Reliable Signal Switching Starts with the Right Relay-FH13/W13 1A Signal Relay TUV Compliant
In today’s dense electronic environments, signal integrity is not a luxury—it is a necessity. Whether you are designing industrial control systems, test and measurement equipment, security devices, or smart home modules, the component that bridges your control logic and the outside world must be precise, durable, and certified for safety.
The FH13/W13 1A Signal Relay is engineered precisely for that mission. Designed for low-level signal applications, this relay delivers consistent performance, compact footprint, and the peace of mind that comes with full TUV certification.
Certified Safety – TUV Compliance You Can Rely On
Safety standards exist to protect both the equipment and the end user. The FH13/W13 carries TUV approval, confirming that it has passed rigorous testing for insulation, creepage, clearance, and flame resistance.
For design engineers, this means:
Reduced compliance risk during system certification.
Proven dielectric strength and isolation performance.
Confidence in long-term reliability under specified operating conditions.
When your application demands international safety acceptance, the FH13/W13 removes the guesswork from component selection.
Electrical Performance Tailored for Signal Applications
The FH13/W13 is a 1 Form A (SPST-NO) relay, optimised for switching low-power analogue or digital signals. Key electrical characteristics include:
Low coil power consumption – compatible with microcontroller outputs directly, reducing external driver complexity.
High sensitivity – ensures positive actuation even with marginal drive levels.
Clear contact rating – suitable for signal loads up to 1A at specified voltages, making it ideal for logic-level switching, sensor multiplexing, and telecom signalling.
Stable contact resistance – minimises insertion loss and signal distortion, critical for precision measurement paths.
This relay does not simply “close a contact”; it maintains signal fidelity from the first operation to the millionth.
Mechanical Robustness in a Compact Package
Space on modern PCBs is always at a premium. The FH13/W13 is housed in a low-profile, industry-standard footprint that allows dense board layout without sacrificing performance.
Sealed construction – available in flux-tight or washable versions, protecting the internal mechanism during soldering and cleaning processes.
Wide operating temperature range – performs consistently across industrial temperature spans, ensuring stable operation in both hot control cabinets and cold outdoor enclosures.
High mechanical endurance – rated for millions of operations, supporting applications that require frequent cycling, such as automated testers or periodic calibration switches.
Application Versatility
The FH13/W13 fits seamlessly into a broad spectrum of designs:
Industrial automation – PLC output modules, isolation interfaces, and field signal selection.
Building automation – HVAC controllers, access control panels, and fire alarm peripherals.
Medical equipment – patient monitoring signal routing, where safety and reliability are paramount.
Test instrumentation – multiplexing sensor inputs, range switching, and calibration path selection.
Communication devices – interface switching in modems, routers, and industrial gateways.
Wherever a clean, reliable, and safe signal contact is required, the FH13/W13 delivers.
Designer-Friendly Features
Beyond specifications, the FH13/W13 offers practical advantages for the engineering team:
Standard pin-out – simplifies PCB layout and allows drop-in consideration for existing designs.
Compatible with automated assembly – tube or tape-and-reel packaging supports high-volume production.
RoHS compliance – meets modern environmental requirements without compromising performance.
Why Choose the FH13/W13 for Your Next Project?
Every relay is a promise—a promise that a command will result in a correct, safe, and repeatable action. The FH13/W13 keeps that promise through:
TUV certification – a concrete mark of safety and quality.
Consistent electrical characteristics – batch after batch.
Durable mechanical construction – built for real-world cycles.
Compact, production-friendly design – lowers total cost of ownership.
Whether you are upgrading an existing product or starting a new design from a blank schematic, the FH13/W13 Signal Relay offers a balanced blend of performance, safety, and reliability that few competitors can match.
