IEC Test Equipment Performance Tester For Proximity Switches With Intergrally Connected
Cablea
Standard:
IEC 60947-5-2 ‘Low-voltage switchgear and controlgear - Part 5-2:
Control circuit devices and switching elements - Proximity
switches’ Annex C.8
Application:
It is used to test the structural strength performance of various
proximity switches and photoelectric sensors with integral
connecting cables, ensuring that the connecting cables and switch
positions are relatively fixed. IEC Test Equipment
The purpose of these tests is to ensure integrity of the cable
anchorage during transit handling and installation. Once installed,
the proximity switch and cable should be fixed relative to each
other.
C.8.1 .1 Pull test
The cable shall be subjected to a steady pull along the axis of the
cable entry, applied to the insulating jacket of the cable for a
duration of 1 min.
C.8.1 .2 Torque test
The cable shall be subjected to a torque of 0,1 Nm or limited to
the value giving an angle of torque of 360°. The torque shall be
applied to the cable, clockwise for 1 min and then counter-
clockwise for 1 min, at a distance of 1 00 mm from the proximity
switch entrance.
C.8.1 .3 Push test
The push force shall be applied along the axis of the cable as
close as possible to the cable entrance.
The force is increased slowly to 20 N. The force shall be applied
for 1 min for each time and with a 1 min pause between
applications.
After the tests, no visible damage of the cable entrance sealing
means and no displacement of the cable shall be observed.
C.8.1 .4 Bend test
The cable shall be loaded and bent in the following manner:
a) Suspend a 3 kg mass by attaching it to the cable 1 m from the
cable entrance and with the axis of the cable entrance vertical.
b) Tilt the proximity switch 90° to cause a 90° bend in the cable,
maintaining that position for 1 min.
c) Tilt the proximity switch 90° in the opposite direction relative
to vertical so as to cause an opposite 90° bend in the cable,
maintaining the position for a duration of 1 min.
Feature:
The equipment adopts advanced PLC intelligent control system, touch
screen humanized operation interface to make recording and display
more accurate; with preset test times, test speed, test stroke,
pull force setting and other functions. Can be analyzed by the data
record whether the test sample is qualified or not.
