Schlegel emergency-stop active/inactive is award-worthy

The active/inactive principle of the emergency-stop SIL_QRBDUVOOM125 is based on the standard EN ISO 13850:2015 which allows to also indicate the operating statuts of emergency-stops by a corresponding illumination. In order to avoid any confusion of active/inactive emergency-stops and thus to increase the work safety, Schlegel has developed emergency-stops which signal the active and inactive status according to this principle. The mushroom of the new active/inactive emergency-stops is no longer coloured in red, instead it is made in a semi-transparent shade of grey. The transparency allows to illuminate the mushroom in red in case it is in an active status and thus it can clearly be identified as functioning emergency-stop. If the emergency-stop is inactive, the mushroom is not illuminated and grey. An inadvertent actuation of an apparently active emergency-stop in case of an emergency is thus being avoided as it will not be identified as emergency-stop. Thus, it is no longer necessary to lock away or cover an inactive emergency-stop. The range of emergency-stops of Georg Schlegel GmbH & Co. KG comprises a large number of types which are different in size and shape and which are designed for different fields of application. Mounting apertures of Ø 16.2 mm, Ø 22.3 mm and Ø 30.5 mm as well as 23 x 23 mm, 24 x 24 mm and 26 x 26 mm are possible, the degree of protection ranges from IP65 to IP69K, and there are variants with protective shroud or anti-lock collar, key release and emergency-stops for hygienic applications. Nearly all emergency-stops can be realised with release by turning (in either direction) or by pulling. Furthermore the construction of the emergency-stop devices allows the reliable function for voltages up to 440 V and for low voltages which are being required more and more. This is ensured by the self-cleaning function of the contacts and by the springs being dimensioned for a good contact pressure. Customer can either choose silver or gold-plated contacts. All contact blocks are available for screw connection, with Faston terminals, with Cage-Clamp or push-in connection. They have positive opening contacts acc. to EN 60947-5-1 and there are solutions for one or two channels. Depending on the version a maximum of 4 NC contacts per emergency-stop is possible.
