Sensor Description
The H6EX-A2 sensor is an Intrinsically Safe inclinometer that provides high accuracy, dual axis inclination over a
range of ±180° for Hazardous Locations. The H6EX-A2 must be used with a certified isolation barrier. It is
ATEX/IECEx/MET (US)/CSA approved for use in the following hazardous locations:
•Class I & II, Division 1
•Zone 0 & 20.
The sensor incorporates MEMS accelerometers referenced to gravity with integrated temperature compensation
over the full operating range of -40° to +85°C for absolute accuracy. It has both current and voltage analog
output options available. Each output is linear with respect to the input angle directly.
The H6EX-A2 provides two continuous, fully configurable, analog outputs. These outputs are individually
settable to current from 4mA to 20mA or voltage from 0V to 10V, are settable to any axis, and are factory
configurable to match any angle range and min/max analog values.
Hazardous Location Information
Intrinsically safe equipment is defined as “equipment which is incapable of releasing sufficient electrical or
thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmosphere
mixture in its most easily ignited concentration.”

H6EX-A2 Instructions for Safety
Putting into Service
The H6EX-A2 must be used with a certified Isolation Barrier to supply a nominal +12VDC. The H6EX-A2 has the
following entity parameters:
FIGURE 1: H6EX-A2 Control Drawing
Notes:
A. The H6EX-A2 requires two barriers for operation:
1. A barrier to supply a nominal 12VDC to the unit (pins 1 and 2).
2. A barrier to protect the two analog outputs (pins 6 and 7).

C. The H6EX-A2 ground (pin 2) and all attached barrier grounds MUST be connected together so that Vmax never exceeds its
allowed voltage.
D. Imax (or Ii) is the sum current of all attached barriers.
E. All grounding path connections should be secure, permanent, visible, and accessible. The grounding path resistance
from the farthest barrier to the grounding electrode should not exceed 1 ohm.
F. The installation must be in accordance with the National Electrical Code, NFPA 70, Articles 504 and 505, Canadian
Electrical Code C22.1 Section 18, and ANSI/ISA-RP12.06.01.
Use
The sensor is designed to measure dual-axis inclination and output an analog signal.
Assembling and Dismantling
The H6EX-A2 shall not be serviced, dismantled, or re-assembled by the user.

Maintenance
No maintenance is required.
Installation and Mounting
1. On the mounting plane, prepare surface with
three tapped holes, H1-H3 for M4/M4.5
mounting screws. H2& H3 are 3.815”
[96.9mm] from H1. See Figure 2. NOTE that
the single hole on the side with the two slots
is not meant to be used for mounting.
2. Mount inclinometer to mounting plane using
M4/M4.5 mounting screws. Use the two slots
for fine adjustments.
Default Horizontal Mount Option: Axis
Orientation
The 0° orientation for the horizontal-mount
option H6EX-A2 is a desktop, level position.
•For the X-axis, looking at the unit from
the side with the connector facing to
the right (top right of Figure 3), a
clockwise rotation from the zero
position is considered positive and a
counter-clockwise rotation from the
zero position is considered negative.
•For the Y-axis, looking at the unit from
the front with the connector facing
towards you (top left of Figure 3), a
clockwise rotation from the zero
position is considered positive and a
counter-clockwise rotation from the
zero position is considered negative.
Alternate Vertical Mount Option: Axis
Orientation
The 0° orientation for the vertical-mount option of the H6EX-A2 is a vertical position with the connector down.
•For the X-axis, looking at the unit from the top side with the connector facing down (bottom left of
Figure 3), a clockwise rotation from the zero position is considered positive and a counter-clockwise
rotation from the zero position is considered negative.
•For the Y-axis, looking at the unit from the side with the connector facing down and the mounting
surface to the left (bottom right of Figure 3), a clockwise rotation from the zero position is considered
positive and a counter-clockwise rotation from the zero position is considered negative.
