Worldwide under various environmental and operational conditions, the UNISTAR HR family proves market leading quality and reliability. All family members offer watertight and dust-tight boxes certified according to IP67. The unique and SIL4 certified design of UNISTAR HR is proving excellent reliability and highest availability in daily operation.

Technical description:

Motor unit and DLD (drive, locking, detection) unit are split into two individual IP67 certified boxes. This allows versatile installation.
The motor unit with hydraulic drive is capable of operating up to four DLD units installed in a turnout.
In case of distributed drives in a turnout, identical DLD units are applied.
The throw of each adjustment level can be individually adjusted

The connecting rods compensate for thermal expansion and contraction of the switch points without affecting the end position adjustments. Integrated pressure heads positively close the switch points against the stock rail.
