Installation & Operating Instructions.
Westlock 2300 Ex ia Position Monitor – ATEX / IECEx Certified.
With Mechanical Switches, Inductive Proximity Sensors or Magnum Proximity Switches.
1.0 Introduction
The 2300 Ex ia series of Position Monitors are available in two materials, Aluminum A360.2 or Stainless Steel CF8M / 316
which provide end of travel indication by the means of either electrical switch or inductive sensors mounted within the
enclosure. These are activated by cams / triggers mounted on the rotary shaft.
The enclosure construction comprises of a shaft passing through the enclosure housing and cover, when fitted with visual
indicator, and has an integral gasket seal with up to two 'O'ring seals in the bearing areas.
The enclosure has the option of up to four entries for connection to an external power source in a combination of the
following sizes; M20 x 1.5p, M25 x 1.5p, 1/2"–14NPT, 3/4"‐14 NPT, Pg13.5 or any other suitable thread that can maintain
IP6X ingress rating. Standard offering is two or four of the same thread type / size.

This equipment may be used in a CAT 1, 2 or 3 Gas and CAT 2 or 3 Dust environments with apparatus groups covering IIA,
IIB and IIC (dependent on the components fitted inside the enclosure).
The products are certified to temperature classes between T1 through to T4 or either T5 or T6 internal component
dependent. The maximum ambient temperature range is ‐40 to +*°C (dependent on enclosure material and internal
components).
NOTE – A special construction is approved to be used at ‐50°C to +*°C when used with certain inductive proximity
sensors and seal.
* The marked ambient range shall be 5 Kelvin less than the allowed ambient range of the internal devices specified in the
individual certificates.
