Allen Bradley Guardmaster 440 L Series GuardShield Light Curtain, Sender & Receiver, 64 Beam(s), 14mm Resolution

Ensure sophisticated presence sensing for your machine safety application with the GuardShield 440L Finger Protection Safety Light Curtains and accessories by Allen Bradley Guardmaster.

The GuardShield family of safety light curtains are general-purpose devices for presence sensing. They can be used on hazardous machinery to ensure perimeter and access detection and point of operation detection, helping to prevent injury to personnel. Point of Operation Control light curtains (POC) are used specifically for finger, hand and arm recognition and should be placed close to the hazard where personnel interact with the machine. This type of safety system uses a transmitter which emits sequential pulses of infrared light to a receiver. When the beams are interrupted a stop signal is immediately sent to the machine.

These GuardShield Light Curtains are self-contained two-box Type 4 Electro Sensitive Protective equipment (ESPE). They have convenient DIP switch selectable Modes of Operation, located beneath a security door in the end caps, which offer advanced features such as:

• Fixed blanking (teachable)
• Floating blanking (one or two beam)
• Beam coding
• Start/restart interlock
• External device monitoring (EDM)

• 14mm resolution (finger detection)
• Two safety solid state and one auxillary non-safety outputs
• Easy maintenance with the Quick Disconnect cables (4-pin for the sender, 8-pin for the receiver)

• Robot cells
• Conveyors
• Presses
• Forming Operations
• Electronic Fences
• Workstations

Note: Installation and operation of this safety device must be in strict accordance with accompanying operating instructions.

When ordering both a sender and receiver are included. In addition, a sender cable and a receiver cable will be required. For suitable safety relays, see the "Minotaur" range of products (e.g 447-5587)
