Now available from Guardmaster is the Trojan T115, dual channel safety interlock switch, said to help designers achieve improved safety integrity levels, as mandated in IEC61508 and IEC62061.
The Trojan T15 integrates two sets of safety contacts and positive mode reliability in a design that is only 75mm long, but provides ample space for wiring.
The new shorter Trojan T15 allows machinery to be safeguarded in full compliance with European standards EN 1088, EN 60947-5-1, EN 60204-1 and EN 292. Developed to meet both the current and future requirements of the safety system designer, it provides characteristics required from a small safety interlock switch, such as dual channel operation, forced guided contacts and a tamper-resistant mechanism, without incurring cost or size penalties for functions that are not required.
The Trojan T15 is a tongue-operated safety interlock switch, designed to fit at the opening edge of sliding, hinged or lift-off guards. A 180° rotatable head, movable only by releasing the cover screws, gives the Trojan T15 four actuator entry points with only two actuator slots. This makes the unit versatile for installation purposes. In addition, the provision of an entry plug with each switch allows the Trojan’s unused slot to be sealed, preventing dirt and debris from contaminating the switch mechanism.
The Trojan T15 is encased in a tough plastic housing which is IP67 rated to allow for the high-pressure hose downs that are undertaken in the food industry and in other hygienically sensitive areas. It is available in two model types, with M20 and PG11 conduit entries, both of which can be conveniently sited in one of three optional positions, on the side or the end of the safety switch.
