Speakers Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with Ole Wolff Electronics Inc or authorized distributors before purchase. Confirm that the IP67 rating meets the environmental requirements of your specific application. Ensure compatibility with existing mounting structures due to the rectangular footprint. Check for any recent revisions to the datasheet regarding terminal configurations or material specifications.

Speakers Selection Notes

Select this component when a high-output microspeaker is required in a small rectangular package. The 8-ohm impedance matches standard amplifier outputs. Consider the 1 W power rating for continuous operation limits. The IP67 rating makes it suitable for harsh environments where moisture or dust ingress is a concern. Verify that the 900 Hz to 10 kHz frequency response aligns with the target audio bandwidth.

Speakers Part Context

This part belongs to the Ole Wolff OWS series of dynamic microspeakers. The series focuses on high-efficiency drivers for portable and industrial applications. The OWS-131845W50A-8 specifically denotes the 18x13 mm size variant with top porting. Ole Wolff Electronics Inc specializes in custom and standard acoustic solutions for various electronic industries.

Speakers Replacement Considerations

Direct replacements must match the 18x13x4.5 mm dimensions and 8-ohm impedance. Competitors like Knowles offer similar microspeakers, but verify SPL and frequency response curves. Ensure the replacement maintains IP67 ratings if environmental sealing is critical. Check terminal type and polarity markings for circuit compatibility.
