Scanner / Matrix - For demanding Safety Tests

Scanner / Matrix Systems
Make electrical safety tests faster, safer and more reproducible

Manual switching, error-prone wiring and long changeover times slow down your electrical safety tests. Our scanner and matrix systems take this work off your hands. They automatically route high voltage and high current to all required test points – safe, reproducible and fully traceable. This way you take hipot, insulation, protective earth and leakage current tests to the next level – in the lab, at goods-in and in production (end-of-line).

Why scanner/matrix systems?

• Automated signal routing – Test voltage and current are switched specifically to DUT pins, assemblies or device terminals – without manual reconnection.
• Significantly less changeover time – Once configured, sequences run stably. You save setup time and reduce wiring errors.
• Higher throughput in series – You test multiple measurement points in one run – ideal for series testing and EoL tests.
• Scalable with growing requirements – From a compact scanner to a modular switching matrix with many channels – matched to your current and future test scope.
• Compatible with your testers – The systems integrate into common safety testers, sequencers, PLC and test automation environments.

Typical applications

• AC/DC dielectric strength tests (hipot), insulation resistance, protective earth/ground bond, differential and leakage current measurements
• Multi-point testing on connectors, wire harnesses, power supplies, medical devices and industrial electronics
• Configurable test sequences for lab test stands and end-of-line stations

Functions & options at a glance

• Matrix and multiplexer topologies (1:n, n:1, n:n) for flexible path routing
• Expandable channel counts via modules and cascading
• Traceable calibration options and safety concepts with interlocks and discharge paths
• Control interfaces for sequencers, PLC, test automation and MES

Your benefits – directly measurable

• More tests in less time – You increase throughput without having to add staff.
• High process reliability – Reproducible switching paths and documented results safeguard your product and test quality.
• Fewer errors, lower costs – Automated switching reduces operator errors, rework and scrap.
• Future-proof test infrastructure – Modular concepts and flexible topologies prepare your test stands for new products and standards.

FAQ – key questions at a glance

Why do I need a switching matrix?

A switching matrix routes test voltage and test current specifically to the required pins and terminals – safely, without manual switching and with clearly defined, traceable sequences.

Are scanners compatible with my safety tester?

In most cases, yes. Common scanner/matrix systems offer suitable multiplexer options and interfaces for test automation. We check compatibility with your existing tester.

Can I expand the number of channels later on?

Yes. Depending on the system, via extension cards (free slots) or by cascading additional matrix modules. The controller addresses the new channels seamlessly – provided the model, resources and safety/discharge paths are designed accordingly.

How is electrical safety ensured during switching?

Through interlocked switching paths (interlocks), defined discharge paths for capacitive loads, status feedback from relay contacts and clear enable/lock logic in the controller. In addition, we recommend clearly labeled front connections and documented test sequences.

Which topologies are supported – and when should I use which?

• 1:n: one source to many points, e.g. hipot/IR testing of many terminals with a single source
• n:1: many sources to one point, e.g. selecting different sources/loads for one DUT
• n:n: freely routable crossbar for complex DUTs with variable paths, parallel sequences and rewiring without manual reconnection
