Buzzer (Cylindrical 16-dia.) M2BJ CSM M2BJ DS E 4 1 Buzzer Unit Series with Cylindrical 22-mm 16-dia. Body Lineup includes standard-volume models (80 phons, constant) and high-volume models (70 to 95 phons, variable). Intermittent or continuous sound can be selected. Refer to Safety Precautions for All Pushbutton Switches and Safety Precautions on page 5.

External Signal Selection Model (M2BJ-BH24D-DA) An external signal selection model is also available. With this model, it is possible to switch between continuous and intermittent sound using an external signal instead of the jumper. SW: M2BJ-BH24D-DA When A direction is ON (terminals 1, 2 ON): intermittent sound When B direction is ON (terminals 2, 3 ON): continuous sound B SW A Note: 1. Ensure that voltage is not applied simultaneously between terminals 1, 2, and 3. 2. Check the power supply polarity. Connecting with the polarity reversed may result in damage. 2 123
