Cable limitations on LSP Head performance

The LSP Head is a fast response precision instrument. However, some cable

configurations may limit the practical (useable) scanning speed and the dynamic

performance of the LSP Head, through cable capacitance and external noise.
The following tables show the recommended cables when considering cable

length and scan frequency.

Notes

LSP 15m cable can be standard 031-402 or high temperature 031-794

LSP type cable is 12 core 16/0.2mm DEF STAN 61.12pts 4 & 5

Terminal box 802869 is a passive connector allowing connection of different

cable types

Terminal box with PSU 802662 includes a local LSP head power supply. This

is used where the head to processor cable distance exceeds 15m when using

an LSC-C processor, and 165m when using an LSC-B processor

Belden cable 8162/8163 is used for the Scan Valid and Fast temperature

signals from the LSP head

Belden cable 8177 may be used for additional signals such as Emissivity,

IATS and remote laser switch
