The Festo SMT-8M-A-PS-24V-E-3-M8D is a 3-wire PNP normally open proximity switch running on 24 V DC. It's a magneto-inductive sensor — the kind that detects the piston position inside a pneumatic cylinder through the barrel wall. The 3-wire PNP output means it sources a positive signal when it sees the magnet, and the normally open contact closes on detection. That M8 3-pin connector makes for a quick swap when a sensor goes down on the line.

Frequently asked questions
Where can I buy the SMT-8M-A-PS-24V-E-3-M8D?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm picture.
What does the 3-wire PNP normally open output mean?
The 3-wire PNP configuration means the sensor sources a positive voltage (typically the supply voltage) on the output wire when it detects the target. Normally open means the output is off (open circuit) when no target is present and switches on (closes to positive) when the piston magnet is detected. This is the standard sinking/sourcing arrangement for most PLC inputs.
