Panasonic buzzer EB1124 DC24V 90dB Panasonic brand new original genuine product

Product Overview:

The Panasonic buzzer EB1124 is a DC powered piezoelectric buzzer known for its high reliability, long lifespan, and stable performance. It is mainly used for equipment status prompt, alarm, operation confirmation and other occasions.

Key characteristics and parameters, the main parameters are as follows:

Parameter specification value description

Model EB1124 is the standard model of the Panasonic series

The working voltage is DC 24V rated voltage, and a 24V DC power supply is required

The sound pressure level of 90 dB is measured at a distance of 1 meter from the buzzer, and the volume is very loud enough to attract attention in noisy environments

The tone type of continuous/intermittent depends on the suffix of the model (e.g. EB1124C is continuous, EB1124P is intermittent)

Current consumption ≈ 15 mA. Typical operating current at rated voltage, with low power consumption

Sound generation method: piezoelectric type utilizes the inverse piezoelectric effect of piezoelectric ceramics to vibrate and produce sound, with long lifespan and low power consumption

Working temperature -20 ° C~+70 ° C suitable for most industrial environments

The protection level is usually IP40 dustproof design, but not waterproof. Do not use in damp or splashing environments

Installation method: Panel installation usually comes with nuts, which can be installed and fixed from the front of the equipment panel

The common wiring method for leads or terminals is two leads (red: positive pole, black: negative pole)

Main purpose:

Due to its high reliability and moderate volume, EB1124 is widely used in various devices and occasions that require sound prompts:

Industrial automation: Start, stop, and fault alarm of PLC control systems, CNC machine tools, robots, and production line equipment.

Security system: access control system, alarm control host, fire alarm system.

Medical equipment: working status prompts or warnings for medical instruments.

Office equipment: copiers, printers, shredders, etc.

Household appliances: high-end washing machines, dryers, etc. (but 24V voltage is not common in household appliances).

Precautions for use:

Correct polarity: It is necessary to connect the positive and negative poles correctly (usually the red line is connected to DC24V+, and the black line is connected to GND). Reversing the connection may cause the buzzer to malfunction or be damaged.

Voltage matching: Please ensure that the power supply voltage is DC 24V. High voltage can damage the buzzer, while low voltage may cause insufficient volume or no sound.

Installation environment: Pay attention to its protection level and avoid using it in extreme environments with high dust, oil stains, moisture, or vibration to avoid affecting its lifespan and performance.

Model suffix description

The complete model may include suffixes to distinguish different characteristics, with the most common being:

EB1124C: Represents emitting a continuous single tone.

EB1124P: Represents the intermittent "beep beep" sound, which is more eye-catching.

summary

The Panasonic EB1124 DC24V 90dB is an industrial grade buzzer with excellent performance and reliable quality. If you need to add a loud and clear sound prompt or alarm function to your device, it is a great choice. Before installation and use, please refer to its official data manual and pay attention to the correct wiring and driving method.
