Product details

It uses a non-contact sensing method to detect the presence of metallic targets within its detection zone, making it suitable for position sensing, end-of-travel detection, and part-presence verification on automated machinery and conveyor lines.

Frequently asked questions

When sourcing SIEF-M8NB-PS-S-L, what's the closest functional second-source — SIEN-M8NB-NS-S-L?

The SIEN-M8NB-NS-S-L is the closest peer but uses an NPN normally closed output, so it is not a direct second-source without verifying the control circuit polarity.

Will SIEF-M8NB-PS-S-L drop into a panel that was specified around SIEN-M8NB-NS-S-L without rewiring?

No, because the output type differs — PNP NO versus NPN NC — which typically requires checking the PLC input card and possibly rewiring the sensor connection.
