HHD100 series half height turnstiles (double pass) are an ideal solution for pedestrian crossings that do not have security guards and require medium level security. It is designed to allow only 1 person to pass through each passage. Transition is provided with 3-arm (120 degree) triangular rotor or 4-arm (90 degree) square rotor options.

Main factors such as modern microelectronic card, mechanism processed on CNC machines, non-contact position sensor technology, adjustable damping ratio with hydraulic damper, automatic centering with cam mechanism and coating of the mechanism against rust ensure that HH100D series turnstiles operate problem-free for many years.
