Low cost, compact, and lightweight. It is a general-purpose microphone compatible with IEPE!
The TYPE4160N is a free-field type 1/4 inch microphone with a frequency range of 20Hz to 20kHz. The sound pressure sensitivity, including the preamplifier, is -44dB±3dB re 1V/Pa (6.3mV/Pa). It is compatible with IEPE, allowing for direct connection to FFT analyzers and AD converters that can supply constant current. Due to its low cost, it is suitable for multi-channel measurements. 【Features】 ■ Can be directly connected to analyzers such as FFT analyzers via BNC cable ■ Enables high-precision measurements at a low cost ■ Achieves long-term stability through forced aging at high temperatures of 360℃ *For more details, please refer to the external link page or feel free to contact us.

Company information
Aco Corporation was founded in 1972, starting with the manufacturing of microphones, and in recent years has successfully produced 1/8-inch microphones. As an acoustic measurement instrument manufacturer, we have built a track record through research and development in collaboration with user companies and university research institutions. Based on this experience, we ventured into the vibration measurement sector in 1972 and have since grown into a leading company in the sensor industry. Additionally, we have achieved success in overseas sales, which began in 1976, earning a high reputation as "Aco of Sensors" in countries such as the United States, the United Kingdom, Germany, South Korea, and Taiwan. Aco's products are primarily based on measurements in living environments and cover a wide range from various devices to buildings and medical applications, playing a vital role in quality control, maintenance, management, and research and development across all sectors. In particular, in recent years, we have expanded our achievements in the automotive industry through the enhancement of system products that include peripherals and software, accurately capturing customer needs from a single product to entire systems, aiming for mutual growth and development. Furthermore, in addition to contributing to the industrial sector, we will continue to challenge ourselves to develop new technologies to improve people's lives and enhance the environment.
