FH49 Signal Relay Bifurcated Contact Form adopts a bifurcated contact form, which is designed to improve the reliability and stability of signal transmission. This relay belongs to the third generation of signal relays and complies with EN60950/EN41003 standards. It is suitable for fields such as power protection, automation control, and communication. The bifurcated contact form of the FH49 signal relay works simultaneously through two independent contacts, ensuring higher reliability when switching small currents and low voltages. This design not only reduces the mechanical interference between contacts but also improves the service life and stability of signal transmission. In addition, the relay supports two types, monostable and magnetic latching, and users can choose the appropriate version according to their needs. The FH49 signal relay adopts a sealed structure, which can effectively prevent the influence of environmental factors on the equipment while providing good electrical insulation performance. Its contact material is gold-plated or silver-plated, which can ensure high sensitivity and reliability in low-power signal transmission. The relay has a wide range of coil voltages, including 5V, 6V, 9V, 12V, 18V, and 24V, suitable for a variety of application scenarios. The FH49 signal relay has an overall size of 15mm×7.5mm×9.4mm. It has flexible installation methods and can be directly installed on the PCB board or installed by plugging and unplugging. Its pin spacing is 8.0-5.0mm, which conforms to the DIP packaging standard and is easy to integrate into various electronic devices. With its dual-split contact form, high reliability, and flexible installation methods, the FH49 signal relay has become an indispensable key component in industrial control, communication equipment, and automation systems.
