Wiring Connections

Scale Factor (Sensitivity) -- The standard scale factor for the ARS-04 is 100 mV/(rad/sec). We can provide optional custom scale factors to order over a range of values. Any other desired scale factor must be specified in mV/(rad/sec) or mV/(deg/sec). Increasing scale factors beyond the standard value will result in a reduction in frequency range.

Range -- The output signal range is determined by dividing the maximum output voltage by the scale factor. A higher scale factor will result in a more limited range. A standard ARS-04 with a 100 mV/(rad/sec) scale factor and an output power voltage of ±10 V will have an angular velocity range of ± 100 rad/sec.

Input Voltages (Excitation) -- Standard input voltages of + 5/-5 Vdc to +15/-15 Vdc are used for the ARS-04. When the applications require operation from a single power source such a +12 Vdc, an ILC can be used to generate the dual voltage inputs to the sensor.

Signal Conditioning and Power Supply Requirements -- The ARS-04 may be operated without a separate power regulator or in-line signal conditioning unit if the standard customer power supply is well regulated and without noise, and if the sensor output cables are of proper impedance, not more than 15 to 20 feet in length, and not subject to induced noise from external emi sources. ATA Sensors supplies optional cables for the ARS-04E which have the proper connectors, use Teflon^® insulated wire with twisted pairs and heavy metal shielding to minimize noise. No cables are supplied for the ARS-04R.

Cables and Connectors -- Two cable connection options are offered for the ARS-04E. The cable CA-01 is specified when no ILC is used. Standard cable lengths are approximately 7 meters (23 feet) and this is supplied with the sensor mating connector on one end and un-terminated pigtail at the other to allow for the customer to add their own connection to measurement equipment.

The cable CA-02 is specified when an ILC box will be used. This is a 5.5 meter cable which goes from the sensor connector to the ILC box. The ILC box utilizes a 4-pin military specification AirBorn^® connector (male) MA-211-004-113-0000. The output side of the ILC box uses a corresponding CA-03 cable which is 1.5 meters in length, has an AirBorn^® “M” series connector at the ILC box end, and a pigtail at the other end to allow customer interface connectors to be added. Custom machined connector housing allow the connector to be locked to the ILC using screws provided.
