Series T.C 235/236Hinged Safety Interlock Switch®Features & Benefits• Tamper-resistant … integral actuator arm preventsbypassing by operator.• “Positive-break” NC contacts … ensure circuitinterruption upon only 4.5° of guard displacement.• Watertight design … meets IP67 washdown andimmersion requirements.• Rugged, corrosion-resistant housing … tolerates themost hostile environments.• Meets rigid safety agency standards … IEC, BG, UL andCSA.• Four 90° actuator head positions … provide installationflexibility.DescriptionThe T.C 235/236 Series are designed for use with hingedmovable machine guards which must be closed for operatorsafety. Their tamper-resistant design and positive-opening NCcontacts provide a significantly higher level of safety thanconventional, spring-driven limit switches often used tomonitor hinged-guard position. Their IP67 rating make themideal for interlocking safety guards in hostile environments.OperationThe T.C 235/236 is a single-piece, electromechanical safetyinterlock switch which is designed to mount to a hingedmachine guard. After opening the guard only 4.5°, the unit’spositive-break, normally-closed contacts are forced to open bya direct (non-resilient) actuating mechanism. These positivebreakcontacts ensure circuit interruption (and machinestoppage).Part NumberT3C235-11ZT3C236-11ZT3C235-02ZT3C236-02ZAVAILABLE STANDARD MODELSContacts(Guard Closed)1 NO & 1 NC2 NCDescription*Hinged safety interlockswitch with actuating leverto right in rest positionTypical ApplicationsThe T.C 235/236 is intended for use as a safety interlockswitch on hinged, movable machine guards which, whenopen, expose operator/maintenance personnel to machinehazards.
