GENERAL INFORMATION
The VPX Valve Position Indicator is designed specifically for use in
potentially hazardous locations where explosive gases or dusts may be present.
To comply with explosion proof requirements the VPX has flame paths within the
housing, which cool any explosion below the ignition temperature before it
reach explosive gases or dusts in the surrounding atmosphere. Flame paths on
the VPX are 1) an extended shaft between the switch cavity and head and 2) the
cover-housing flange joint.
ENVIRONMENTAL PROTECTION
The VPX Valve Position Indicator is often ideal for outdoor use or in
potentially adverse environments. The enclosure is sealed for protection
against corrosion, water, dust and oil as defined in UL 50E to enclosure types
4, 4X, 6, and 13 as well as to IP66 and IP67 as defined in IEC 60529. An
ingress protection rating of IP66 was confirmed according to IEC 60079-0 along
with the hazardous location approvals. A rating of IP67 was confirmed by
Honeywell according to IEC 60529.
The equipment has a non-conducting coating and may generate an ignition-
capable level of electrostatic charges under certain conditions. The user
should ensure that the equipment is not installed in a location where it may
be subjected to external conditions (such as high pressure steam) that might
cause a build up of electrostatic charges on non-conducting surfaces.

INTRINSICALLY SAFE PROXIMITY SWITCHES
A VPX equipped with proximity switches is considered intrinsically safe when
used with an appropriate switching amplifier, also referred to as an
associated apparatus, which complies with EN 60947-5-6:2000 or IEC
60947-5-6:1999. The amplifier contains a dc source to supply the control
circuit and is controlled by the variable internal resistance of the proximity
switch. This amplifier is placed outside of the hazardous area. A diagram of
the typical installation is shown in Figure 3.
Cable capacitance, Ccable, plus intrinsically safe equipment capacitance, Ci,
must be less than the marked capacitance, CO, shown on any associated
apparatus used. The same applies for 4 sps.honeywell.com/ast
inductance (Lcable, Li and Lo, respectively). Where the cable capacitance and
inductance per foot are not known, the following values shall be used: Ccable
= 200 pF/m., Lcable = 1 H/m.
The associated apparatus output current must be limited by a resistor such
that the output voltage-current plot is a straight line drawn between open-
circuit voltage and short-circuit current. The associated apparatus must be
installed in accordance with its manufacturer’s control drawing. When required
by the manufacturer’s control drawing, the associated apparatus must be
connected to a suitable ground electrode per local installation codes, as
applicable. The resistance of the ground path must be less than 1 Ohm.
Associated apparatus must not be
MICRO SWITCH VPX Series
ISSUE M 32312068
used in combination unless permitted by the associated apparatus certification. Control equipment must not use or generate more than 250 V rms or dc with respect to earth. Where multiple circuits extend from the same piece of intrinsically safe equipment to the associated apparatus, they must be installed in separate cables or in one cable having suitable insulation. Installation must be done in accordance with all local codes.
