SMC D-M9 Series Switch, 24V Voltage, 4mm Width - D-M9PZ

This switch is a compact solid-state sensor designed for direct mounting on pneumatic cylinders to detect position and provide a 3‑wire PNP output for control circuits. It operates from a low DC supply and includes an integral LED for visual status, making it suitable for inline installation where a slim profile and electrical switching for PLCs or relays are required.

Features and Benefits:

• 3‑wire PNP output supports straightforward PLC/relay interfacing
  Operating voltage range 4.5-28V DC delivers flexible supply options
  Switching current up to 40mA enables direct drive of sensing inputs
  Leakage current ≤100μA minimises false signals during idle states
  Internal voltage drop ≤0.8V at 10mA reduces signal loss
  Compact 4mm width provides space‑saving installation

Applications

• Suitable for direct-mount SMC cylinder position sensing
  Ideal for integration with PLC and relay control loops
  Used with IC circuit inputs requiring low-current switching
  Can be used for inline proximity detection in tight spaces
  Suitable for automation needing visual LED indication

What wiring arrangement does it require for installation?

It uses a 3‑wire configuration with a PNP output that switches the load to the positive rail.

How long is the standard lead available for remote mounting?

A lead option is provided with a 5m length to accommodate distance between sensor and control equipment.

What is the device’s behaviour at maximum switching current?

At 40 mA the internal voltage drop can be up to 2V, which should be considered for input threshold margins.

How does the unit perform across temperature extremes?

It operates reliably from -10°C up to 60°C, suitable for typical industrial environments.
