BEC Controls A902-1P-B1B4-82 Vacuum Switch

BEC Controls A902-1P-B1B4-82 is a compact vacuum/air-pressure proving switch designed to monitor vacuum levels in pneumatic and process-control systems and signal when a preset vacuum condition is reached. The model is listed with a 125 VAC, 10 A electrical rating and a vacuum specification of 15 inches of water column (15 WC), making it suitable for detecting vacuum presence in lines and equipment and providing a control input for downstream automation. Marketed as part of the A902 family, this switch offers a straightforward way to verify vacuum in applications such as vacuum pumps and vacuum-driven processing lines, helping ensure processes only proceed when the required vacuum level is established. The 82 suffix distinguishes this particular variant within BEC Controls’ line of air-pressure/proving switches, enabling engineers to select the exact configuration that matches their installation needs. In deploying this device, align your control system’s power and load with the 125 VAC, 10 A rating and integrate it into equipment where reliable vacuum verification improves process reliability and safety.
