mounting is usually done either using the d-style square flange mount, e- or g-style servo mounts, or one of the standard face mounts, f1 for example. consult factory for additional face mount options. 2.the shaft seal is recommended in virtually all installations. the most common exceptions are applications requiring a very low start- ing torque or those requiring operation at both high temperature and high speed. 3. non-standard index widths and multiple indices are available by special order. consult factory. 4. complementary outputs are recommended for use with line driver type (source/sink) outputs. when used with differential receivers, this combination provides a high degree of noise immunity. 5. output ics: output ics are available as either line driver (ld) or npn open collector (oc) types. open collectors require pull-up resis- tors, resulting in higher output source impedance (sink impedance is similar to that of line drivers). in general, use of a line driver style output is recommended. line drivers source or sink current and their lower impedance mean better noise immunity and faster switching times. warning: do not connect any line driver outputs directly to circuit common/ov, which may damage the driver. unused outputs should be isolated and left floating. our applications specialists would be pleased to discuss your system requirements and the compatibility of your receiving electronics with line driver type outputs. 28v/v: multi-voltage line driver (7272*): 100 ma source/sink. input voltage 5 to 28 vdc +/- 5% standard (note: v out = v in ). this driver is ttl compatible when used with 5 volt supply. supply lines are protected against overvoltage to 60 volts and reverse voltage. outputs are short circuit protected for one minute. supply current is 120 ma typical (plus load current). this is the recommended replacement for 3904r and 7406r open collector outputs with internal pullup resistors. it is also a direct replacement for any 4469, 88c30, 8830 or 26ls31 line driver 28v /5: multi-voltage line driver (7272*): 100 ma source/sink. input voltage 5 to 28 vdc +/- 5% standard, internally regulated with 5v (ttl compatible) logic out. supply lines are protected against overvolt- age to 60 volts and reverse voltage. outputs are short circuit protected for one minute. supply current is 90 ma typical (plus load current). note: limit encoder load to 2.5w max at ambient. example at 12 vdc: 2.5w/(+12vdc minus +5vdc) = 357 ma total allowed current. consult factory for your specific requirements. 15v/v: multi-voltage line driver (4469*): 100 ma source/sink. input voltage 5 to 15 vdc +/- 5% standard (note: v out = v in ). ttl compatible when used with 5 volt supply. supply lines are protected against overvoltage to 60 volts and reverse voltage. outputs are short circuit protected for one minute. supply current is 90 ma typical (plus load current). this is a direct replacement for the 4469 line driver. 28v/oc: npn open collector (3904*, 7273*). current sink of 80 ma max. current sourced by external pull- up resistor. output can be pulled up to voltage other than supply voltage (30 v max). input voltage 5 to 28 vdc + /- 5% standard. supply current is 120 ma typical. this replaces prior ics with designations of 3904, 7406, 3302, 681 and 689. 5v/ocr, 15v/ocr, 24v/ocr: open collector (3904r*, 7406r*, 7273r*): current sink of 70 ma max. includes internal pull-ups sized at approximately 100 ohms/volt. max current source is 10 ma. supply current is 100 ma typical, 120 ma with internal pull-ups. the 5v/ocr, 15v/ocr and 24v/ocr are often replaced by the 28v/v in system upgrades. 3904, 3904r, 4469, 5v/v, 5v/oc, 5v/ocr, 9v/oc: intrinsically safe line driver and open collector outputs. these drivers are specific to intrinsically safe encoders, and are installed per the appropriate control drawings listed in table 2.1 on page 48 of the specifying guide. 6. special Cs at the end of the model number is used to define a variety of non-standard features such as special shaft lengths, volt- age options, or special testing. please consult the factory to discuss your special requirements. 7. higher frequency response may be available. please consult with the factory. 8. extended temperature ratings are available in the following ranges: -40 to 70c, -40 to 85c, C20 to 105c and C40 to 105c depending on the particular model. some models can operate down to -55c. extended temperature ranges can affect other perfor- mance factors. consult with factory for more specific information. 9. mating straight plug receptacles may be ordered from the factory: for m12 use ms3116f12-10s, for m14 use ms3106f14s-6s for m14/19 use ms3116j14-19s, for m16 use ms3106f16s-1s for m18 use ms3106f18-1s, for m20 use ms3106f20-29s * products manufactured prior to april 2007 used the line driver ic number instead of voltage output in model number. e25ba e25bc e25bb (nema 34/42 compatible) not es and t
