Why our pressure switches are ideally suited:
- Very fast response time
- Precise switch points in the low-pressure range
- M12x1 electrical connector with IP67
Robot lines – safety enable via pressure monitoring
In a robot line, no one may enter the enclosure as long as movement is still possible. Whether this is the case is indicated by the line pressure: only when it falls below the defined threshold, typically 200 mbar, does the control system release the access door. Our pressure switch provides the signal for this—quickly and reliably. Its response time affects both: employee safety and system availability.
Why our pressure switches are ideally suited:
- Fast, defined shutdown response
- Reliable switch points in the range < 200 mbar
- Robust design for continuous industrial duty
Frequently Asked Questions
What task does a pressure switch perform in machinery and plant engineering?
In machines and systems, pressure switches often perform simple but safety- or process-critical monitoring tasks. They detect whether a defined pressure is reached, undershot, or exceeded, and then provide an electrical switching signal to the control system. Depending on the application, this can be used, for example, to enable a process step, trigger a warning, or stop a machine. Mechanical pressure switches are particularly interesting when a robust and direct switching function is required.
Why are the switch point and hysteresis so important for the process?
Not only the actual switching point, but also the reset point influences a machine’s behavior. If the hysteresis is too small, the switch may toggle repeatedly when pressure fluctuates. If it is too large, the reset may occur later than desired for the process. That is why we always consider switch point, switching direction, and reset behavior together with the specific application, and we generally set the switch at the factory according to the customer’s specification.
How can a pressure switch be adapted to existing machines and systems?
Especially in machinery engineering, installation conditions vary widely. That is why different pressure connections, electrical interfaces, cable outlets, and housing versions are available. Switch point, switching direction and—depending on the series—reset behavior can also be adapted to the application. This often allows a pressure switch to be integrated into an existing design without having to fundamentally modify the machine.
What information do we need to select the right pressure switch?
For selection, in addition to the required switch point, operating and maximum pressure, possible pressure peaks, switching direction, and the medium are particularly relevant. In addition, temperature range, installation situation, pressure connection, electrical load, and the desired connection type must be considered. The required function within the process is also important: is only a minimum pressure to be monitored, is an enable signal required, or should a machine shut down at a specific pressure condition? The more precisely we understand the function, the more specifically we can select the right version.
