Industrial circular connectors are safe to use and contamination-proof

Binder now offers its 709 and 719 series products with a new overmoulding for the straight versions. High retention forces characterise the connectors featuring snap-in locking – measured against their size – but can still be quickly mated and unmated. These properties, for example, are advantageous in metrology and medical device technology applications, which are subject to enhanced functional safety requirements.

In instrumentation and medical technology, it is often important to protect devices and their interfaces against environmental contamination, so the company's engineers have developed a triangular overmoulding design that features no gaps, grooves, or undercuts allowing dirt to accumulate. This greatly increases the applications' resistance to contamination. Furthermore, the straight product variants are very easy to handle thanks to the new type of overmoulding, making one-handed mating and unmating safe and comfortable.

When developing the new overmoulding, the company's product designers succeeded in maintaining the properties at the same high level as the previous version despite the new design not having special kink protection. The kink protection ensures the strands do not break under mechanical stress when the cable kinks. This was proven in advance by means of bending tests.

The 709 and 719 snap-in series offer users the benefits of a fast and secure locking system with high retention forces. The products are available as male and female cable connectors with or without strain relief. The three to five-pole series has been designed for wire gauges up to 0.25mm2 (up to AWG 24) and soldering or dip soldering termination. The IP40-protected products achieve a mechanical lifespan of 100 or more mating cycles.
