Model KECG2742WBL-25LH specifies a 7.8-mm diameter, stands 2-mm high, and supports a wire, connector, or holder mounting.

 

Output audible signal devices include four models. The KPEG-267 is P-67 rated, features a 25.6-mm diameter and is 16-mm high. Output is 85 dB at 30 cm and operating voltage is 6 to 14 Vdc. It generates a continuous tone frequency of 2.8 kHz at -30° to +85° C in up to three feet of water. The IP-67 rated TRKPE-243 measures 14-mm in diameter and 9.5-mm high. Output is 80 dB at 30 cm with an operating voltage of 9 to 16 Vdc. It generates a continuous tone of 5 kHz. The TRIP-365 is IP-65 rated, measures 26-mm in diameter, stands 37-mm high, delivers an output of 85 dB at 100 cm, and uses an operating voltage from 5 to 28 Vdc. It generates a continuous tone of 3 kHz at -30°C to +85°C. Fourth in the lineup, the IP-65 rated TRIP-8012LA measures 24-mm in diameter and 22-mm high. Output is 97dB at 30cm, operating voltage is 6 to 18 Vdc and the component generates a continuous tone of 2.7 kHz at -20° to +80°C.
