Omron D4SL Solenoid Interlock Switch, Key, Plastic, Solenoid Lock

Omron D4SL Series Solenoid Interlock Switch, 155mm Length, IP67 - D4SL-N4RDA-DN

This solenoid interlock switch is a key-operated safety device designed to secure access points in automated and electrical systems. It combines an electrically controlled locking mechanism with safety contacts to prevent hazardous operation while panels or guards are open. The unit is built for use where a compact, sealed interlock is required and operates across a defined industrial temperature range.

Features & Benefits

• Three safety contacts provide monitored guard condition and isolation
  Solenoid lock with key operation allows controlled access remotely
  IP67 sealing enables use in wet or dust-prone environments
  Accepts M20 conduit for straightforward cable entry and protection
  Voltage capability includes 125VDC for DC-control circuits
  Plastic housing reduces corrosion risk in non-hazardous areas

Applications

• Suitable for interlocking machine guards in automated production lines
  Ideal for safety access control on electrical enclosures
  used with DC control systems requiring key-retained locking
  Can be used for Compact installations needing sealed enclosures
  Suitable for retrofit replacements where three NC safety contacts required

What contact configuration does it provide for safety monitoring?

It includes three normally closed contacts dedicated to safety circuits to enable monitored guard status and integration with interlock logic.

What are the environmental operating limits for deployment?

The switch functions between -10°C and 55°C, allowing use in typical indoor and many industrial settings where temperatures remain within that span.

How is the electrical connection arranged for conduit-based wiring?

The unit accepts M20 conduit entry, permitting standard threaded conduit fittings and protected cable routing into the enclosure.

Can it be used where dust and water ingress are a concern?

The device is rated to IP67, providing protection against dust ingress and temporary immersion in water for sealed installations.

What is the switching current capability for control circuits?

Each switch contact is rated for operation at up to 1.5A, suitable for many signalling and control-level loads.
