The power inputs (pins b and c) require voltage range of 9-36V at the sensor input. This galvanically-
isolated input has reverse-polarity protection, as well as overcurrent protection.
The ANALOG ground line (Pin N) is the common mode voltage reference for the differential signal lines
(pins A-B, D-E, and G-H). It also serves as the reference ground for the range voltage signals (pins K, L,
and M).
The calibration (CAL) input (pins V and W) is differential, with a +/-15V range. The common mode
reference for these signals is ANALOG ground (pin N).
EpiSensor2 Cabling
The standard cable for the EpiSensor2 is shown in Figure 2. This 6 meter long cable (PN: “Epi2.0 320001-
6”) connects to the sensor and to the digitizer. The 10-shell plug in the Y-extension, at the digitizer end,
is dedicated to the isolated RS-232 connection.
Kinemetrics can also supply a simple RS-232 connection cable (PN “Epi2.0 320002-1.5). It connects, as
shown in Figure 3, to the 10-shell plug.
Among other cable options are ones without the RS-232 takeout. This can be used when RS-232 control
is not desired, or when the cable run is beyond the practical limit of RS-232 communications (typically
15 meters).
Kinemetrics can also supply “pigtailed” (connectorless) cables. The maximum cable length is 125 meters,
owing to limitations related to digitizer power sourcing (mainly its voltage) and series resistance in the
power lines contained within the cabling. Operating power for the sensor is generally expected to come
from the digitizer (via pins b and c).
The connections within the standard cable (PN: “Epi2.0 320001-6.”) are listed in Table 2.
For users wishing to create their own cables, Kinemetrics can supply a standard, right-angle, solder-cup,
plug (with cable clamp) that will connect directly to the EpiSensor2. The commercial part number for
this item is Souriau
851-08EC16-26S50-44
. This plug, and the connection details in Table 1, are all that
users will need to make connection to the sensor.
Please contact Kinemetrics to discuss specific cable requirements.
