Self-assembly instructions for safety edges
(ENT-R, ENT-20, ENT-7, ENT-S)
Safety edges (sensors) in combination with a switching unit (signal processing) are components of a safety system (protection system for person detection).
The system, or more specifically the safety edges, are used to safeguard shearing and crushing points on power-operated doors, gates and similar automatic
fixtures. The safety edges can be installed in any horizontal or vertical position, either singly or in combination.
Standard
Top, rubber profile closed:
- 1 end cap
- Profile chamber sealed
Bottom, rubber profile open:
(= no end cap and switching
chamber not sealed)

Measuring the safety edge
2.1
Trim aluminium profile to match length of protected area and plan type and manner of cable feed-through, drill holes (counterbores) and profile holders.
Aluminium profile length = Rubber profile length (L)
Trimming the rubber profile
2.2
L
5 mm
Using the rubber
shears, trim the rubber
profile to the desired
length L.
The switching chamber for the contact strip must not be damaged unnecessarily as incoming water may impair the safety function
of the strip.
For the cable feed-through,
make a small hole (1/10 mm
smaller than the cable diame-
ter) hole punch pliers about
5mm from the edge.
Option for vertical applications
(dependent on enviromental conditions)
End caps on both ends
Trimming the contact strip
2.3
L - X
Trim the contact strip to length (L – X). Be sure to cut at right angles!
The contact strip is shorter than the rubber profile
by the length of the end pieces used:
