What is a single-entry or a single cable gland?
In general, all cable glands are used to insert a cable or insulated conductor into a housing. The housing belongs to a device, machine or control cabinet.
LAPP single-entries or single cable glands are cable glands designed for inserting a single cable into a housing.
Easy handling and high ease of assembly are desirable for practical use of a single-entry. The electrician must be able to assemble a cable gland easily.
For a secure fit in no time at all!
LAPP multi-entry systems, by contrast, are cable glands with which multiple cables can be safely inserted.
What are product groups within the single-entries?
At LAPP, we differentiate between the various single-entries according to their material:
Which cable gland is suitable for which application?
The application possibilities for cable glands and special single-entries are varied and individual. It is almost unthinkable to make a general statement as to which product is suitable for which application area.
The fact is that in addition to quality, the correct use of a cable gland is the most important factor for functional reliability. For this reason, we would like to remind you to observe all relevant standards for your intended application.
But how do you select the right cable gland for your application?
We have compiled a small checklist that can be used to answer a few questions in advance.
- Which connection thread is required (metric, NPT, PG)?
- What thread size is required (e.g. M 20)?
- Is compliance with certain standards or special product certification required (e.g. UL or VDE)?
- What is the temperature range that the product will be exposed to?
- Which IP protection class should be available, depending on the environmental influences?
- Are special product properties required that a conventional cable gland does not cover (e.g. much higher strain relief, special bending protection for the cable, etc.)?
- Is more than just one cable to be fed through?
What types of threads are there for cable glands?
LAPP basically offers you single-entries with the connection threads listed below. Depending on the through hole in your application, you will need a suitable thread on your cable gland. The thread types differ in terms of their thread lengths (in mm or inches), their flange angle (60° or 80°) and the number of thread turns.
The DIN 46320 standard for cable glands with PG thread was withdrawn on December 31, 1999. It was replaced by DIN EN 62444 for metric cable glands.
As a result, only cable glands with a metric connection thread are to be used for new plants and devices from the year 2000. This changeover not only affects cable glands, but also all housing systems and devices in which cables and wires need to be inserted.
For the time being, the PG thread sizes PG 7 to PG 48 have been replaced by the metric threads M12
to M63. Further sizes have subsequently been added to DIN EN 62444
so that a range from M6 to M110 can now be covered.
As a safety standard, DIN EN 62444 forms the basis for the technical requirements for a cable gland. It is more than a design standard with dimensions, such as the superseded DIN 46319 or DIN 46320.
The metric thread dimensions are standardized across Europe according to DIN EN 60423.
The NPT nominal sizes are primarily required for the North and South American markets.
The PG connection thread (armored conduit connection thread) with its 10 dimensions has been around for a very long time (previously DIN 46320 for cable glands with PG thread). However, at the end of the last millennium it was replaced by the metric thread.
The PG thread has now been largely replaced in the field of cable glands, but PG products may continue to be used for replacement measures.
Which metric thread size is the right one?
Which threaded borehole for which metric thread size?
Metric thread according to EN 60423 (for screw connection according to IEC 62444)
| Nominal size | Outer diameter | Pitch | Core diameter inner thread | Borehole diameter |
|---|---|---|---|---|
| M6 x 1 | 6 | 1 | 5.2 | 6.0 + 0.2 |
| M8 x 1 | 8 | 1 | 7.1 | 8.0 + 0.2 |

| M12 x 1.5 | 12 | 1.5 | 10.6 | 12.0 + 0.2 |
| M16 x 1.5 | 16 | 1.5 | 14.6 | 16.0 + 0.2 |
| M20 x 1.5 | 20 | 1.5 | 18.6 | 20.0 + 0.2 |

| M63 x 1.5 | 63 | 1.5 | 61.6 | 63.0 + 0.4 |
| M75 x 1.5 | 75 | 1.5 | 73.6 | 75.0 + 0.5 |
| M90 x 2 | 90 | 2 | 88.8 | 90.0 + 0.5 |
| M110 x 2 | 110 | 2 | 108.8 | 110.0 + 0.5 |
Which clamping range for which metric thread size?
The following overview helps you to choose the correct metric thread size. The clamping range of a cable gland indicates which minimum and maximum outer diameters a cable should have to be inserted in order to guarantee strain relief and the specified IP protection class.
Example: As a result, the clamping range of an M 12 is 3.5 – 7.0 mm.
How does a cable gland seal?
When the cable gland is tightened, the cable is gently fastened and sealed firmly by inserting it into a housing. The sealing materials prevent dirt and moisture from getting into the transition from the cable to the cable gland (sealing on the cable side) and from the cable to the housing (sealing on the housing).
How is the sealing achieved?
Housing side:
Plastic cable glands up to M 32 have sealing lips that deform in such a way that they allow very high sealing on smooth housing surfaces (IP 68/69). For larger metric thread sizes, metal cable glands and also for painted, anodized or powder-coated housings, O-rings are usually used to seal the housing even more securely.
On the cable side, various sealing rings and sealing inserts ensure optimum sealing of the cable.
Can more than just one cable be inserted through a single-entry?
Of course! Simply by using a multiple sealing insert.
The high elasticity of the sealing insert material enables gentle clamping of up to 16 cables and thus a very scalable packing density. There is no need to replace your current cable glands or adapt the boreholes in your applications.

For pre-assembled data cables:
For data cables with already mounted connectors, it is best to use the slotted SKINTOP® DIX-M AUTOMATION sealing insert. With this multiple sealing insert, you can easily feed your data cable assemblies through the cable gland thanks to the longitudinal cut (all common connectors fit through the domed cap nut). Depending on the variant, the insert has several optimally sealing pre-holes with a defined clamping range.
For insertion of up to 30 cables regardless of type:
Our engineers at LAPP have developed the innovative SKINTOP® CUBE system for pre-assembled cables of all kinds (including AS-I bus cables). It consists of a frame and quick-locking modules, which are inserted into the frame. Each of them consists of two halves of a module holding a cable. This enables the assembly clamped with the module to be routed through the generous frame of the multiple cable gland and quickly fastened to it. Individual replacement is possible without effort at any time.
