MBS1250 / 063G1123 Pressure Sensor – 0–400 bar, 4–20 mA, M12×1 4-Pin, G 1/4A, IP67, with Integrated Pulse-Snubber

MBS1250 / 063G1123 – Heavy-Duty Pressure Sensor with Integrated Pulse-Snubber

The MBS1250 / 063G1123 is a high-performance pressure sensor designed for continuous pressure monitoring in severe hydraulic environments. With a measurement range of 0 to 400 bar and a standard 4–20 mA analog output, it integrates seamlessly with mobile controllers, industrial PLCs, and data acquisition systems, delivering dependable data for closed-loop control, load sensing, and system protection.

Measurement Performance
The sensor offers a typical accuracy of ±0.5% FS, providing reliable measurement data for critical hydraulic functions. With a response time of ≤ 1 ms, it captures transient pressure events instantly, supporting real-time control and safety interventions. The unit operates on a supply voltage of DC 8–30 V and withstands an overpressure of 1200 bar and a burst pressure of 4000 bar, offering an exceptional safety margin for high-pressure hydraulic circuits.

Integrated Pulse-Snubber for Dynamic Protection
The MBS1250 features an integrated pulse-snubber that effectively dampens destructive pressure spikes, cavitation, and hydraulic hammer effects. These conditions are common in mobile hydraulic systems during rapid valve actuation, pump start/stop cycles, and sudden load changes. The pulse-snubber significantly extends sensor service life and maintains measurement stability under pulsating flow conditions.

Durable Construction for Harsh Environments
The sensor features a stainless steel housing and wetted parts, providing excellent corrosion resistance against hydraulic fluids and environmental exposure. It operates across a media temperature range of -40°C to +125°C, suitable for both cold-climate and high-temperature engine compartment installations. High vibration resistance and enhanced EMC protection guarantee stable signal output even in the presence of heavy electrical noise.

Connectivity and Environmental Protection
The electrical interface is an M12×1 4-pin connector, ensuring a secure, vibration-resistant, and sealed wiring connection ideal for mobile equipment and industrial machinery. The pressure connection is a G 1/4A external thread, a standard hydraulic interface compatible with most manifolds. With an IP67 protection rating, the sensor is fully dust-tight and protected against temporary immersion in water.
