Quick Disconnect Plug The 207 comes with one plug Additional plugs are available from Arroyo Instruments part number 1202 and we also offer pre wired connector assemblies for many common lasers Wired for JDSU L4 Laser Arroyo Instruments offers several different wiring harnesses for many popular lasers from JDSU LaserTel Alfalight Lumics and others Contact Arroyo Instruments for assistance in selecting the appropriate wire harness The quick disconnect plug has screw terminals for each position Simply strip off about of each wire s insulation insert into the appropriate position and tighten the screw 2110 0 Instruments 207 LaserMount User s Manual Page 5 Devices with Internal Temperature Sensors Some lasers include an internal temperature sensor typically a thermistor It is possible to use the device s internal sensor rather than the sensor in the 207 which will typically provide a higher degree of accuracy and stability On the back of the mount there is a SENSOR switch with two positions INT and EXT The INT position selects the thermistor in the 207 while the EXT position selects the sensor wired to the S and S connections of the quick disconnect interface NOTE Earth Grounding Considerations The DB 9 and DB 15 connectors are electrically connected to the housing and 8mm banana jack Depending on the wiring of your cables and instruments this may or may not p

As an example assume your lab is at 20 C and you will be operating the mount at 25 C then the operating point is 5 C above the ambient temperature and the thermal capacity would be 14W the 5 C point on the x axis 207 Thermal Capacity 25 C Ambient 20 10 0 10 20 30 40 50 60 T from Ambient C The graph assumes the fan is operational The capacity of the mount without the fan will be significantly less Also when ambient temperature is significantly away from 25 C the actual capacity will be slightly different Pl Instruments Page 12 207 LaserMount User s Manual Using the Thermistor on Standard Versions The standard version of the 207 LaserMount is equipped with a 10kQ negative temperature coefficient NTC thermistor specifically the BetaTHERM 10 1 A thermistor works by translating temperature into resistance with resistance decreasing as temperature increases hence the negative coefficient Below is the response curve of the thermistor 50000 40000 30000 20000 Resistance Q 10000 0 10 00 10 00 30 00 50 00 170 00 90 00 110 00 Temperature C Resistance vs Temperature Graph As can be seen be the graph the resistance of the thermistor drops very quickly In the typical control range 0 C to 40 C typical 10K thermistors offer good sensitivity to changes in temperature and this is the

8. range in which most 10K thermistors are typically used 10K thermistors can be used at much higher temperatures but will suffer poorer temperature stability performance because of the lower sensitivity All Arroyo temperature controllers support operation using a 10 or 100 thermistor bias which limits the upper control range to 450 or 45 respectively To minimize noise and maximize stability you should select highest current while still allowing you full operation across your required temperature range The typical setting is 100pA but your application will determine the actual needs Pl arroyo Instruments 207 LaserMount User s Manual Page 13 The Steinhart Hart Equation As can be seen from the temperature versus resistance graph above resistance varies inversely with temperature in a non linear fashion This relationship can be accurately modeled by polynomial equations and one such being the Steinhart Hart equation L A B In R N R The coefficients for the BetaTHERM 10K3A1 thermistor are A 1 12924x10 2 34108 10 0 87755 107 These are the default coefficients for Arroyo Instruments temperature controllers Using the RTD on 150 C Versions 207 150 LaserMount is equipped with RTD sensor with 0 00385 Q C sensitivity Like thermistors RTDs also function by converting temperature into resistance but unlike thermistors RTDs increase in resistance as temperature
