Choosing the Right Terminals and Connectors
Every conductor in a panel or machine ends at a terminal or connector. Choosing between screw and spring clamp DIN rail terminals, and between fixed wiring and pluggable connectors, affects build time, maintainability and how quickly a machine can be installed on site.
DIN Rail Terminals
Screw, spring-clamp and push-in terminal blocks land field wiring and distribute control and power circuits inside the panel.
- Field wiring
- Control circuits
- Power distribution
- Earth terminals
- Fuse terminals
Multi-pole Connectors
Heavy-duty rectangular connectors plug power, control and data between machine sections so equipment can be shipped and installed in modules.
- Machine modules
- Motor connections
- Control cabling
- Test equipment
- Robot cells
Industrial Plugs & Sockets
IEC 60309 plugs, sockets and appliance inlets connect portable and fixed equipment to power safely from 16 A to 125 A.
- Portable equipment
- Machine power
- Site distribution
- Events & temporary
- Marinas & leisure

View All ManufacturersFrequently Asked Questions
Common questions about terminals and connectors. Our technical team can help with ratings, accessories and cross-references.
Screw, spring-clamp or push-in terminals – which should I choose?
Screw terminals are familiar and accept a wide conductor range. Spring-clamp and push-in DIN rail terminals are faster to wire, vibration-proof and need no re-torquing, which is why most new panels use them. Many panel builders standardise on one technology to keep tooling and accessories simple.
How do I choose a multi-pole connector?
Count the power and control contacts needed, check the current and voltage per contact, then select the insert and a housing size and IP rating to suit. Multi-pole connectors can mix power, signal and pneumatic modules in one frame.
What do the colours on industrial plugs mean?
IEC 60309 plugs and sockets are colour-coded by voltage: yellow 110 V, blue 230 V, red 400 V, with the earth pin position also indicating the voltage so mismatched plugs cannot connect.
Do I need end plates and jumpers?
Yes. Open-sided terminal blocks need an end plate on the last terminal of each group, and jumpers are used to common terminals for distribution. Both are in terminal accessories along with markers and end brackets.
Can I terminate fine-stranded flexible conductors directly?
In push-in terminals fine-stranded conductors should be fitted with a ferrule; spring-clamp and screw terminals accept them directly. Check the terminal datasheet for the accepted conductor types.
Which terminal and connector brands does LED Controls supply?
We supply ILME, IMO, Emas, ABB, Cembre, Lovato Electric and Gewiss.
Do you offer trade accounts?
Yes. Trade accounts are available for panel builders, machine builders, contractors and industrial customers.
