles, allowed fails, cycles/second, etc. The configuration is then transferred to the control box for stand-alone or PC based operation.
Testing of the UUT is as simple as operating to a predefined number of cycles. During cycling the 933A may test for: resistance, contact bounce, total number of fails, total consecutive fails and then compare test results to the user specified parameters. The system may stop testing if a specified number, or consecutive number of failures of test parameters have occurred.
