PH-230Q

Speakers Overview

The PH-230Q is a horn speaker manufactured by Mallory Sonalert Products Inc., designed for audio output applications. It features an aluminum construction and operates within a resonant frequency range of 350 Hz to 7000 Hz. The device has an impedance of 8 ±2 Ω and supports an input power of 15 Watts RMS. It functions reliably in operating temperatures between -20°C and +70°C.

Speakers Feature Summary

• Aluminum horn construction for durable audio projection
• Wide resonant frequency response from 350 Hz to 7000 Hz
• High power handling capability at 15 Watts RMS

Speakers Applications

• Industrial warning systems requiring high-volume audio alerts
• Transportation vehicle signaling equipment
• Medical alarm devices needing clear audible notifications

Speakers Procurement Notes

Verify the specific mechanical dimensions against the sales outline drawing before integration, as the component measures 156mm x 132mm. Confirm that the 8 Ω impedance matches the amplifier output requirements to ensure optimal power transfer and prevent damage. Ensure the mounting environment stays within the specified -20°C to +70°C operational temperature range for reliable performance.

Speakers Selection Notes

Select this model when high sound pressure levels are required due to its horn design. It is suitable for environments where durability is critical, given the aluminum housing. Consider the 15W power rating to match source capabilities. Verify space constraints, as the unit measures 156x132mm, which is larger than standard piezoelectric buzzers.

Speakers Part Context

This component belongs to the Mallory Sonalert transducer portfolio, which includes speakers, microphones, and alarms. The brand is recognized for industrial and medical audio solutions. The PH-230Q serves as a dedicated acoustic output device, distinct from their electronic buzzer lines like the SC or MSE series, focusing on amplified sound reproduction rather than simple tone generation.

Speakers Replacement Considerations

No direct public substitute part numbers are documented for this specific horn speaker model. Replacement requires matching the 15W RMS power rating, 8 Ω impedance, and physical footprint of 156x132mm. Alternative transducers must be evaluated for similar frequency response characteristics and environmental tolerance.
