Miniature relay RM50N-3021-85-1012 electromagnetic for printed circuit board (sugar cube relays), height 15.3mm 2614658

Miniature PCB Relay – a reliable choice for your installation

This miniature electromagnetic relay, also known as a "sugar cube relay", is a compact solution for switching circuits. Designed for direct mounting on a printed circuit board (PCB), it is ideal for applications requiring space saving and high reliability. Its small dimensions (19.5 x 15.6 x 15.3 mm) and high functionality make it a versatile element in many electronic systems.

Construction and application

The RM50N-3021-85-1012 relay has a single normally closed contact (1Z), which means that the circuit is closed in the rest state. The contact withstands an AC load of 12 A at 125 V and DC – 12 A at 28 V. A 12 V DC coil provides reliable control. Thanks to the AgSnO2 alloy used in the production of the contacts, the relay is characterized by good corrosion resistance and long life. The IP64 protection class guarantees protection against dust and water splashes, which increases its durability in various environmental conditions.

This relay finds application in a wide range of devices and installations, such as:

• Building automation
• Control devices
• Alarm systems
• Switch-mode power supplies
• Laboratory equipment
• Industrial PLC controllers

Key features and benefits

• Compact dimensions: A height of only 15.3 mm allows mounting in tight spaces. This is particularly important when designing densely packed electronic systems.
• PCB mounting: Direct mounting on a printed circuit board simplifies integration with other components and speeds up the assembly process. Eliminates the need for additional brackets or connectors.
• High reliability: Made of high-quality materials and precise workmanship ensure long-lasting and trouble-free operation of the device.
• Resistance to external factors: The IP64 protection class protects against dust and moisture, which increases the durability of the relay in harsh working conditions.
• Versatility: The ability to use in AC and DC circuits with different voltage and current makes the relay a versatile element in many applications.
• AgSnO2 contact material: Provides good electrical conductivity and corrosion resistance, which translates into a longer device life.
