TRANSCRIPT
The SGS won't leave you high and dry!
The SGS is a bistable safety switch with remote reset facility.Once actuated, the SGS remains switched until it is eithermanually reset at the plunger or via external control of theintegrated solenoid reset function.In its durable plastic housing with three cable entries, the SGSis an outstanding economical alternative to the limited andoften costly solutions previously available to the market.
The SGS can be used wherever specific (manual or electrical)resetting action is required, e.g. in elevator construction, windpower equipment and wherever safety is of paramountimportance.
SGS applications include:• Elevator governors (speed limiter)• Monitoring of emergency over-ride operation• Mechanical engineering applications where controlled reset
of the switch is required• Applications with limited access• Remote monitoring and reset at distant sites.
Features:• Plunger indicates switch status• Plunger groove for manual reset• 2 Versions – 230 V AC and 24 V DC• Reset via built-in solenoid
actuators• 3 Cable entries M20x1.5• 2NC (forced disconnect)
contacts• Contact opening
