The SMT-8M-A-PS-24V-E-0,3-M8D Proximity Sensor: SMT-8M-A-PS-24V-E-0,3-M8D drops into the T-slot of Festo DSNU, DNC, and most standard profile cylinders. It's a common retrofit part when the original sensor fails on a pick-and-place or clamping station.
Because the lifecycle stage is current, you can expect normal factory lead times through the Festo distribution channel. No need to stockpile or chase surplus.
