Product Description

The AUTONICS SRH1 Series Solid State Relays are designed for reliable and efficient switching of AC loads in industrial automation. Featuring zero-crossing switching, compact design, and high dielectric strength, these relays provide excellent durability and noise immunity. With built-in overvoltage protection and LED operation indicators, the SRH1 series ensures safe and stable performance. These relays are widely applied in heating, lighting, motor control, and temperature regulation systems, offering a long service life without mechanical wear and maintenance.

Standard Features

  • Reliable Detection: Non-contact detection of ferrous and non-ferrous metals with high repeatability

  • Durability: Robust construction with enhanced shock and vibration resistance

  • Environment Protection: IP67 rating for water and dust resistance

  • Wiring Options: Available in cable and connector types for flexible installation

  • Output Flexibility: NPN/PNP, NO/NC outputs for wide compatibility with control systems

  • Noise Immunity: Excellent resistance to electromagnetic interference
