Signal connectors for precise connections in industrial electronics

Signal connectors are fundamental components of modern electronic systems. They ensure the safe and reliable transmission of electrical signals between PCBs, assemblies or devices. Whether in smartphones, laptops, medical devices or industrial measuring systems: signal connectors are used wherever compact, robust and precise contact solutions are required.

As an experienced distributor in the field of electronic connection technology, Rotima AG offers a specialized range of signal connectors in cooperation with the renowned manufacturer Bourns. These high-precision components impress with extremely small pitch distances of up to 0.25 mm, gold-plated contact surfaces for optimum conductivity and a long service life with repeated mating. Thanks to automated processing with pick-and-place technology, they are ideal for demanding series production.

Technical structure of signal connectors for electronic applications

Signal connectors consist of precision-manufactured plastic housings with integrated metal contacts that are electrically conductive and mechanically stable. Variants with a narrow pitch of just 0.25 mm are used in the electronics industry in particular to ensure a high packing density even in space-critical designs.

The contact surfaces are usually gold-plated to ensure low contact resistance, high current carrying capacity and a long service life with frequent mating cycles. Thanks to their modular design, these connectors can be easily integrated into automated production processes, for example using pick-and-place methods. This ensures reliable signal transmission even under demanding conditions.

Signal connectors for compact devices and industrial electronics solutions

Signal connectors are used wherever compact, reliable and durable connections are required. In consumer electronics, for example, they are used in smartphones, DECT telephones and laptops to connect circuit boards, displays and batteries in a space-saving manner. They are also an essential component for signal transmission in rechargeable battery units and portable measuring devices.

In medical technology, signal connectors ensure secure data and power connections in portable diagnostic systems or analysis devices. Due to their small design and the possibility of fully automatic assembly using pick-and-place technology, they are also ideal for industrial series production.

In industrial applications, they are used in control and test systems where reliable contact quality and long mating cycles are crucial. The gold-plated contacts, high current carrying capacity and RoHS conformity make them a reliable solution for a wide range of electronic applications with high quality requirements.
