S46HD Series with LIMIT-SWITCHES
46HD Series Helicalohm potentiometer can have Limit-Switch built in. Limit-Switch works as an alert and can prevent themechanical stopper from being fractured and it is also used as a compact automatic control unit.
There are basically 2 types depending on where it is activated. Unless being specified, circumscription type (b) is supplied.

Inscription Type (a)Circumscription Type (b)Limit-Switch is activated within effective electrical rotating angle(360°x n).

Limit-Switch is activated outside effective electrical angel (360°x n).
