Features

 Refl ectance Compensated Output  4.3 mm Diameter Spot Size (0.171inch)  12.7 mm Operating Range (0.50 inch)  0.6 mv/µm Sensitivity (14 mv/mil) *These are refl ective type transducers based upon detecting the intensity of refl ected light. RC Model sensors have a pair of adjacent fi beroptic detectors in the sensor tip. Light refl ected off the target follows two separate paths back to the electronics where a ratiometric calculation provides the distance measurement which is inde- pendent of varying surface refl ectance; i.e., refl ectance compensated. 0 1 02 03 04 05 0 Increasing Gap Volts Typical RC Model Fiberoptic Cable & Sensor Tip - Actual Size A B C Ø C Side-by-Side Fiberoptics Tip Detail FEATURE mm inch Tip Outer Diameter, Ø C 4.75 0.187 Fiberoptic Diameter 4.34 0.171 Tip Length, C 38.1 1.5 Collar Length, B 15.9 0.625 Collar Diameter, Ø B 7.92 0.312 Cable Length, A 91 36 Cable Diameter, Ø A 6.86 0.275 Cable Min.

PHILTEC, INC., ANNAPOLIS, MD USA 410-757-4404 800-453-6242 e-mail sensors@philtec.com SENSOR TIP ALIGNMENT RC sensors have adjacent fi ber bundles in the face of the sensor. An alignment fl at is provided on the casing to aid with align- ment. The fl at is ground parallel to the split between the adjacent fi beroptic bundles, and located on the light transmitting side.  Refl ectance Compensated Output  Largest Standoff in the RC Series  14 mm Operating Range (0.550 inch)  600 mv/mm Sensitivity (16 mv/mil)  10 mm Standoff Distance (0.400 inch) Two Instrument Packages To Choose From This sensor can be provided as an analog or as a digital instrument. For available options and how to order go to www.philtec.com ANALOG OUTPUT A calibration chart is provided with each sensor tip giving the voltage output response to distance. There are three ways to derive accurate distance measurements: a) within the bounds of the linear range, multiply sensitivity by the change in voltage output b) create a lookup table using the XY calibration data points c) use a polynomial curve fi t to accurately map the sensor’s output function DIGITAL OUTPUT DMS units provide distance output via RS232. Gap cali- bration data is stored on board DMS units. They provide accurate distance measurements over the sensor’s entire operating range using a 24 bit internal lookup table. They have storage capacity for many additional calibrations. 3.5 (88.9) 4.0 (101.6) 6.0 (152.4) 6.5 (165) 7.0 (177.8) 2.25 (57.2) 0.190 (4.8) 0.125 (3.2) DMS DIMENSIONS

A nalog sensors are fast responding units ideal for relative motion measurements in dynamic applications:

  • DC-20 KHz is standard
  • DC-200 KHz or higher is optional
  • DC-100 Hz provides best resolution Standard analog units include:
  • Electronics with 0 to +5 VDC output
  • 3 foot long fi beroptic cable D isplacement Measurement Systems (DMS) are the best choice for absolute distance measurements, multiplexing and process control applications, with data rates up to 5,000 readings/second. Two sizes are avail- able: Standard DMS units include:
  • Electronics with RS-232 communication
  • Keypad/LCD for local operation 2.15 (54.6) 3.24 (82.4) 4.36 (110.8) 5.028 (127.7) 5.48 (139.2) 1.87 (47.6) 0.157 x 0.375 0.063 (1.6) ANALOG RC DIMENSIONS
