It is known, that it is ideal to protect every controlled peripherial separately. DIN Rail-mounted relay interface module Finder Master Plus 39.3x integrates function of a switching and protective element into one component.

Finder Master Plus was in detail described to you in our article  Relay interface module with a fuse module. Thanks to a growing interest, we incorporated to our standard stock offer the first type from this series – 39.31.0.024.0060. Despite the fact, that Finder Master Plus series offers more than for example Finder 38.51 series, the price of the new type is even more favorable. In its basic version, the Master Plus module is without a fuse holder (type 093.63, upon order). To deploy the fusing function, all that is necessary is to simply push-in this holder into the module, what connects the fuse in series with the switched circuit.

Condition of the fuse is easily visible through a window.  At width of a relay module only 6.2 mm, it is an interface with a separated protection, occupying only a minimum space on the rail. Interconnections in a distribution box can be further simplified and be more transparent thanks to a possibility to use interconnection jumper links. Finder Master Plus 39.3x are available in several versions, EMR or SSR, at the type 39.3x.3 also with a leakage current suppression. Detailed information will provide you the Finder S39 datasheet.

0.01A, 10mV but even 2A are no problem for the AxW-K series Fujitsu relay. That´s why they´re a reliable component for a linear-undistorted transfer of diverse signals.

AxW-K relay series are well-proven 2-pole relays (DPDT) reliable switching even very small signals, already from 0,01mA/10mV DC, but they won´t be scared of 1A/30VDC (0,5A/125VAC). Reliable switching is ensured by bifurcated silver-based contacts plated by gold. As, circuits for signal processing usually consist of SMD components, neither a relay intended for such applications shoudn´t be too high. With the height of only 5 mm, AxW-K relay series meet this requirement very well and a standard DIL pitch makes their usage and PCB design easier at the same time.

In the AxW-K series can be found several types – with 1.5V – 48V coils, and also bistable (latching) types (with 1 or 2 coils). Types A3W,A5W,AL-D5W-K,A12W and A24W are kept in stock, other types we´re able to provide you upon order. Further features of the AxW-K series relays result from their construction as a classic electromagnetic relay – high isolation, galvanic isolation from a control circuit, ability to transfer small signals without distortion, resistance to various surges and other. Besides telecommunication circuits, AxW-K series relays are ideal for switching of signals from a wide range of industrial detectors and sensors, audio devices and other.

In an effort to bring the advantages of relay logic to the modern world of miniaturized devices, research groups in various parts of the world are exploring ways to develop nanoscale mechanical relays that can be used to build process controllers. Although typically slower than semiconductor logic devices, relays have the advantage of very low quiescent power and bidirectional current flow. Nanoscale relays can additionally achieve significantly higher switching rates than their normal-scale cousins. [via]

The essence of a proper and long-term operation of every device, is to use reliable components. From this point of view, relays Fujitsu are a synonym of reliability and a long lifetime.

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.

Sugar cube sized relay represent a universal 10A power relay for PCB mounting.

Electrical properties, package, pinout, price, availability/ delivery terms, all these are probably the most frequent criteria which a designer usually considers when deciding whether to use a given component. Furthermore, it is often convenient, if the given component is universal in some degree, perspective usable even in your future applications.

Relay Finder 36.11 series is a truly universal relay from more reasons: small dimensions, increased sensitivity, relatively high switching current and a wide operating temperatures range (-40 to +85° C). Beneficial are also environmentally friendly cadmium-free contacts and the RTIII protection, i.e. wash-tight. 2 versions are available – single throw (SPST-NO) and double throw (SPDT-CO). From 7 modifications with 3 to 48VDC coils, it´s easy to choose the right type for your application. An important argument to choose the 36 series is also a relatively very competitive price and a stable availability directly from our stock..  Detailed information will provide you the Finder 36 datasheet.

Fujitsu relays are known for their high reliability, excellent properties and a quality construction.

If you ever have saw opened a quality monitor, TV set, power source or other device using a relay, you could with a big likelihood find there a relay marked Fujitsu-Takamisawa. Fujitsu relays are a real synonym of reliability already for many decades. If you consider to use or you already have used Fujitsu relays in your devices, then we have for you an another reason for their purchase in a form of lower prices of selected types, for 10 % at an average.

Those are types JS-12NK, FTR-LYCA012Y, FTR-LYCA024Y and NY-12W-K. JS-12NK relays can be shortly described as a mid-power 8/10A/250VAC relay with a high isolation. Rest 3 types are narrow 5mm relays with 5-6A/250VAC contacts. All 4 types are environmentally friendly with cadmium-free contacts. To the trouble-free usage in modern devices also contributes their very low power consumption – all types have sensitive coils with a power consumption of only 120-220 mW depending on a type. Detailed information will provide you datasheets at given types. General application notes for usage of relays can be found in the Engineering reference. On the Fujitsu website you can also find replacements for the relays from other companies.

In our portfolio you can also find a DIN rail socket for the ultra slim relay Finder 34 series. It enables to use various relays thus to simply adapt an interface module to a given application.

From nowadays offer of relay interface modules, it is already no problem to choose a type meeting requirements of a given application. But if you need to change a configuration of a device, it is often convenient to change only a relay type. Series 93.01 socket enables this easily, because the protection and indication circuit is designed for a wider range of input voltages. This enables to use a 5V, 12V and 24V Finder relays 34.51 series. A green indication diode indicates presence of a control voltage and the protection circuit protects relay against reverse voltage and suppresses voltage spikes appearing at its switching off. When using 93 series socket, it is even possible to use an AC voltage to supply a DC coil of a relay.

Finder 34 series relays are ultra slim 6A relays with a sensitive DC coil. High 6kV isolation provides a safe disjunction of relay coil from contacts. Finder 34.x can be mounted directly to a PCB, via a PCB socket or to a DIN rail by means of the above mentioned socket. In some applications can also be convenient relatively short switching times – 5/3 ms.
