Omron D41L Series Solenoid Interlock Switch, Power to Unlock

Omron D41L Series Solenoid Interlock Switch, 24V DC Supply Voltage, IP66, IP67, IP69 - D41L-2ZDA-N2

This solenoid interlock switch is a coded guard lock device designed to secure access to machinery while reducing tampering risk in hygiene-sensitive environments. It operates as a power-to-unlock safety switch using a 24V DC supply and provides monitored safety outputs for guard and lock status. The unit features a smooth thermoplastic housing for easy cleaning and high ingress protection, making it suitable where water and dust resistance is required. The actuator is supplied separately.

Features and Benefits:

• 24VDC supply with 0.1A contact rating ensures low-power operation
  IP66 IP67 IP69 protection for washdown and dusty environments
  M12 connector simplifies connection and reduces wiring errors
  Power-to-unlock mode enables safe manual access during de-energised state
  Single auxiliary contact provides status signalling to PLCs
  High tolerance to misalignment maintains reliable latching performance

Applications

• Suitable for hygiene-sensitive food machinery guarding
  Used with safety controllers for PL e interlock circuits
  Ideal for washdown environments requiring IP69 protection
  Used for monitored door locking with external diagnostics
  Suitable for Compact machine enclosures with limited space

What connection type does it use for wiring?

It uses an M12 8-pole connector for main and auxiliary wiring.

How does the locking behaviour operate electrically?

The solenoid is energised at 24V DC to release the lock in power-to-unlock configuration.

What diagnostic or status outputs are available?

It provides dual safety outputs (OSSD) and one auxiliary PNP output for status or PLC input.

How is actuator pairing and tamper protection handled?

The switch employs high-coded RFID pairing with individual coding options to limit unauthorised actuator replacement.

What mechanical holding and operating limits apply?

The device delivers selectable latching force and is rated for specified holding and operating forces with defined misalignment tolerances.
