The Omron D40ML series of safety interlock switches is a magnetic locking device with an imbedded RFID safety interlock switch.
The magnetic locking function provides process protection to prevent entry or access to a machine or area during a critical step of the machine process.
The RFID switch provides the machine safeguarding function that is a highly tamper resistant safety device that is in compliance with ISO 14119.
The combination of the magnetic locking device and the RFID interlock system has no moving parts to get jammed or damaged and therefore is less troublesome than magnetic reed switches or mechanical interlock switches.
The RFID actuators are available in either general coded or uniquely coded versions. The uniquely coded actuators allow the RFID code of a specific actuator to be taught into a specific switch for a increased tamper resistance.
Operation for stand-alone switches is certified for PLe/Cat 4. Up to 20 switches can be connected in series thereby reducing wiring costs. Series connected systems are certified for PLd/Cat.3.The residual magnetism retained by the magnetic lock acts as a light duty door latch thereby eliminating the need for a mechanical latching mechanism to keep the door closed.A multi-color LED provides a visual indication of the status for the locking device and the door monitor.
The D40ML is available in three different housing types; each with two different holding force options. The die-cast metal and plastic housing units are both available with either a 900N or 1500N holding force. Both units also have an IP67 protection rating.The stainless steel version is available with either a 600N or 950N holding force and provides an IP69K protection rating.The D40ML operates on 24VDC and provides dual channel safety outputs to your safety monitoring relay, safety controller or safety PLC.
The plastic body and more robust die-cast metal body switches will find many applications in the packaging, automotive and general industrial environment. The stainless steel version of the D40ML is well suited for food processing & beverage industries requiring the IP69K rating. I think you will find the Omron D40ML magnetic locking switch to be a great solution for many of your process and personal protection applications.
