Caterpillar 267-2145 Back-Up Alarm 87-112dB 9-32V

Cat 267-2145 Back-Up Alarm is a complete, rugged audible warning device for Caterpillar machines that sounds during reverse operation at 87–112 dB(A) and operates over a wide voltage range of 9–32 V. The alarm includes a 2-pin DT connector and a 290 mm (11.42 in) cable, and is rated for harsh environments with a temperature range of -40°C to 85°C and a pulse frequency of 1 Hz. Its compact dimensions are 4.07 in tall by 7.09 in long by 3.07 in wide, enabling straightforward mounting on many Cat machines. It is designed to be used on equipment such as asphalt pavers AP500F and AP555F, cold planers PM620/PM622/PM820/PM825/PM822/PM312/PM313/PM310, and a broad family of wheel loaders including models like 972 XE, 950GC, 966 XE, and 980 XE. The 267-2145 serves as an audible warning to nearby personnel and pedestrians when the machine reverses, supporting safety and compliance in busy job sites and reducing collision risk in loud, active environments.
