K 28 WPC - 8 OHM

Speakers Overview

The Visaton K 28 WPC - 8 OHM is a miniature electromagnetic speaker designed for panel mounting. It features an oval shape with dimensions of 28 mm in length, 14 mm in width, and 5.3 mm in depth. The unit utilizes a plastic diaphragm and basket construction with solder pad termination. Key electrical specifications include an impedance of 8 Ohms, a rated power of 1 Watt, and a resonant frequency of 950 Hz. It delivers a sound pressure level of 72 dBA and operates within a temperature range of -25°C to +70°C. The component carries an IP64 rating for environmental protection.

Speakers Feature Summary

• Compact oval design suitable for space-constrained installations
• Plastic diaphragm and basket construction for durability
• IP64 rated enclosure providing dust and splash resistance

Speakers Applications

• Miniature audio output devices
• Panel-mounted indicator speakers
• Small appliance audio signaling

Speakers Procurement Notes

Verify the specific suffix and tolerance requirements against the official Visaton datasheet before ordering. Confirm that the 8 Ohm impedance matches the amplifier output stage. Ensure the mechanical cutout dimensions accommodate the 28 x 14 mm footprint and 5.3 mm depth. Check for RoHS compliance documentation if required by your manufacturing standards.

Speakers Selection Notes

Select this model when a low-profile, ruggedized speaker is needed for harsh environments due to its IP64 rating. The 1 Watt power handling is suitable for low-volume signaling rather than high-fidelity music reproduction. Consider the 950 Hz resonance frequency when designing acoustic enclosures to avoid unwanted tonal coloration at lower frequencies.

Speakers Part Context

This component belongs to the Visaton K series of miniature speakers. The 'WPC' designation typically indicates a specific construction variant involving plastic components and potentially weather-resistant properties. It is part of a broader family of small-format transducers used in industrial and consumer electronics where size constraints are critical.

Speakers Replacement Considerations

Direct substitutes must match the 8 Ohm impedance, 1 Watt rating, and similar physical dimensions (approx. 28x14mm). Verify terminal type compatibility, as this model uses solder pads. Alternative models from other manufacturers may require mechanical adaptation due to slight dimensional variances.
