Procurement Notes
Verify the specific datasheet version from Taoglas Limited or authorized distributors to confirm current manufacturing status and exact mechanical drawings. Ensure compatibility with existing enclosure designs regarding the 78mm diameter and mounting requirements. Confirm cable length and termination specifications match the system interface needs before finalizing procurement orders.
Selection Notes
Select this component when IP67 protection is mandatory for the audio transducer. The 8-ohm impedance suits standard amplifier outputs. Consider the 78mm physical size constraint and the need for high sensitivity in low-power environments. Verify that the 100 Hz to 10 kHz frequency response meets the target application's audio clarity requirements.
Part Context
This model belongs to Taoglas' miniature speaker series, engineered for durability in harsh environments. The SPKM series emphasizes compact form factors combined with industrial-grade sealing standards, targeting modern embedded audio solutions where reliability and small footprint are critical design drivers.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Taoglas technical support for equivalent alternatives if this specific model becomes unavailable.
