Construction type
Solid shaft (flange), Hollow shaft
Output signals / Interfaces
Switch output speed
- Monitors overspeed and standstill
- Hollow shafts (isolated ball bearings) up to Ø 17 mm, solid shaft Ø 11 mm (flange mounting)
- Nonwearing semi-conductor switch (NO contact): one switching output set ex works
- Switching capacity up to 30 VDC and 0.5 A
The preset speed monitors
The electronic speed switches monitor the factory-set speed with high switching accuracy, including low operating speeds. Alternatively, they can be used as standstill monitors. As a consequence, the speed switches play their part in system and personnel protection. They are installed on motors, for example in cranes, in mining operations as well as in rolling mills and more.
