Ma-Ter DR1 (type 2) (D12A01BA005001) pressure switch

Pressure switch Ma-Ter DR1 (type 2), part number D12A01BA005001 — a compact and highly reliable industrial pressure control device developed by Italian brand Ma-Ter for professional use in automation systems, heating, ventilation, hydraulics, and other engineering systems. This pressure switch helps automate equipment operation, ensuring safety, stability, and protection against emergency situations. What it is and how it works: A pressure switch is a mechanical or differential device that monitors changes in the pressure of the working medium (e.g., air, gas, or liquid) and automatically switches the electrical circuit when the pressure reaches a set point. The DR1 (type 2) series is designed for controlling low pressure differentials with precise response, making it an excellent solution for sensitive pressure control circuits. The model D12A01BA005001 is equipped with a sensitive membrane, a microswitch with a rated current of up to 5 A at 250 Vac, and a robust housing with threaded connections ensuring reliable installation in standard automation systems. The switching range of this relay is often fixed at a preset pressure difference (e.g., about 50 mbar) — optimal for controlling filtration, ventilation, and ventilation flow backpressure or differentials in hydraulic circuits. Key advantages of Ma-Ter DR1 (type 2): Accurate and stable operation — the device responds stably to pressure changes even with small differentials, ensuring timely control of actuators. Reliable circuit switching — the microswitch provides clear switching action, making the device a reliable element of the control system. Universal compatibility — suitable for heating, ventilation
