To use a classic electromagnetic relay or rather an SSR - that´s the question, which apparently can´t be answered expressly, but pros and cons of both technologies are well known and information are easily available. We described to you features of solid-state relays for example in the article „Semiconductor better than a conductor?“. On the other hand, classic electromagnetic relays are still perspective, their features are continuously being improved and modern relays surprise by relatively small dimensions. To advantages of electromagnetic relays belong a high resistance to various power peaks, overvoltages and other disturbances. Price is also the factor saying in favor of electromagnetic relays.
Fujitsu FTR-K1 relays are power relays with a low profile, reflecting long-term experience of company Fujitsu. FTR-K1 replaced the over 20 years used VSB series relay, with which it is pin-compatible. High switching (16A) and inrush (80A) current, isolation strength up to 10kV, coil wound with a class F wire (155°C), cadmium-free contacts and RTII sealing make FTR-K1 literally a universal relay. FTR-K1 series is available in various versions - for example with up to 120A inrush current (K1-KS), with a transparent cover (K1-RG) and also with tab terminals for a simple load connection in the application (K1T).
As a standard stock in our offer can be found types FTR-K1CK005W, FTR-K1CK012W and FTR-K1CK024W with 5, 12 and 24V coils and one change-over contact (1CO, SPDT). We´re also able to supply other versions upon a request. Detailed information will provide you the Fujitsu FTR-K1 datasheet.
