- The PSENmag for single connection have an internal resistor to limit the switching current. The service life of the contacts is increased as a result. If several PSENmag safety switches for single connection are connected in series, the resistance will increase and the evaluation device will no longer start.
- PSENmag for series connection does not have an internal resistor. The multiple interface PSEN ix1 takes care of current limitation on these switches.
