June 15, 2008 - TWINSBURG, OH – Pepperl+Fuchs introduces a new family of Emergency Stop (e-stop) Switches with integrated Safety at Work (SaW) functionality. These intelligent e-stop switches are powered by the AS-Interface network and offer fast, error-free installation in field or panel-mount applications.
Field and panel-mount models are available in high intensity, wide angle illuminated versions, as well as non-illuminated versions, to suit any e-stop application requirement.The field-mountable versions eliminate all wiring to save time and eliminate the possibility of incorrectly wiring the e-stop switch, and feature an M12 connector that works in conjunction with Pepperl+Fuchs’ popular flat-to-round cable adapters to reduce installation time to less than 60 seconds.Panel-mount versions include connection cable that is quickly cut to length, and easily connects to the AS-Interface network using Pepperl+Fuchs’ flat cable-to-terminal adapter, or the terminals of other nearby enclosure-mount modules.
Additionally, the AS-Interface node is an integral part of the panel-mount e-stop switch so only the e-stop itself needs to be mounted. “Illuminated models are lit with a high intensity LED to eliminate the need for auxiliary power, while reducing the number of required leads to two. By reducing the number of leads it may be possible for users to operate their AS-Interface system solely on the networks popular flat yellow cable,” says Helge Hornis, PhD, Intelligent Systems Manager for Pepperl+Fuchs. “For added flexibility, the LED is not activated by the button but is controlled by a PLC, which allows users to solve even the most unusual applications,” he says. Non-illuminated e-stops provide safe operation at a lower price point than illuminated models.
“Most safety buttons use either a twist or a pull release, and both are effective so long they meet the users preferred mode of operation. Pepperl+Fuchs’ new family of Safety at Work e-stop switches support both methods so whatever the preference, operators will feel right at home,” says Dr. Hornis.Pepperl+Fuchs is a world leader in the design, manufacture and application of high quality factory and process automation products and services. Pepperl+Fuchs pioneered the development of proximity sensors 45 years ago, and has set the standard for innovation and quality ever since.
