FAQ

Question? What does the ‘Z’ in the type designation MSD-A-Z signify?

The ‘Z’ in Festo’s naming convention for this product indicates that it includes a Z-diode (suppressor diode) for circuit protection. This helps to suppress voltage spikes that can occur when the solenoid coil is de-energized.

Question? Is this connector suitable for both AC and DC applications?

No, this specific model, 164274, is designed exclusively for 24V DC operation. This is indicated by the “24=” marking and the integrated polarity-sensitive LED and protection diode. Using it with AC voltage or incorrect DC polarity will damage the internal circuit.

Question? What is the recommended tightening torque for the central mounting screw?

According to the Festo datasheet, the recommended tightening torque for the M3 central screw is 0.4 Nm. Overtightening can damage the connector or the valve’s coil housing, while under-tightening can compromise the IP65 seal.
