CD120 SERIES INCREMENTAL DRAW WIRE Introduction Draw wire sensor assemblies combine a rotary sensor such as an encoder with a spring-loaded retractable cable on a drum. This provides a means to translate the precision of a rotary encoder into a linear measurement. Features A full 120 inches (10 feet) of measurement capability. Wire drum is scaled so that one revolution = 1 foot of measurement. Mounting bracket and encoder position can be rotated in 90 increments to accommodate a variety of installation requirements. Applications Concrete, wood, steel sawing Mast height measurement for fork truck AGV s Extension measurement for small cranes Flood Control gates Hydraulic Cylinder Position SPECIFICATIONS Mechanical Optical Incremental Encoder in Quadrature with Index Output Signal type +/- 0.05% of full scale Linearity Range of Pulses per inch (Ref ordering block) Resolution 0.024 (0.60 mm) diameter stainless steel Cable Type 2.9 - 4.0 pounds (13 - 18 N) Cable Tension Aluminum Enclosure material Weight 4.4 pounds, (2 Kg) Electrical 100mA (no load), up to 160 mA full load Input Current 5-28 Vdc Vout=Vin Input Voltage M16, 7 pin Connector Connector M18, 10 pin Connector SCS, cable Gland Seal Mating Connector/Cable 31186-18XX, XX = cable length in feet Drum Circumference 12 inches (304.8 mm) Page 1 www.sensata.com Copyright 2019 Sensata Technologies, Inc.Enviromental IP66 with M16 or M18 connector Enclosure Protection Rating IP65 with cable Gland Seal -20C to + 85C Operating Temperature -20C to + 85C Storage Temperature Other Specifications Maximum Velocity of cable 10 m/s 2 Maximum Acceleration of Cable 7 m/s DIMENSIONS Tolerance, unless otherwise noted: All dimensions are in inches mm 120 4.72 90 3.54 192.5 7.58 127.9 2.50 3.50 5.03 68 2.67 40 21.5 1.57 .85 7.6 155 .30 6.10 110 Holes 4.33 11 39 .43 1.54 137.4 5.41 6.6 2X .26 M3 screw 2.4 A 2X .09 92 Drainage holes 4xM3 set screws DETAIL A SCALE 1 : 1 3.61 (on each side).
