Series MH120 for mobile hydraulics applications Key-Features: - Cost-effective sensor for construction machinery - Measurement ranges from 3 to 10 m - extreme robust construction - Analog outputs: Potentiometer, 0...5 V, 0...10 V, 4...20 mA, optional redundant - teachable outputs: 0...5 V, 0...10 V, with an additional Open-Collector switching output - Digital output: CANopen, optional redundant - Linearity up to ±0.1 % of full scale - Protection class up to IP69K (suitable for close-range high pressure, high temperature spray downs) - Temperature range -20...+85 °C (optional -40 °C)

INTRODUCTION The draw wire sensors of the mobile hydraulic series MH120 were specially developed for the demanding area of construction machines and construction equipment. The sensor can be individually configured depending on the application, in which it is used. Small adhesive and abrasive particles with small grain size can easily be removed when using the open MH120 versions. Seawater resistant protective grating provide a maximum protection against larger foreign objects like tree branches. In case of applications with high safety requirements, thicker stainless-steel wire ropes are available,...

Standard: open housing + open rope bridge 52 Dependency of dimensions A, B, C from the measurement range and the rope diameter Note: when using close-range high pressure or high temperature spray downs for cleaning purposes the cable must be protected.Positionsmesstechnik

Version C1: housing with perforated plate covering + open rope bridge 60 Version C2: housing with perforated plate covering + closed rope bridge 60 Version C3: closed housing + closed rope bridge Dependency of dimensions A, B, C from the measurement range and the rope diameter

OPTIONS Option Changed cable or connector orientation Description Rope bridge points upwards: Standard: cable or connector output shows downwards K1: cable or connector output shows to the right K2: cable or connector output shows upwards K3: cable or connector output shows to the left Improved linearity Inverted output signal (only analog output) Improved linearity 0.1 % (L10) or 0.25 % (L25) The analog signal of the sensor is increasing by extracting the rope (standard). Option IN inverts the signal, i.e. the signal of the sensor declines by extracting the rope. range retracted Redundant output...

Draw wire sensors with the analogue output versions 5VT and 10VT are equipped with teachable, internal electronics, called VT-Electronics. The signals provided by the sensor's potentiometer are digitized by the VT-Electronics. This digital information is first processed by the electronics, then transformed back and given out as an analogue output signal 0 to 5 V or 0 to 10 V. The digitization offers two possibilities of adjustment, by which the sensor can be configured individually using the Squeezer: 1. Teaching of the measurement range. After a successful teaching process, the squeezer can...

Single analog signal WARNING NOTICES • Do not let the rope snap back. If the rope is retracted freely, this may lead to injuries (whiplash effect) and the device may be damaged. • Caution when unhooking and retracting the rope into the sensor. • Never exceed the specified measurement range when extracting the rope! • Do not try to open the device. The stored energy of the spring drive may lead to injuries when being mishandled. • Do not touch the rope when operating the sensor. • Avoid guiding the rope over edges or corners. Use a deflection pulley instead. • Do not operate the sensor if the...
