359500 FINDER Relay

Review FINDER Vintage Electromagnetic Relay 1970s Used Information Please

The Finder 359500 and 358500 relays, manufactured in the 1970s, are time-tested components that have served various industrial automation applications with great reliability. These electromechanical relays are designed to operate with a coil voltage of 120V AC or 240V AC, making them suitable for use in a wide range of electrical systems.

The Finder 359500 is a single-pole double-throw (SPDT) relay, which means it can switch one electrical contact between two alternative contacts. It comes with a silver-plated contact set that ensures low contact resistance, providing efficient current flow and reducing electrical wear. The contacts are rated for a maximum current of 10 amperes and a maximum operating voltage of 277V AC. The relay also features a mechanical latching mechanism that retains the contact position even after the coil voltage is removed.

The Finder 358500, on the other hand, is a double-pole double-throw (DPDT) relay, which can switch two contacts simultaneously. Like the 359500, this relay operates on a 120V AC or 240V AC coil voltage and has a silver-plated contact set rated for a maximum current of 10 amperes and a maximum operating voltage of 277V AC. The DPDT design allows for the independent switching of two contacts, making it a versatile component in various control systems.

Both the Finder 359500 and 358500 relays have a contact rating of 250 million operations, indicating their robustness and longevity. Their compact size, 32mm x 22mm x 11.5mm for the SPDT and 43mm x 22mm x 16mm for the DPDT, allows for easy integration into limited spaces in control panels. The relays also come with a clear plastic cover, which protects the contacts from dust and debris and makes their status easily observable with the help of a status indicator light.

In summary, the Finder 359500 and 358500 relays, manufactured in the 1970s, are reliable and versatile components designed for various industrial automation applications. Their robust construction, long-lasting contact set, and compact size make them an excellent choice for switching low to medium currents in electrical systems.
