1/4 of 40 for sale, brand-new and used.

This auction is for a lot of seven (7) MALLORY SC628H sonalerts as shown in the photos. Four (4) are NEW and still in the sealed plastic bags inside their box, although the boxes are a bit worn from storage and I'm calling the remaining three (3) USED because they are no longer sealed in their plastic bag inside the box and one (1) of the three does not come with a box. ALSO, please note, although they do make a piercing noise, it's not as loud as I expected.

Piezoelectric Transducer, Sonalert, 6-28 VDC, 4500 Hz ±500 Hz, 68-80 dB(A) Mallory #SC628HP The Mallory Sonalert produces an audible tone by internally creating an oscillating signal which drives a piezo ceramic transducer mounted in a sound chamber. Self driven piezo ceramic transducers are superior to electromagnetic buzzers because they produce no arcing, electrical noise, or mechanical wear during operation.

ASSORTMENT OF: RECTIFERS & BRIDGES. 28 pcs. New, old stock.
