Controllers and sensorsInclination sensor - DST X710

The Danfoss DST X710 entry level Inclination sensors are developed to ensure a robust and high-performance solution for applications such as agricultural- and construction machines, as well as material handling equipment. These sensors are typically used in safety applications in order to keep the inclination of a machine, or just a part of it, a safety zone for working people, under control.

Danfoss DST X710 series uses contactless MEMS technology for both single and dual axis with measurement ranges up to 360°.

All sensors are designed for off-highway applications and resistant to shock and vibrations and with high electromagnetic compatibility and comes with either analogue or CAN open output.

The sensors are produced according to PL d (EN ISO 13849-1:2015), making the complete portfolio suitable for safety-critical applications.

Features

• MEMS technology for almost infinite sensor life time

• Dual axis up to ±85°, Single axis 360° (±180°)

• Output: Analogue or CANopen

• Electrical connector: AMP Superseal 6p

• 282108-1 or cable

• Accuracy: < ± 0.5% FS

• Resolution; 0.01°

• IP protection level IP67 - IPX9K with female mating connector

Controllers and sensorsPressure sensor - MBS 1250Principle of Operation

The pressure transmitter converts measured pressure into a linear temperature compensated output signal that is proportional to the transmitter supply voltage.

The output signal varies between 10 and 90% of the supply voltage. This output signal is well suited for direct connection to an A/D converter provided that the transmitter and the ratiometrically coupled A/D converter use the same voltage reference. Danfoss PLUS+1® and other microcontrollers use ratiometric A/D conversion.

Integrated Pulse Snubber

The heavy duty pressure transmitter with an integrated pulse snubber is specially suited for hydraulic applications where cavitation, liquid hammer, or pressure peaks may occur. The pressure peaks are often short but in extreme excess of the measuring range of the transmitter. The integrated pulse snubber is principally a nozzle in the passage between the measured medium and the pressure sensitive element of the transmitter.

Features• Integrated DEUTSCH DT-04 electrical connector• SAE 4, SAE 6, and G1/4 pressure connections• Six pressure ranges available• PLUS+1® Compliant• Resistant to cavitation, liquid hammer, and pressure

peaks• Overload pressure up to 3 times measuring range• Durability: >10 million cycles• Temperature compensated

• CE marked: EMC protected in accordance with EU EMC directive

• Ratiometric output signal: 10 to 90% of supply voltage• Accuracy: 0.5% full scale• For use in severe environments

• High vibration stability• IP 67 environmental sealing• Wetted parts and enclosure of stainless steel

RE series:

The R-series is an outstanding performer in a wide range of mobile hydraulic applications. Highly efficient and dependable, these rugged motors are especially suited for low flow, high pressure situations. With several bearing options these motors are a perfect fit for use in every mobile hydraulic market.

RE Series motors offer incredibly stable performance at low speeds, and perform well in a wide range of applications. They are especially well suited for low flow, high pressure applications, due to very high volumetric efficiency. Four bearing options, combined with standard mounting flanges and output shafts, allow the motor to be configured to suit nearly any application.

Target applications

• Medium-duty wheel drives

• Augers

• Mixers

• Winch drives

• Swing drives

• Grapple heads

• Feed rollers

• Broom drives and more

Features & Benefits

• High pressure shaft seal offers superior seal life and performance and eliminates need for case drain.

• Three Bearing Options allow load carrying capability of motor to be matched to application.

• Heavy-duty drive link is the most durable in its class and receives full flow lubrification to provide long life.

• Valve-in-rotor design provides cost effective, efficient distribution of oil and reduces overall motor length.

• Pressure-compensated balance plate improves volumetric efficiency at low flows and high pressure.

F-brake:

The FB series is a multi-wet-disc-brake that provides superior performance; all internal components are fully immersed and pre-filled fluid and are environmentally sealed to prevent contamination and corrosion while providing brake durability and maintaining proper holding capacity. Compact design and large holding torque along with a lower release pressure and lower free turn torque saves your space and reduces cost.

Features & Benefits

• Compact design

• Heavy-duty roller bearings support higher shaft loads and provide longer shaft seal life.

• Oil-filled cavity immerses all components providing quiet operation

• Large holding torque with lower release pressure and free turn torque
