By distributing the electrical signal to be transmitted to as many contact points as possible, they guarantee high contact reliability.
Using the welding process developed by Heraeus, multiple wires can be joined directly with the carrier material to form these so-called multi-wire wipers. Unlike the wipers manufactured by means of stamping technology, the multi-wire wiper is made by welding up to 40 wires parallel to each other onto a support material. This significantly increases the number of contact points of each contact area.
The large number of individual wires of spring-hardened contact materials and their adaptation to variable contact tracks provides an optimal electrical contact. By using corrosion resistant contact materials, multi-wire wipers are also suitable for application in corrosive media, e.g. in fuels.
The large selection of standard designs (open tool designs), which are available without any additional tooling charge, is a particular advantage for you. However, it is also possible to design the multi-wire wiper individually according to your requirements.
In addition to individual multi-wire wipers, we are also able to offer you complete modules as well as heat-stacked, overmoulded, or joined multi-wire wipers.
We would be happy to advise you.
