MBS1250 / 063G1168 Hydraulic Pressure Transducer – 0–500 bar, 0.5–4.5 V Ratiometric, Deutsch DT04 4-Pin, G 1/4A, IP67, Replacement for AT74440BC / 336-16-0026

MBS1250 / 063G1168 – Heavy-Duty Hydraulic Pressure Transducer with Integrated Pulse-Snubber

The MBS1250 / 063G1168 is a high-performance hydraulic pressure transducer from the Danfoss MBS 1250 series, specifically engineered for continuous pressure monitoring in severe hydraulic environments, mobile machinery, and construction equipment. With a full-scale measurement range of 0 to 500 bar and a ratiometric output of 0.5–4.5 V, it provides dependable data for closed-loop control, load sensing, and hydraulic system protection.

Measurement Performance
The transducer offers a typical accuracy of ±0.5% FS, delivering reliable measurement data for critical hydraulic functions. With a maximum 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 4.5–5.5 V and withstands an overload pressure of 2100 bar and a burst pressure of 4000 bar, offering an exceptional safety margin for ultra-high-pressure hydraulic circuits.

Integrated Pulse-Snubber for Dynamic Protection
The MBS 1250 series is distinguished by its integrated pulse-snubber, which 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 transducer 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.

Connectivity and Environmental Protection
The electrical interface is a Deutsch DT04 4-pin connector with gold-plated pins, ensuring a secure, vibration-resistant, and sealed wiring connection ideal for mobile equipment. Pin assignments are as follows:

• Pin 1: Common (–)

• Pin 2: Supply (+)

• Pin 4: Signal output (+)

The pressure connection is a G 1/4A external thread conforming to DIN 3852-E standards. With an IP67 protection rating, the transducer is fully dust-tight and protected against temporary immersion in water.
