For LINAK® industrial actuators there are three cable types available: a separate power and signal cable, a single cable for both power and signal, and a Y-cable. In this video, our expert Hunter Stephenson explains the difference between a power and a signal cable, and how customisation can unlock the benefits of simple plug & play installation.
What are the different cable types for electric linear actuators?
Generally, for LINAK® industrial actuators there are three cable types available: separate power and signal cables, a single cable for both power and signal, and a Y-cable.
Having separate power and signal cables increases flexibility and makes it easier to integrate actuators in various machinery. For example, you can have a power supply in one end and a motor control in the other end. For actuators with lower current consumption, a single cable can handle both power and signal. In other cases, an actuator may have a Y-cable, which is connected to the two connectors in the actuator, and a single plug for both power and signal in the other end.
What is a plug and play solution?
A plug and play solution is an easy-to-use option for quick and hassle-free actuator integration, which you can achieve by choosing a customised cable along with your industrial linear actuator. In most cases, all you need is an actuator with the preferred cable option and two bolts (one for the back fixture and one for the piston rod eye) – and your application will be up and running in no time.
How does LINAK test cables?
LINAK industrial actuators are always tested with the cable mounted before leaving the production. This ensures that the actuator connection is correct and working.
For an actuator to comply with the IP69K rating (Ingress Protection), there must always be an overmolding at the end of the cable.
To retain the high IP rating, it is important to take precautions and design the wire connection to the machinery in a way, where the cable end is kept inside a closed, protected area. This will prevent water spraying from entering the connector and further into the actuator.
On LINAK industrial actuators, the cabling and housing are designed, so the cable can be replaced without affecting the IP rating.
To ensure reliable signal quality and to prevent power loss, it is recommended that you choose the shortest cable length possible.
When looking at linear actuator connectors, Deutsch DT or AMP Superseal are often preferred for LINAK solutions in industrial machinery. These actuator plugs are designed for use in harsh environments, and the silicone rear wire and interface seals allow the plugs to withstand condition of extreme temperature, adverse pressure, or humid conditions.
To retain the high IP level, it is important to take precautions and design the wire connection to the machinery, so the cable end is kept inside a closed, protected area.
For an actuator to comply with IP69K, there must always be an overmolding at the end of the cable to avoid water spraying into the plug from where it might enter the actuator.
When deciding on a cable type to connect your actuator with your machine, always have this in mind: Define the cable requirements, remember to shield the cable, and avoid bending the cable.
