Miniature relay RM50N-3011-85-1005 electromagnetic for printed circuit board (sugar cube relays), height 15.3 mm 2614645

Compact relay for PCB mounting

The RM50N-3011-85-1005 electromagnetic relay is a miniature device designed for direct mounting on a printed circuit board (PCB). Its compact dimensions – 19.5 x 15.6 x 15.3 mm – make it an ideal solution where space is limited. This is a so-called "sugar cube" relay, popular due to its small size and versatility.

Construction and electrical parameters

This relay has a single pole single throw (SPST) contact, which means it can be used to switch circuits on or off. The output is designed to work with a load of up to 12A at 125V AC or 12A at 28V DC. The 5V DC coil consumes relatively little power. The contacts are made of AgSnO2 (silver-tin-oxide), which ensures good conductivity and corrosion resistance. The coil leads (A1-A2) and the SPST contact (11-12-14) facilitate connection to the circuit.

Application and design features

The RM50N-3011-85-1005 relay finds application in a wide range of electronic devices, such as controllers, home automation, measuring instruments and security systems. The IP64 protection class guarantees resistance to the ingress of solids and splashing water, which increases reliability in harsh working conditions. Direct mounting on the PCB eliminates the need for additional mounting elements and simplifies the device design. This makes installation faster and more economical.
