The EA2-5 is a compact signal relay manufactured by NEC (now Renesas Electronics). It's designed for a wide range of telecommunications, industrial control, and consumer electronics applications where reliable signal switching is required.

Applications

• Telecommunications equipment (e.g., line cards, switching systems)
• Industrial control systems (e.g., programmable logic controllers (PLCs), sensor interfaces)
• Consumer electronics (e.g., audio/video equipment, remote controls)
• Measurement and instrumentation equipment
• Security systems

Features

• Compact size
• High sensitivity
• Low power consumption
• High isolation voltage
• Surface mountable (SMD) option available

Benefits

• Reduced board space requirements
• Direct drive capability from logic circuits
• Energy savings
• Improved system safety
• Simplified assembly process

The EA2-5's compact size makes it ideal for applications where board space is limited. Its high sensitivity allows it to be driven directly by logic circuits, eliminating the need for additional driver components. The low power consumption of the relay helps to reduce overall system power consumption. The high isolation voltage between the coil and contacts ensures safety and prevents unwanted signal interference. Surface mountable versions are available for automated assembly.

Technical Specifications (Typical):

• Coil Voltage: 5V DC
• Contact Form: 2 Form C (DPDT)
• Contact Rating: 0.5A @ 125V AC / 1A @ 30V DC
• Coil Resistance: ~178 Ohms
• Isolation Voltage: 1500V AC
