BZ-CM Buzzer Expansion Box

Tohnichi BZ-CM is a high-volume buzzer expansion box designed to enhance audible and visual alerts in torque error-proofing systems, particularly for the R-CM Wireless Receiver with Interchangeable Modules. Featuring a powerful 98 dB buzzer and large LED indicators with 6.4 times the surface area of standard R-CM LEDs, this accessory ensures judgment results (pass/fail) are clearly recognizable from a distance in noisy industrial environments like assembly lines and quality control stations. Mountable on 35mm DIN rails for easy integration, it connects seamlessly to R-CM to amplify alerts, reducing errors and improving operator response times without adding significant bulk or complexity.
