LITTELFUSE Reed Relay DIL Package - 12V
Compact LITTELFUSE 24VDC reed relay with hermetically sealed DPST-NO contacts. UL508 recognised for industrial, security & telecom switching.
The LITTELFUSE HE700 Series reed relay is a high-reliability, miniature dual in-line (DIL) component designed for precision switching in demanding electronic applications. Its hermetically sealed contacts are completely isolated from the environment, providing immunity to dust, moisture, and atmospheric contaminants, ensuring consistent performance and long operational life. This robust design is further enhanced by a transfer moulded package that offers superior mechanical protection for the internal components.
Engineered for efficiency, this relay consumes significantly lower coil power compared to traditional electromechanical relays, making it an ideal choice for energy-sensitive circuits. The integrated coil suppression diode protects sensitive control circuitry from voltage spikes and transients generated during switching. With a broad operating temperature range from –40°C to +85°C, it is built to perform reliably in harsh industrial environments.
