D2HW-BL273ML

Introduction

D2HW-BL273ML is a snap action, limit switch manufactured by Panasonic. Snap action limit switches are configured to indicate when a particular limit has been reached, and activate either a mechanical or digital alarm. They act as a physical limit to the mechanical and digital components of a machine, providing protection for each component.

Application Field

D2HW-BL273ML snap action limit switches are mainly used in mechanical and digital equipment, such as robots, robotic arms, automated production lines, control panels, elevators and escalators. In addition, these switches are also commonly used in mobile phones, computers, and other electronic products.

Working Principle

D2HW-BL273ML snap action limit switches feature a hysteresis-type operating mechanism. In this mechanism, a pair of contact springs are used. When the actuator is triggered to reach either the upper or lower limit of the physical movement, one of the contact springs is disengaged while the other is pushed in. This displacement in the spring then causes the SPDT switch to move either up or down, depending on which contact spring was disengaged. This in turn triggers a mechanical or electrical control system.

Conclusion

D2HW-BL273ML snap action, limit switches are an important component in automated systems, providing protection from mechanical and electrical damage. The hysteresis-type operating mechanism ensures that the switch will activate its control system whenever the physical limit is reached, providing reliable and efficient performance.
