RC-400012-DS-BX COLE HERSEE Relay Diode

Review COLE HERSEE Relay Form 12v Diode Sealed

The Cole Hersee RC-400012-DS-BX Relay is a 12V DC coil operated relay designed for various automotive and industrial applications. This heavy-duty relay is known for its reliability and durability, making it an excellent choice for those seeking a high-performance switching solution.

The RC-400012-DS-BX Relay features a latching mechanism, allowing it to stay in the last position it was switched to until manually reset. It is rated for a maximum contact rating of 10A at 277V AC or 30V DC, making it suitable for handling moderate current loads. The relay's contacts are gold-plated, ensuring long-lasting contact performance and minimizing the risk of corrosion.

This relay employs a diode for reverse polarity protection, preventing damage to the relay when inappropriate voltage polarity is applied. The diode also enables the inductive load to be switched off before the contacts open, ensuring safe and efficient operation.

The RC-400012-DS-BX Relay measures 33.6mm (L) x 23.5mm (W) x 13.4mm (H) and weighs approximately 128g. The relay body is constructed of a robust, die-cast aluminum housing, providing excellent heat dissipation and mechanical protection. The relay also comes with four mounting screws for easy installation in various applications.

In summary, the Cole Hersee RC-400012-DS-BX Relay is a high-performance, heavy-duty switching component suitable for automotive and industrial applications. Its gold-plated contacts, latching mechanism, diode protection, and robust aluminum housing make it a reliable and efficient solution for handling moderate current loads and managing inductive loads.
