RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |

Applications
These insulated crimp ring wire connectors are used in a wide range of industries for connecting wires to electrical components. The design of this wire connector means that is ideal for use in high vibration or heavy industrial applications. Applications include wiring in industrial control systems and industrial machines, automotive applications, communication equipment, power supplies and domestic appliances.
Selecting the Correct Ring Terminal Size
When selecting the right ring terminal for your application, you should consider the following:
• The wire gauge mm (metric) or AWG (American Wire Gauge) of the wire or cable you are using
• The stud size to which you will be connecting the ring terminal.
• The inner diameter of the ring terminal
How to Crimp a Ring Terminal
Firstly, select the correct sized ring terminal. Strip the end of the wire and cut it to the same length as terminal. Insert the wire into the terminal barrel making sure no bare wire is visible. The crimp terminal is then ready to be crimped on to the end of the wire. When crimping a wire terminal, pliers or a ratchet can be used but, for a better quality crimp, it is better to use a ratchet crimping tool. A ratchet crimping tool is preferable as the handles will remain locked until a full crimp cycle is completed which will prevent partial crimps. Insert the barrel of the ring terminal into the appropriate crimping section (indicated by sizes marked on the tool). Squeeze the tool handles together until the ratchet releases. The crimped ring terminal can now be placed over the stud or post and secured in place with a nut or by soldering.
