TKA38 cable carrier TKA Series

The TKA38 has an inner height of 26 mm and an outer height of 36 mm. It is available in 6 fixed inner widths: 25 / 38 / 58 / 78 / 103 / 130 mm. The outer width is the inner width plus 16 mm, so 41 to 146 mm. The pitch is 38.5 mm and there are 7 bending radii (KR): 70 / 95 / 120 / 145 / 170 / 195 / 230 mm.

The installation height (H) follows from the radius: with KR 70 mm it is 176 mm, with KR 230 mm it is 496 mm. Choose at least the radius your thickest cable requires; you will find it in the cable's datasheet. The thickest cable or hose may be 20 mm. For the inner height, calculate with the cable diameter plus 10% clearance.

By inner height, the TKA38 is number 2 of the 4 types in the series, from small to large. One size down is the TKA30: 20.5 mm inner height (5.5 mm less), for cables up to 16 mm. One size up is the TKA45: 36 mm inner height (10 mm more), for cables up to 28.5 mm. The longest travel length in this series is achieved by the TKA55 (150 m); the TKA38 goes up to 120 m.

Self-supporting, with the upper run free above the lower run, the TKA38 reaches up to 3.9 m travel length, 10 m/s and 50 m/s². For longer strokes it runs gliding, with the upper run on the lower run in a guide channel: up to 120 m travel length, 2.5 m/s and 20 m/s².

The weight of cables and hoses (additional load) may be up to 5 kg/m in a self-supporting arrangement, according to the load diagram in the catalogue. Vertical installation, hanging or standing, is also possible. Lying on its side is also possible. A rotating arrangement is not possible.

Dividers of 2 mm separate the cables across the width; the smallest centre-to-centre distance is 7 mm. With a 2 mm shelf you lay cables in layers above each other, so thick and thin cables do not touch. You open the TKA38 on the inside or outside radius to lay in cables.

The TKA38 has universal end connectors (UMB). You can add strain relief (comb or C-rail) to the end connectors.

According to the type data, the TKA38 is intended for indoor use. It is made for dirty environments. The type data also lists environments with chips.

You choose an enclosed cable carrier such as the TKA38 when your cables really need to be covered, for example against chips. If that is not necessary, an open UNIFLEX Advanced with a comparable inner height, such as the UA1455 (26 mm), is usually the simpler choice. Wisman Techniek supplies the TKA38 cut to length and, if required, complete with cables, assembled in Ruurlo.
