Allen Bradley Guardmaster 440H Safety Hinge Switch, NO/2NC

The Rotacam is heavy-duty, hinge-actuated safety-interlock switch. It can be used as, or connected to, the existing hinge pin for direct operation of the switch. Machine power is isolated when the guard has been opened just 5°. For applications requiring a larger degree of operation, the internal cam can be adjusted from 5…11°.

Can be used as a hinge pin on light and medium weight guard doors
Isolates power within 5° of door movement (2° to operate 2N/C safety contacts, 3° to operate 1N/O auxiliary - which can be used to indicate which guard has been opened, or can operate an alarm)
Degree of operation can be customized with adjustable cam
Robust die-cast case, ideal for heavy-duty applications
Contacts 2 NC & 1 NO
Forced guided contacts - complies with EN 1088, IEC 947-5-1

these are not to be used for load bearing applications.

This Rotacam hinge switch from Rockwell Automation's Allen Bradley Guardmaster range protects machinery from damage and keeps staff safe. If someone tries to open a protected door, the Rotacam shuts off power to the equipment inside. Connect it to the existing hinge pin on light and medium-weight doors to operate the switch. When the guard is opened 5°, the switch isolates the machine power. This can be adjusted up to 11° for applications that need greater movement.

You'll find this switch in food processing, packaging and printing applications where automated assembly lines need to operate constantly. Tool manufacturing and machine construction also use safety hinge switches to protect staff from hazardous equipment. Measurement technology, process engineering and laboratories need them to protect sensitive equipment that's easily damaged.

This safety device can be used with Guardlink, a new safety linking technology from Allen Bradley Guardmaster.
Guardlink simplifies and reduces the connection time of the safety system, whilst providing real-time diagnostic information over Ethernet IP. This makes it simple to identify the location of the device that has tripped the safety system, thus reducing downtime, and improving the machines overall efficiency.
