AVAILABLE STANDARD MODELS Contacts Part Number* Description (Guard Closed) ® Hinged safety interlock TESZ1102/30 1 NO & 2 NC switch for 30mm width TESZ1110/30 3 NC Description extruded guards The TESZ Series are designed for use with hinged movable Hinged safety interlock machine guards which must be closed for operator safety. TESZ1102/35 1 NO & 2 NC switch for 35mm width TESZ1110/35 3 NC Their tamper-resistant design and positive-opening NC extruded guards contacts provide a signiŢcantly higher level of safety than conventional, spring-driven limit switches often used to Hinged safety interlock TESZ1102** 1 NO & 2 NC monitor hinged-guard position. Their compact, low-proŢle switch for 40mm width TESZ1110** 3 NC extruded guards design and IP65 rating make them ideal for interlocking hinged safety guards in industrial environments. Designed to Hinged safety interlock mount directly on the hinged guard and its stationary frame, it TESZ1102/45 1 NO & 2 NC switch for 45mm width is easy to install on a wide range of guard styles and sizes. TESZ1110/45 3 NC extruded guards *Includes hinge assembly with switch, switch actuator and an Operation additional hinge assembly (without switch or switch actuator). The installed TESZ features an integral electromechanical **Available with stainless-steel hinges. (Please consult factory) switch element which is actuated when opening a hinged machine guard. After opening the guard only 4°, the unit’s AVAILABLE ACCESSORIES positive-break, normally-closed contact(s) are forced to open Part Number* Description by a direct (non-resilient) actuating mechanism. These Hinge assembly (without switch or switch positive-break contacts ensure circuit interruption and TESZ/S/30 actuator) for 30mm width extruded guards machine stoppage.
