------Question for CM-S1PC3 Please Put your question below------
Greetings, I was looking at adding a simple interlock to a probing system where we are adding a laser. I’m looking at CM-S1PC3. Is there a simpler magnetic interlock system available?
Thanks,
-Mike
A version of that type of item that would be more simple would be the 3667-PSA60010-ND(switch) + 3667-P6250000-ND (magnet for the switch). The 3667-PSA60010-ND would be just a SPST-NO item vs the DPST-NO/NC that original was.

If this would not work. You would need to elaborate on what you are needing.
Hi again, we ordered some PSA60010 interlocks. Unfortunately, when the magnet is brought close to the switch, the resistance only drops to ~280 ohms, and the manual says the interlock circuit should be a short, and we think ~280ohms will probably be way too high to allow our laser to function. We do have two older magnetic interlock switches, and when the magnet is brought close to those switches, the resistance drops to ~0.2ohms, which is what we expected. Can you recommend another switch which would function more like that? Thanks!
Hello Again Micheal.
I am sorry to inform you that there is no filter for resistance.
The customer will have to see if it is listed in the datasheets.
These are a list of similar switches.
The PSA60010 datasheet indicates that the device is thyristor-based. As such it is adapted for switching AC currents, and cannot be expected to work with a DC source or return a reasonable result when measured as a resistance with a multimeter.
