T M M 996 21 22 5 contact contact Safety Switches 996 Industrial Hinge Operated Safety Switches utilize a rotating to provide a positive means of turning the control power off an access panel door gate guard etc be rotated open machine operation switch operating shaft is designed to be in line with the rotation of the door and uses the opening force of the door to rotate safety switch operating shaft When the access panel door guard etc is rotated to the position the normally contacts in the safety switch are mechanically forced turning off the control power in the machine the Since the switch contacts can only be closed when shaft is rotated to the closed position the machine cannot be until the door gate guard etc is closed 13.5 PIN Specifications glass reinforced self extinguishing shockproof providing double insulation Voltage Directive Directive entry entry not furnished endurance Cycle temperature range Switch is in compliance with standards UL508 CSA C22 2 nr 14 EN 60947 5 1 EN 292 EN 418 EN 1088 EN 60204 EN 60947 5 1 204 IEC 337 1 IEC 947 5 1 NFC 63 140 VDE 0113 VDE 0660 Positive Break Contacts are in compliance with standards EN 60947 5 1 EN 60947 5 1 IEC 947 5 1 VDE 0660 206 class Screws Operating Radius 65 according to IEC529 with self lifting pressure plates to OPEN the normally closed contact to CLOSE the normally open contact is in the normal position when door is CLOSED million operations 13 to 175 25 to 80 C Contact rating2 A 6 A600 Q3003 400 500 125 250 Order Information Specifications Operating Short Circuit Max Max 996 Thermal Plastic N C VAC 300 VDC3 fuse Each electrical rating is an individual maximum and cannot be exceeded Configuration POSITIVE DOUBLE BREAK CONTACTS Electrically isolated contacts allow different voltages placed on contact poles UL508 M 1 pins 1 2 M4 8mm Screw Tightening 7 inch lb 0.8Nm Safety circuits must be connected to the normally closed NC 11 12 or 21 22 The normally closed contacts are when the door is rotated past 4 and normally open contacts 13 14 are closed when the switch is rotated 8 Normally open contacts are for indicating circuits and not for use in the safety circuit Mount the switch using tamper resistant fasteners not Always use washers under the switch mounting to prevent the fasteners from pulling through the mounting holes The head of the switch can be rotated in 4 x 90 degree steps 4 different shaft rotating positions To rotate the head the 4 head attachment screws rotate the head into proper position reinsert the head attachment screws It is the head be locked into position by replacing of the 4 head attachment screws with tamper proof screws provided The switch is to be used with the rotating hinge pin of the door the Hinge Operated Safety Switch to the machine at door swing centerline Extend the door hinge pin into the Operated Safety Switch operating tube using the M4 screw provided Verify operation of the entire assembly the operating point for the normally closed safety pin operating tube assembly to permanently lock the pin into the operating tube using the roll pin provided
