📝Description

The HB-2232 Reed Switch with High Breakdown Voltage is specifically engineered with highly flexible blades to maximize contact gap, particularly effective at lower AT ranges. This design characteristic ensures robust performance and high breakdown voltage capabilities, making it suitable for applications demanding reliable operation under varying conditions.

Two contact options are available for the HB-2232, offering breakdown voltages of either 350V or 500V minimum. Higher Ampere Turn (AT) groups further enhance the breakdown voltage values, providing flexibility to match specific application requirements and ensuring reliable electrical isolation in high-voltage environments.

An additional advantage of the HB-2232 Reed Switch is its resilience against shock and vibration. The design allows slight blade movement when operating at lower AT bands, preventing unintended closures and maintaining consistent performance even in challenging operational conditions.

For ease of integration into diverse applications, the HB-2232 is available in various lead configurations. The cropped lead version is tailored for compact installations within smaller plastic housings, supporting direct soldering onto cables for simplified assembly. In PCB assembly, the SMD variant facilitates efficient integration through reflow soldering processes, enhancing manufacturing throughput and reliability. Moreover, vertical and horizontal mount versions accommodate through hole PCB configurations, offering flexibility in installation orientation to meet specific project requirements.

These features collectively position the HB-2232 Reed Switch as a reliable choice across industries such as aerospace, automotive electronics, and industrial controls. Its combination of high breakdown voltage capability, flexible blade design, and versatile mounting options ensures consistent performance and durability in critical applications where electrical isolation and reliability are paramount.
