MECHANICAL IMPLEMENTATION

All products based on the P40Agile platform have common hardware architecture. The hardware comprises two
main parts; the cradle and the housing.
The cradle consists of the front panel which is attached to a carrier board into which all of the hardware boards
and modules are connected. The products have been designed such that all the boards and modules comprising
the product are fixed into the cradle and are not intended to be removed or inserted after the product has left the
factory.
The housing comprises the housing metalwork and connectors at the rear into which the boards in the cradle plug
into.

HOUSING VARIANTS

The P40 Agile range of products are implemented in one of three case sizes. Case dimensions for industrial
products usually follow modular measurement units based on rack sizes. These are: U for height and TE for width,
where:
1U = 1.75 inches = 44.45 mm
●
● 1TE = 0.2 inches = 5.08 mm
The products are available in panel-mount or standalone versions. All products are nominally 4U high. This equates
to 177.8 mm or 7 inches.
The cases are pre-finished steel with a conductive covering of aluminium and zinc. This provides good grounding
at all joints, providing a low resistance path to earth that is essential for performance in the presence of external
noise.
The case width depends on the product type and its hardware options. There are three different case widths for
the described range of products: 20TE, 30TE and 40TE. The products in the P40Agile range can be used as a K-
series refit and the cases, cradle, and pin-outs are completely inter-compatible. The case dimensions and
compatibility criteria are as follows:
