Miniature relay RM50N-3021-85-1024 electromagnetic for printed circuit board (sugar cube relays), height 15.3 mm 2614660

Miniature relay for printed circuits

This miniature electromagnetic relay from the RM50N series is an ideal solution for applications requiring compact size and reliable operation. Designed for direct mounting on a printed circuit board (PCB), it is often called a "sugar cube relay" due to its small dimensions. A height of only 15.3 mm allows for use in limited space.

Characteristics and application

The RM50N-3021-85-1024 relay is characterized by a single normally closed contact (1Z), which means that in the rest state the circuit is closed. Its parameters – 12 A at 125 V AC and 12 A at 28 V DC – allow for controlling various loads. The 24 V DC coil voltage ensures compatibility with popular control systems. Thanks to the IP64 protection class, the relay is resistant to dust and water splashes, which increases its durability and reliability in various environmental conditions.

Construction and mounting

The dimensions of the relay are 19.5 x 15.6 x 15.3 mm, which makes it very compact. Direct mounting on a printed circuit board (PCB) simplifies the installation process and minimizes the need for additional mounting elements. The contact made of AgSnO2 (silver-tin-oxide) ensures good conductivity and corrosion resistance, which translates into a long device life. This relay finds application in a wide range of electronic devices, such as controllers, alarm systems, home automation and all kinds of applications requiring reliable switching of medium-power circuits.
