Non-contact magnetic safety switches PSENmag

Why are only some PSENmag suitable for series connection and how do they differ from the PSENmag for single connection?

  • 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.
