Miniature reed relay in a single-in-line (SIL) package with a choice of normally open, normally open high-voltage or changeover contacts capable of switching up to 300Vdc at 10W. Available with 5V, 12V and 24V coils and has external magnetic shield options. Ideally suited for security, telecom, instrumentation, process control, industrial and automatic test equipment (ATE) applications.

Features:

  • Miniature single-in-line (SIL) package
  • Available with standard 5V, 12V or 24V coil options
  • High-voltage switching version available
  • Normally open and change-over contact configurations available
  • External magnetic shield option available

Benefits:

  • Single-in-line configuration allows high packing densities, minimizing space and cost
  • Lower coil power consumption than electromechanical devices
  • Hermetically sealed switching contacts are immune to their environment
  • Transfer molded package gives maximum component protection

Applications:

  • Security systems
  • Telecom equipment
  • Process control systems
  • Automatic test equipment
  • Instrumentation
