The SNH Series from Wieland Electric is a modular system that can be perfectly adapted to the needs of the machinery manufacturer, with a range of eight operator elements that can be combined with 12 different contact blocks. In addition to the modular components, Wieland supply a number of completely assembled emergency stop pushbuttons for the most common applications.
For increased safety, Wieland's SNH Series of Emergency Stop Pushbuttons incorporate a unique contact block drop-off feature offering a signal output should failure occur if the contact block becomes dislodged due to vibration. This has an additional NO contact in series (pre-installed) to the main contacts, the NO contact opening as soon as the contact block falls off, thus interrupting the safety circuit and putting the machine into a safe position. An illuminated Stop Button also provides enhanced safety for the machine user.
SNH Pushbuttons are unlocked by rotation or with the use of a key and are supplied with or without a protective collar. The pushbuttons offer a high degree of protection with an IP69 rating and the switching capability of the contacts is AC250V/16A. Wieland’s SNH Series has been designed for use in conjunction with the company’s 400 Series relays, SMA Safety Sensors and samosPRO, a compact modular safety controller for machine and automation control.
