6500 Series Control Head Limit Switch Information
Electronically controlled 6500 Series Control Heads utilize limit switches (or optionally, proximity
sensors) in order to detect rotation. Depending on the type of unit (turnstile or ADA gate), the limit
switch for a direction may be on the left or the right hand side of the control head.

ADA Gate control heads use an oblong lobe shaped
limit switch cam. The point of the lobe needs to be
facing the index pin (bar with two springs) when the
cam is in the home position.
The limit switch for direction 1 is on the left and the
limit switch for direction 2 is on the right. In this
triggered after the cam leaves home position, which
re-engages the locking bar. The cam is still free to move
until it swings back to the home position.
Turnstile control heads use a triangular shaped limit
switch cam. One point of the triangle needs to be facing
the index pin (bar with two springs) when the cam is in
the home position. The two indents in the sides of the
triangle are for jigging purposes. It does not matter
which point is facing to the springs.
The limit switch for direction 1 is on the right and the
unit. The second switch triggers after the half-way point
of the rotation, which draws in the solenoid. This allows
the rotation to go to home but prevents the rotor from
backing in the other direction.
of this would be electronically controlled one direction turnstiles, turnstiles with counters and
turnstiles equipped with home position switches.
