Miniature reed relay in a single-in-line (SIL) package with a choice of normally open or data switching contacts capable of switching up to 200Vdc at 10W and 140Vac at 10VA. Available with 5V, 12V and 24V coils and has external magnetic shield and diode-suppressed coil options. Ideally suited for telecom, instrumentation, process control and industrial applications. Data switching contacts are especially recommended for automatic test equipment (ATE) applications.

Features:

  • Miniature single-in-line (SIL) package
  • Optional coil suppression diode is available to protect coil drive circuits
  • Available with normally open contacts
  • Available in specialist ATE version
  • External magnetic shield option available

Benefits:

  • Sub-miniature size and single-in-line configuration allows very high packing densities, minimizing space and cost
  • Designed specifically to meet the requirements of the ATE environment
  • 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

pdficon Catalog Glossary Reed Switch Terms Application Note

Reed Switch Terms Glossary
pdficon Vibration Testing and Precautions Application Note

Littelfuse tests sinusoidal vibration according to Mil. Std. 202G Method 204D Test Condition G (10 ? 2000 Hz frequency sweep at 30 G or 0.06 inch double amplitude whichever is less).
pdficon Capacitive Loads Application Note

When there is significant capacitance in a reed sensor reed relay or reed switch circuit the peak current and energy switched by the reed contacts should be considered.
pdficon Reed Switch Extended Shock Capabilities Application Note

The maximum shock specifications in the Littelfuse catalog are very conservative for most switches smaller than the DRxxxx type. T
