Miniature reed relay in a dual-in-line (DIL) package with a choice of normally open, normally open high-voltage, normally closed or changeover contacts capable of switching up to 300Vdc at 10W. Available with 5V, 12V and 24V coils and diode suppression. Magnetic shield option available. Ideally suited for security, telecom, instrumentation, process control and industrial applications.

Features:

  • Miniature dual-in-line (DIL) package
  • Optional coil suppression diode is available to protect coil drive circuits
  • Available with normally open contacts
  • External magnetic shield option available

Benefits:

  • One relay, various contact choices help to reduce space and cost without compromising flexibility
  • 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
  • Industrial equipment
  • Instrumentation

pdficon Catalog Glossary Reed Switch Terms Application Note

Reed Switch Terms Glossary
pdficon Handling of Reed Sensors Relays And Switches Application Note

When used within their capabilities Littelfuse reed sensors reed relays and reed switches provide many years of robust performance
pdficon Measuring Reed Switch Sensitivity and Contact Resistance Application Note

The purpose of this application note is to document the preferred method of reading the sensitivity and contact resistance of Littelfuse reed switches.
pdficon Inductive Load Arc Suppression Application Note

When a reed switch or reed sensor is used to control an inductive device (relay coil solenoid transformer small motor etc.)
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
