LMS5xx: How to convert corroded connectors into stainless steel connectors

Challenging environment (e.g. in ports with salt and sand in the air) might lead to corrosion of the connectors of LMS5xx.
The standard version of LMS5xx is manufactured with connector material brass, nickel coated.
In case a device should be dismounted, it can become difficult to open the connection or the device might even get damaged.
This article describes how an existing installation with corroded connectors can be converted into an installation with stainless steel (inox) connectors.
Example for corroded connectors:

Please keep in mind:
Exchanging only the sensor's connectors to stainless steel is not the complete solution.
The connectors at the cables also need to be exchanged into stainless steel material. Otherwise the high-quality stainless steel material of the sensor's connectors might lead to faster corrosion of the old cable's connectors (brass, nickel coated).
 

Where existing installations of LMS5xx with corroded connectors should be modified into stainless steel connections, we recommend to:

• Exchange the sensor's old system connector into stainless steel connector Heavy Duty (vertical: 2096978, rear: 2120914, LMS531 vertical: 2128740).

• Cut the old connectors of the system's cables (only power, data, I/O)
  Ethernet: exchange connector into stainless steel connector (2109773), or put new outdoor cable in place

• Install new connection box LMS511 Heavy Duty (2095789) or LMS531 PRO (2079824)
  This connection box is equipped with stainless steel connectors at the cables.

• Connect the open ends of the old system's cables in the new connection box.

Then all "normal quality" connectors are exchanged against "high quality" stainless steel connectors.

 

The system connector with stainless steel connectors (Heavy Duty), 2096978, is mechanically and electronically compatible with the LMS511 PRO.
It is not compatible with LMS511 Lite, because the Heavy Duty version is only available with 12-pin connectors and Lite version is equipped with the 8-pin connectors.
The system connector of LMS531 PRO was delivered with material brass nickel plated until March 2022. From April 2022 on the system connector of LMS531 PRO is delivered with material stainless steel.
 

The system connector for Heavy Duty devices, 2096978, contains a cloning module.
After power-on of the device with the Heavy Duty system connector, the parameters of the new system connector will be written into the sensor. The parameters of the old sensor will be lost (overwritten).
It is recommended to save the old parameters before the exchange of the old connector.
In any case set and check the correct parametrization after changing the connector.
 

By breaking the seal labelled "QC passed" the warranty of the
device will be void.
If your device is still within the warranty period, then balance between the options to exchange the system connector on your own or send the device for repair to SICK. After the warranty period has ended, the seal can be broken without hesitation.

Remark: Heavy Duty devices (which have already stainless steel connectors) are not labelled with "QC passed", but with "Remove for cloning".

For new installation in challenging environment it is recommended to use the LMS511 Heavy Duty or LMS531 PRO device types together with the set of outdoor cables:
LMS511-12100       (1071590) Standard resolution
LMS511-12100S08 (1107124) Standard resolution with membrane

LMS511-15100       (1128608) Standard resolution Extended Range with membrane
LMS511-22100       (1071996) High resolution
LMS511-22100S08 (1107125) High resolution with membrane
LMS531-10100       (1067356) Security PRO version with membrane

LMS531-15100       (1128609) Security PRO version Extended Range with membrane
