TOW-1538L-LW100-R

Overview

The TOW-1538L-LW100-R is an omnidirectional electret microphone manufactured by PUI Audio. It features a 4 mm diameter and 2.9 mm depth with a 100 mm wire lead termination. The device operates at a voltage of 10 VDC, drawing a maximum current of 500 uA. Key electrical specifications include a sensitivity of -38 dB and an impedance of 2.2 kOhms. The component offers IP67 environmental protection and utilizes solder pin connections for circuit integration.

Feature Summary

Omnidirectional acoustic pickup pattern for uniform sound capture
IP67 rated housing for enhanced environmental resistance
Integrated 100 mm wire leads for direct connection flexibility

Applications

Consumer electronics audio input modules
Industrial control panel voice interfaces
IoT sensor nodes requiring voice activation

Procurement Notes

Verify the specific operating voltage requirements against the 10 VDC specification before integration. Confirm that the 2.2 kOhm impedance aligns with the pre-amplifier input stage design. Ensure the IP67 rating meets the environmental exposure standards of the target application enclosure. Check compatibility with the 100 mm wire lead length for mechanical fit within the assembly.

Selection Notes

Select this model when omnidirectional coverage is required in compact spaces. The 4 mm diameter allows for discreet placement in small enclosures. The high IP67 rating makes it suitable for harsh environments where dust and water resistance are critical. Consider the 10 VDC bias requirement to ensure proper power supply design.

Part Context

This component belongs to the TOW series of microphones from PUI Audio. The series focuses on robust audio sensing solutions with varied termination options. The TOW-1538L variant specifically integrates long wire leads for ease of installation in applications where surface-mount or through-hole pins are impractical.
