Monitoring Of The Jaw Position Via Inductive Proximity Switches - SCHUNK KSP3-IM 100 Assembly And Operating Manual

5.4 Monitoring of the jaw position via inductive proximity
switches
The TANDEM KSP3-IM/KSP3-LH-IM clamping system is designed
for use with IN S-M8-1/IN S-M8-2 inductive proximity switches for
monitoring jaw positions.
The jaw stroke end positions for O.D. and I.D. clamping as well as
the exact clamping position can be monitored through recesses in
the base jaws of the clamping force block. The signals can be
directly processed by the machine control system.
The monitoring result is: The clamping force block is open or
closed (for I.D. or O.D. clamping depending on the application).
• Information on handling sensors is available at schunk.com or
from SCHUNK contact persons.
• Technical data for the sensors can be found in the data sheets
(included in the scope of delivery or at schunk.com).
The proximity switch used has reverse polarity protection and is
short-circuit-proof.
For the proper use of the proximity switches, observe the
following:
• Do not pull forcefully on the sensor cable.
• Do not subject the sensor cable to tensile strain.
• Install the sensor connection cable straight and do not twist it.
• Tighten the counter nut for clamping the sensor using a suitable
tool and moderate manual force.
• Do not exceed the permissible bending radius of the cable (→
catalog specifications)
• Position the sensor so that the signal LED on the sensor head is
clearly visible (with cover, LED is not visible).
• Prevent the proximity switch from coming into contact with
hard objects or with chemicals; in particular, nitric, chromic or
sulfuric acid.
Proximity switches are electronic components which can react
sensitively to high-frequency interference or electromagnetic
fields.
• Check that the cable is correctly connected and installed. There
must be sufficient distance between the switches and sources
of interference and their supply cables.
• Parallel switching of multiple sensor outputs of the same design
(npn, pnp) is permissible, though this does not increase the
permissible load current.
• Please note that the leakage current of the individual sensors is
accumulative (by about 2 mA).
