Frequently Asked Questions
What is the SMT-8M-A-PS-24V-E-0 sensor?
It is listed as a magnetic proximity sensor for compatible Festo pneumatic cylinders. The reference SMT-8M-A-PS design is a T-slot magneto-resistive sensor with PNP normally open switching.
Is this product manufactured by Festo?
The listing identifies the item as a sensor for Festo. This wording does not independently establish that the supplied product is manufactured by Festo. Confirm the actual manufacturer and product label before ordering.
What is the nominal operating voltage?
The corresponding Festo SMT-8M-A-PS reference design is rated for 24 VDC and has a documented operating range of 5 to 30 VDC. Verify the supplied sensor rating.
Is the switching output PNP or NPN?
The PS code in the Festo reference designation identifies a PNP switching output.
Is the output normally open or normally closed?
The PS configuration indicates a normally open output. Confirm that the supplied sensor matches this switching arrangement.
What does this sensor detect?
The sensor is intended to detect the position of a magnetic piston inside a compatible pneumatic cylinder.
What type of mounting slot is required?
The reference SMT-8M-A sensor is designed for a compatible pneumatic cylinder T-slot and can be inserted from above.
What is the maximum output current?
The Festo SMT-8M-A-PS reference series specifies a maximum output current of 100 mA. Do not apply this limit to an unverified replacement without checking its documentation.
Does the model include an M8 connector?
An industrial distributor associates the shortened reference SMT-8M-A-PS-24V-E-0 with Festo part number 574334, whose full designation ends in 0,3-M8D. However, the supplied abbreviated model alone does not confirm the connector. Verify the complete product marking.
What cable length does the sensor have?
The Festo 574334 reference uses a 0.3 m cable. Other models in the same family have different cable lengths, so the supplied configuration must be confirmed.
Can the sensor replace an existing Festo cylinder sensor?
Compatibility should not be assumed solely from the model prefix. Compare the complete reference number, T-slot fit, electrical output, voltage, cable length, connector and operating environment.
What should be checked before ordering?
Confirm the model SMT-8M-A-PS-24V-E-0, actual product manufacturer, complete model suffix, PNP normally open output, supply voltage, mounting slot, maximum load current, connector type, cable length and the specifications of the original sensor being replaced.
