The magnetic device ensures that the test adapter remains securely locked during the test procedure.
Use cases
A magnetic interlock is particularly important when it comes to safety and efficiency during the testing process. It reliably protects the operator, especially during tests with high voltages. At the same time, it prevents the adapter from being opened accidentally during the test process, which could lead to errors. The locking mechanism can also be helpful when testing faulty assemblies. The adapter remains closed and can only be unlocked by pressing a button, so that bad parts are not accidentally mixed with good parts due to routine or hectic work.
How the magnetic lock works
Locking mechanism: The latch on an electromagnet snaps into a metal tab when the adapter is closed, similar to a door lock, and keeps the adapter securely locked. Only when the solenoid is energized does the latch retract and the adapter can be opened. This solution ensures that the adapter remains reliably closed even in the event of a fault.
Circuitry: To prevent the solenoid from overheating, an integrated control board ensures that full power is only applied when the solenoid is energized. The voltage is then reduced. The control is typically 12V, but can be switched to 24V via a jumper if required.
Safety first: For safety-critical applications, we rely on redundancy by duplicating all relevant components.
