Why Choose the ABB CB1-631B Compact Buzzer?
The ABB CB1-631B is a compact black non-illuminated buzzer designed to provide audible signalling in industrial control panels, machinery and automation systems. Part of ABB's Compact pilot device range, it provides a pulsating audible output from a space-efficient panel-mounted device.
Designed for 110–130 V AC control circuits, the CB1-631B produces a pulsating sound without light. This makes it suitable for application-defined alarms, machine conditions and process notifications where an audible indication is required without a visual light signal.
The CB1-631B has a rated current of 48 mA, operates at 50/60 Hz and uses screw terminals for straightforward industrial wiring. Its IP66, IP67 and IP69K front protection, compact 30 × 30 × 55 mm construction and broad operating-temperature range support demanding industrial installations.
Key Advantages
- Pulsating audible output helps attract operator attention to application-defined conditions.
- 110–130 V AC rated operating voltage for compatible industrial control circuits.

Pulsating Audible Signalling for Industrial Control Systems
Industrial buzzers provide an audible means of communicating equipment states, process conditions and application-defined alerts to operators. The ABB CB1-631B produces a pulsating audible signal without illumination, making it suitable where an attention-getting sound is required independently of visual indication.
Its 110–130 V AC operating range, screw-terminal connection and robust front protection make the CB1-631B suitable for compatible machinery panels, operator stations and automation systems. The compact construction allows dedicated audible signalling to be added without occupying excessive panel space.
Typical Applications
- Industrial machinery control panels.
- Machine operator stations and control consoles.
- Application-defined audible alarms and warnings.
- Process and equipment status signalling.
- PLC and automation control systems.
- Manufacturing and production equipment.
- OEM automation and machine-building equipment.
