LLT M14 4Pin Connector<\/strong><\/p>\n

\"LLT

LLT M14 4Pin Panel<\/p><\/div>\n

LLT waterproof M14 connector (readily available from Aliexpress – search for M14 connector, check for the LLT logo)<\/p>\n

Sealing caps are available, waterproof cable plug backshell, seals at connector interfce, seals on panel connector, inline cable and panel.<\/p>\n

We use this connector for industrial sensors.<\/p>\n

The 5Core is a trailer cable, no shield, sheathed
\nSuitable for short RS485 cable lengths and small systems<\/p>\n

Otherwise use a twisted 100R pair for the RS485 A,B conductors
\nTerminate the twisted 100R pair at the ends of the cable
\nUse with an adequately rated power pair for a distributed system<\/p>\n

If using Cat5e cable, we use (wire colours by EAI\/TIA T568A)<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Cat5e patch cable (4 pairs sheathed) conductor resistance should be less than 0.188R\/m.<\/p>\n

Using POE for guidance (13W POE), we suggest using 24V or 48V for the PWR source, and limiting current to less than 350mA.<\/p>\n

A RXEF030** on both the PWR 0V and PWR +V at the power source might be a low cost solution worth considering. At 300m of cable, 300mA load, expect a round trip voltage drop of ~17V. (31V @ 300mA at the load ~10W)\u00a0We recommend the use of isolated RS845 interfaces.<\/strong><\/em><\/p>\n

** see the RXEF030 characteristics over temperature to review the maximum load current for your application<\/p>\n
