Silver contact - Import export

These high-power bimetal operated temperature switches are available either with normally closed (NC) or normally open (NO) contact configuration. The robust round metal enclosure accommodates a resilient preloading disk, a bimetal disk and a silver contact. The compact switch system is covered by means of a plate which also carries a silver contact and is isolated from the enclosure by means of an isolating washer. The resilient preloading disk ensures excellent performance. The resilient preloading disk keeps the contact pressure constant throughout the entire temperature range of the BEDIA switch until switching occurs. The mechanically and electrically unloaded bimetal disk snaps over at a preset temperature, with either opening or closing the contact arrangement. The bimetal will only snap back to its initial condition after the temperature has dropped significantly.

The simple and compact design of this miniature PE converter with fixed switch-on pressure of 0.8 bar allows its use in various applications such as medical technology, dental treatment units, robotics, analysis systems, process and safety engineering. Easy mounting and high functional reliability are other advantages. By using silver contacts a long lifetime can be ensured even at high switching frequencies. As a result of the fire-risk evaluation according to EN 13463-1, the pneumatic timers are not subject to ATEX regulations. This means they may also be used in explosion hazardous areas as defined in IIG/ IID.

Housing, die-cast zinc. Housing cover, plastic, self-extinguishing. Hinge bolts, die-cast zinc/steel C45. Contacts, silver-nickel alloy 10. Note: The security hinge switches are used for monitoring the position of swing-hinged safety doors, protective hatches and hoods. The protective device is monitored directly in the hinge. By the universally pre-set versions, the switching angle is freely adjustable over the entire working range. A mounting aid ensures the quick alignment to doors and posts. The additional hinges have the same appearance and dimensions as the security hinge switches. The loading values given for the hinges are non-binding reference values without consideration of safety factors and exclude any liability. The values given are for information purposes only and do not constitute a legally binding assurance of properties.
