Configuration tip: voltage

For smooth commissioning we recommend sizing your power supply to the maximum current consumption. We will gladly configure your actuator at the factory with the appropriate cable length and connectors. A 1‑m connection cable is included as standard. The quick start guide explains the cable wiring. The actuator features an integrated load cut‑off that automatically stops the actuator when current consumption increases.

Configuration tip: force

In the standard version the NTS1 spindle actuator has 600 N of force and a maximum speed of 13 mm/s. Select your force and speed combination to suit the application: with 600 N you can reliably move loads up to 60 kg. In hinge‑ or guide‑supported applications the design carries part of the load, reducing the required drive force.

Which force is required?

Below 600 N – sensitive applications such as windows or hatches
Up to 600 N – medium tasks such as skylights or ventilation openings
Above 600 N – heavy tasks such as machine covers or large gates

Configuration tip: speed

The speed indicates how quickly the spindle actuator travels its stroke length (mm/s).

Slow: precise control, gentle movements, higher loads
Fast: short cycle times, high response requirements

Calculate movement time

Formula: speed = stroke length / time
Example: 200 mm / 20 s = 10 mm/s

Note that higher speed often means lower force. Always consider stroke, load and speed together.

Available stroke lengths

The NTS1 is available in seven pre‑configured stroke lengths. Each actuator can be continuously adjusted to the desired stroke length. Intermediate and special stroke lengths are possible for custom solutions.

Configuration tip: stroke length

The stroke length defines how far the actuator extends and retracts.

Determine how much travel the actuator needs in your application.
The end position can be continuously adjusted on every NTS1 actuator (see instructions page 4). Shut‑off is via precise microswitches.
If blocked, the integrated load cut‑off protects the actuator and the application.
As the stroke length increases, the total length of the actuator increases.

Dimensions of the actuator:
width 44 mm | height 71.4 mm | length 180 mm + stroke length.
Example: with a 300 mm stroke length the total length is 480 mm.

Optional stroke length modifications

Factory setting of stroke limit as specified
Special stroke lengths, e.g., 120 mm, to achieve a shorter installation length
Short‑stroke versions under 100 mm for compact installation spaces
Long‑stroke versions above 600 mm (depending on force/application)

Available stroke lengths of the NTS1 in mm

Stroke length continuously adjustable 0 – 100 mm

Synchronous version and signal contacts

In many applications electric actuators have to be integrated into control systems. This is the case, for example, with synchronously operated flaps, safety‑related functions or automated processes.
Problem: integration often requires additional control units.
Solution: with the NTS1, synchronous operation and signal contacts can be integrated directly. This significantly reduces programming, installation and coordination effort.

Application of dry signal contacts

Dry signal contacts reliably monitor the end positions of the actuator and report its status directly to the building or machine control.

Safety monitoring: immediate notification if, for example, a window is accidentally open increases protection against break‑in or weather damage.
Automation: automatically starts ventilation as soon as the actuator is extended.
Process reliability: a clear status message (OPEN/CLOSE) ensures that, for example, extraction flaps are only active when open.

Application of the synchronous version

The synchronous version ensures exact synchronous operation of two identical NTS1 actuators.

Even force distribution: prevents damage due to uneven loads.
Increased operational safety: if one actuator triggers the load cut‑off, the second one switches off automatically to prevent mechanical damage.
Durability: active protection against asynchrony increases the service life of the whole system and reduces maintenance effort.

Installation of the NTS1 spindle actuator

Installation instructions and accessories

The NTS1 is supplied with a U bracket as standard. Thanks to a well‑designed overall concept, installation time is significantly reduced. Installation is straightforward and is described in detail in the operating instructions. Please follow the instructions in the manual to install the actuator correctly. Installation must be performed only by qualified personnel.

Scope of delivery

NTS1 spindle actuator with connection cable (1 m)
U bracket with 2 T‑slot nuts and 2 Phillips screws
Clevis bracket with M5 screw and self‑locking nut
Integrated control in the actuator

Mount the NTS1 quickly and safely

Screw on the U bracket.
Insert two T‑slot nuts into the actuator’s dovetail groove and attach the actuator to the U bracket.
Attach the load to the push tube, e.g., with the supplied clevis bracket.
Make the connection via open leads (DC or AC, depending on the version).
Run the actuator several times, test the limit shut‑off and adjust the stroke length continuously if necessary.

The supplied U bracket ensures secure mounting and allows flexible movement in dynamic applications. An M6 eye bolt is preassembled on the push tube at the factory. This can be adjusted or replaced with customer‑specific accessories if necessary. Thanks to the well‑designed construction and proven components, installation is quick and reliable.

Electrical connection (12 V, 24 V, 230 V) and load cut‑off

Continuously adjustable stroke in five steps

In five steps you adjust the NTS1 stroke length precisely for your application. The detailed description can be found in the operating instructions on page 4.

Unscrew the cover cap
Fully extend the push tube
Secure the adjusting ring twice
Set the desired stroke length
Screw the cover cap back on

Load cut‑off

The integrated load cut‑off continuously monitors drive current. If current consumption exceeds the permissible limit, the NTS1 switches off and thus protects the motor, gearbox and connected components.

Dry signal contacts

Optional signal contacts reliably report the end positions of the actuator to higher‑level controllers (max. 250 V / 1 A). You thus get precise feedback, for example, for safety‑relevant releases, status indications or to control automated processes.

Once the actuator reaches the respective end position, the associated dry contact closes. The two leads per end position are connected directly to the appropriate input of your controller.

Voltage	Color OPEN contact	Color CLOSE contact
230 V AC	Blue / violet	Red / white
24 V DC	Gray / violet	Red / white

Note: The contacts are not switched during a load cut‑off or if no supply voltage is present at the actuator.

Connecting the synchronous version

With the optional synchronous version, two NTS1 spindle actuators can be operated in parallel. Simply connect the two actuators via the pink and orange control leads. The integrated control ensures that both electric actuators travel precisely and evenly.

Ideal for applications where particularly large flaps, skylights or windows need to be moved. Higher forces can also be mobilized than a single actuator can provide. Synchronous operation enables a reliable, precise and space‑saving solution without any external controller.
