SMD-Relay

Picture SMD-Relay

Molded SMD Reed Relays, suitable for all current soldering and washing methods<

Due to its flat design and small dimensions, the SMD series offers a high compactness. The pin configurations are equivalent to the standard DIP diagrams.

A SMD line sense version for telecommunication application is also available under the order designation SMD-CL-1A81-15-11M.

Characteristics

  • Standardized pinouts
  • Good price/efficiency ratio
  • Flat design
  • TTL drive possible
  • UL approved
