Is Difficult To Determine All The Applications For These Circular Shell
Threaded Coupling Connectors. They Are Available For Many Applications
From Commercial / Industrial Use To The Most Stringent, High Reliability
Military And Space Applications. Since They Provide For Minimum Effort
In Usage, They Are High Economy Upgrades For Existing Applications And
Provide Simplified Design For New And Interphase Equipment. Refer TDS-Connector
Features For More
Details. What
Does Plug & Receptacle Mean? These
Are Conceptually Plugs & Sockets Used By Us In Daily Life. These Are
Used For Heavy Duty Applications. Plug Means The Part Which Bears The
Coupling Nut And Which Is Free When Unmated. Receptacle Is The Mating
Component Which Is Normally Fixed To The Equipment Except For The Cable
Connector Where Both Mating Parts Are Free. Why
Are Contacts Referred To As Plug & Socket Pins? The
Contacts Are Generally Mated Together On The Fasting Of The Plug &
Receptacle Of The Connector. The Mating Is In The Form Of Plug (Male)
& Socket (Female) Contact Pins. Therefore, The Contact Are Referred
To As Plug & Socket Pins. How
Do I Select The Appropriate Connector For My Application? What
Information Is Required For Selection Of Connectors? Refer
TDS Selection Guide
Which Offers A Detailed Explanation And Guidance On Choosing The
Appropriate Connector For Your Application. It Also Details The
Information Required Prior To The Selection For Short Listing The
Connector Suited To Your Application. What
If I Cannot Find A Connector Suited To My Application As Per My
Requirements? If
A Connector Suited To Your Application Does Not Already Exist, Please
Write To Us With The Information Regarding The Number Of Wires To Be
Used In The Application Alongwith The Operating Voltage Required,
Current Carrying Capacity Required For Each Wire And The Mounting
Requirements And We Can Develop A Customized Connector Suited To Your
Application. Refer TDS
Selection Guide For
More Details. What
Is The Standard Scope Of Supply For Circular Shell Threaded Coupling
Connectors? The
Standard Scope Of Supply For The Circular Shell Threaded Coupling
Connectors Plug And/Or Receptacle Include Cadmium Plated Premium Grade
Aluminium Alloy Shell With Olive Green Passivation, Silver Plated
Machined Copper Alloy Contacts With Solder Termination, Grey
Colored Polychloroprene Insert Insulation With Strain Relief Cable
Clamps. Other
Options And Accessories Are Available On Request. Refer TDS
Ordering Instructions
For More Details. What
Are The Shell Size Implications? How Should I Choose The Shell Size? The
Shell Size Is Usually Determined By The Available/Allocated Mounting
Space For Receptacles On The Equipment. Since The Cost Increases With
The Increase In Shell Size, Where Multiple Insert Arrangements Are
Available For Your Requirement It Is Usually More Economical To Start
With The Lower Shell Size And Progressive Go To The Higher Shell Size.
At Times It Is More Economical To Add An Extra Contact In Your
Requirement Than Go For A Higher Shell Size With The Same Number Of
Contacts. What
Is Normal And Reverse Assembly? How Should I Choose The Correct Assembly
For My Application? Normal
Assembly For Circular Shell Threaded Coupling Connectors indicates that
Plug Pins are used in the Straight Plug Insert and Socket Pins are used
in the Wall Mounting / Cable Connecting / Panel Mounting Receptacles
Inserts. Reverse
Assembly For Circular Shell Threaded Coupling Connectors indicates that
Socket Pins are used in the Straight Plug Insert and Plug Pins are used
in the Wall Mounting / Cable Connecting / Panel Mounting Receptacles
Inserts. As
a general safety practice, the live component side, that is, the
component side which provides the current input to the equipment should
have the Socket Pins in the Insert. Therefore, if the Straight Plug is
live then it should have Socket Pins in the Insert and hence Reverse
Assembly and if the Wall Mounting / Cable Connecting / Panel Mounting
Receptacle is live then it should have socket pins in the insert and
hence Normal Assembly. Does
The Insert Arrangement Number Indicate The Shell Size And The Number Of
Contacts? No.
This is just a number which has been allocated by the Military
Specifications. Therefore, the number after the shell size in the insert
arrangement number does not specify the number of contacts. For Example,
36 10 Insert Arrangement Number signifies the Insert as 36 Shell 48
Pin Insert. How
Can I Order Special Requirements For My Application? Refer

those on the Ordering instructions page, use the response form to get in
touch with us for more details. When
Should I Use Nickel Or Gold Plated Contacts Instead Of Silver Plated
Contacts? Silver
plated contacts serve most general purpose applications. However, where
there is a requirement where very high Potential Drop values are
permitted, Nickel Plated Contacts can be used in place of Silver Plated
Contacts. This allows for a marginal decrease in the overall cost also.
Similarly, where there is a requirement where very low Potential Drop
values are permitted, it is adviseable to use Gold Plated Contacts in
place of Silver Plated Contacts. These would cost marginally more also. When
Should I Use Normal And/Or Reverse Assembly? As
a general safety practice, the live component side, that is, the
component side which provides the current input to the equipment should
have the Socket Pins in the Insert. Therefore, if the Straight Plug is
live then it should have Socket Pins in the Insert and hence Reverse
Assembly and if the Wall Mounting / Cable Connecting / Panel Mounting
Receptacle is live then it should have socket pins in the insert and
hence Normal Assembly. Also,
when similar sets of connectors are being used very close together,
using a combination of both normal and reverse assembly eliminates the
chances of accidental cross mating of the connectors which could have
disastrous results. When
Should I Use Silicon Insert Insulation Instead Of Polychloroprene
Insulation Insert? Polychloroprene
Insert Insulation generally suffices for most applications. However,
Silicon Insulation Inserts are recommended and used where the connectors
are directly exposed to very high temperatures in excess of 120 degrees
Centigrade. When
Should I Use Crimp Contacts Instead Of Solder Contacts? Solder
Contacts generally suffice for most applications. However, Crimp
Contacts are recommended and used where the connectors are directly
exposed to high vibration thereby avoiding loose contacts and dry
soldering is avoided. Where
Can I Find The Dimensions For The Plug & Receptacles? Refer
TDS MS 3100 / TDS
MS 3101 / TDS MS
3102 / TDS
MS 3106 for
detailed dimensions for the Plug & Receptacles. If
I Am An Existing User Of MS Connectors, How Do I Select SLPL Connectors? Locate
the Code of the MS Connectors marked on the Connectors (If not already
available with you). Simply replace the MS 3100 / MS 3101 / MS 3102 / MS
3106 with SE 00 / SE 01 / SE 02 / SE 06 respectively and
this would give you the SLPL Code for these connectors. It is possible
that the arrangement is not available with us, in which case we can
develop the same. If the coding does not follow the MS pattern, please
send the code that is available on the connector and we shall provide
the alternate compatible MS / SLPL Ordering Code. If
I Already Have A Plug Or Receptacle, Can I Purchase The Mating
Connector? YES, you can purchase a Plug and / or a Receptacle separately. Since these are manufactured in accordance with JSS 50812 (Indian Military Specifications) & MIL C 5015 (American Military Specifications), they are fully interchangeable with the corresponding mating part available with you and manufactured as per the above specifications.
