This catalogue of coilformers contains information on all our products of the RM - Series (Rectangular Module Cores)
The components of the RM-Series, standard or low-profile, are of compact and almost closed design. They are especially suitable for pulse transformers, storage chokes, filter application, dc-converters etc.
We supply coilformers in high quality thermoplastics, exactly to meet your production requirements and product specification.
All dimensions in mm/inch. The permissible deviations according to DIN 16901 apply as tolerances.
Wherever high-temperature soldering processes are used in connection with RM-Series coilformers, we recommend irradiation cross-linked plastics. This ensures that the mechanical properties - in particular those or gfr-polyamides - are maintained and breakages are reduced. For this reason NORWE offers all plastic components of the RM-Series in irradiated cross-linked materials.
In the short term, the cross-linked materials can be exposed to very high temperatures. Apart from improved aspects in production there may be interesting cost advantages, and a discussion with us could be useful.
Should you need further assistance, be it technical or to assist when placing your order, we look forward to hearing from you.
Fully tagged or pinned coilformers are - in small quantities - usually available from stock. We can also quote for coilformers with pins or tags fitted to your requirements. All lead-times are relatively short.
Our extensive range of modular tooling allows almost unlimited constructional changes to customers specification, often by simple changes of tool inserts. In addition, our modular tooling system allows short tooling times and can be very cost effective.
Standard RM, RM-LP Low Profile with Dual-in-Line solder-pins
The coilformers are made in gfr Polyethylene Terephthalate PET of type rtg nat. (RTI long-range temperature +155°C) and made in gfr Polyamide PA66 of type p6g (RTI long-range temperature +125°C). Pin material: tin bronze, tinned. Maximum solder temperature 350°C, 2 sec. Special materials - eg. irradiated cross-linked - and designs on request, dimensions in mm/inch. |
 |
Two types of Dual-in-Line solder-pins can be fitted. L-shaped type h for radial binding on, side wrapping and soldering. Tension relief for thin or litz wire is possible. Straight solder-pins type z for axial binding-on and soldering. Less pcb area is required using this solder-pin.

Standard RM with Dual-in-Line solder-tags
The coilformers are made in gfr Polyethylene Terephthalate PET of type rtg nat. (RTI long-range temperature +155°C), Polyamide PA66 of type p6g (RTI long-range temperature +125°C) and A3X2G10 (RTI long-range temperature +115°C). Tag material: brass, tinned. Maximum solder temperature 350°C, 2 sec. Special materials - eg. irradiated cross-linked - and designs on request, dimensions in mm/inch. |
 |
The coilformers have two rows of solder-tags, pcb-style dual-in-line. Binding-on of thin wire and litz can be done radially, and tension relief is possible. A tolerance-compensator (TA) on the top flange eliminates the normally used spring-washer.
RM 6 - RM 14

Standard RM 45° with Dual-in-Line solder-tags
The coilformers are made in gfr Polybutylene Terephthalate PBT of type pcg (RTI long-range temperature +130°C). Tag material: brass, tinned. Maximum solder temperature 350°C, 2 sec. Special materials - eg. irradiated cross-linked - and designs on request, dimensions in mm/inch. |
 |
The coilformers have up to 3 solder-tags dual-in-line. Binding-on can be done radially. Tension relief for thin wire or litz is achieved by bending the tag-sides towards the winding section. A tolerance-compensator (TA) on the top flange eliminates the normally used spring-washer.

RM Power Conversion 45°
The coilformers are made in gfr Polyphenylene Sulfide PPS of type torA504 (RTI long-range temperature +130°C). Pin material: tin bronze, tinned. Maximum solder temperature 300°C, 2 sec. Special materials - eg. irradiated cross-linked - and designs on request, dimensions in mm/inch. |
 |
The coilformers are fitted with straight solder-pins. Binding-on of the wires is axially. The wires are guided into the winding room through centrally positioned slots in the lower flange. A reinforced flange reduces the risk of breakage when binding-on the wire and ensures a tight fit of the solder-pins which are inserted after moulding.

RM Power Conversion 45°, Specials
The coilformers are made in gfr Polyamide PA66 of type p6g (RTI long-range temperature +125°C). Pin material: tin bronze, tinned. Maximum solder temperature 350°C, 2 sec. Special materials - eg. irradiated cross-linked - and designs on request, dimensions in mm/inch. |
 |
The pin layout on the lower flange of these specially designed coilformers allows simultaneous binding-on and winding of two wires (bi-filar). Compared with standard RM-coilformers, 12-32 solder-pins are available. In addition, winding and soldering can be done fully automatic.
