Servo Motor IEC Performance Tester For Proximity Switches

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.
