Relays are used widely in electrical devices and installations for applications found in a broad range of industries.
Different relay types are used to meet various switching requirements and are generally installed in switchboards, industrial automation panels and even mounted directly to printed circuit boards (PCBs) in various devices. With a variety of relay types and decades of proven performance in the commercial and industrial marketplace, make the Finder range your relays of choice!
The range includes both electromechanical and solid state relay types. The electromechanical relay is of a relatively simple design and makes use of magnetic force to switch the output. They come in various types and do not require the use of heat sinks during switching.
Solid state relays on the other hand have no ‘moveable’ contacts and make use of a photocoupler to switch the output as well as to provide isolation between input and output sections of the relay. Due to its design, these relays have characteristics such as high-speed switching, negligible audible noise, and a longer electrical life (when used within specs). Solid state relays generally make use of heatsinks, especially for larger switching currents.
The Finder range includes different types of relays designed for suitability to different application requirements. This includes:
- PCB relays (34, 40 and 41 series) which are standalone compact relays with low coil consumption that are mounted to a PCB or DIN rail socket. This makes them ideal for use in electronic appliances, telecommunications, programmable controllers etc.
- Interface/Interposing relays (38 and 39 series) are commonly used with Programmable Logic Controllers (PLCs), where this relay can be used for switching loads via control through the PLC and is also used to protect the outputs of the controller from the load by providing electrical isolation
- General purpose panel relays (46, 55, 56, 60 and 62 series) are mounted or plugged-in to a specific base and used for installation to switchboards and industrial automation panels for different applications
- Power relays (65 and 66 series) are used for switching heavy current applications e.g. industrial furnaces and ovens
- Step relays (20 and 26 series) have latching contacts which remain in one state after the coil is pulsed and changes state each time the coil is pulsed. Other variants have two coils where one is pulsed for closing and the other to return contacts to original state. Used commonly in lighting applications.
Finder relays are supported by a comprehensive range of bases that are not only used to mount the relays onto DIN rail but also used to add plug-in accessories such as coil indication, timer and EMC (Electromagnetic compatibility) suppression modules.
