Product Usage Instructions
Sensitivity Adjustment:
The sensor has a sensitivity setting that can be adjusted using
a trimpot located next to the sensor’s signaling LED. Turn the
trimpot clockwise to increase sensitivity and counterclockwise to
decrease it.
Mechanical Installation:
Before installing the sensor, check the sensing distance to
ensure it can detect objects effectively. Securely install the
sensor to prevent vibrations that may affect its functioning.
Precautions:
- Avoid subjecting the connection cable to mechanical
stress. - Use M4 screws with cylinder heads for fixation.
- When installing with nuts, mark the mounting holes using a 4mm
drill, insert screws, fit nuts, and tighten without overdoing
it. - For installation with thread, choose a suitable location, mark
fixing holes using a 3.3mm drill, insert screws, and avoid
overtightening. - In harsh environments, contact the technical department for
guidance on a more suitable sensor for the application.
FAQ
What is Namur Sensor?
Namur Sensor is similar to conventional sensors but does not
have an output stage with a switching transistor. It is typically
used in potentially explosive atmospheres.

INSTRUCTIONS MANUAL
Magnetic Pick UP Sensor PM-K1-N-J
The sensor has a sensitivity setting that enables the detection of objects with reduced dimensions. The adjustment is made via a trimpot located beside the sensor’s signalling LED.
Before installing the sensor in its proper spot check the sensing distance, as if the object is outside the trigger sensitivity of the sensor it will not work and may cause failure of the process. After completing the installation check that the sensor is securely in order to avoid large vibrations that can influence the functioning of the sensor.
The following are some precautions that should be taken when installing the sensor:
Connection Cable: Avoid the cable connecting the sensor is subjected to any mechanical stress.

Fixating Screw:
We recommend using M4 screws (not included) cylinder head only.
Installation with Nut:
choose the appropriate place in the structure of the machine or equipment and place the sensor in the proper position to detect trigger, mark the mounting holes using a 4 mm drill, insert the screws on the sensor and go into the holes of the plate, fit nuts and hold them tightening the screws (do not overdo it).

In installations in harsh environments we recommend contacting our technical dept, to specify the sensor more suitable for the application.
Fig. 1
The magnetic pick-up sensor PM-K1-NJ is designed for applications where it is necessary to detect metallic objects in motion behind the fixed metal parts. The sensor has a magnet and a coil with eight thousand turns which generates a magnetic field and when the metal object passes through the sensor face, this magnetic field is changed, causing the sensor to change state.

Installation with Support: If the sensor is mounted in place of difficult access or require adjustment of sensing distance to the target drive, develop adequate support and use of the above methods for fixation. . Electric Installation: Cable Preparation The sensors are supplied with tinned ends now, but if the cable needs to be cut we recommend making the tips of the wires according to the drawing below:

Certification information: The certification process is coordinated by Inmetro (National Institute of Metrology and Standardization Insdustrial) that uses the ABNT (Brazilian Technical Standards Association) for the development of technical standards for various types of protection. The certification process is conducted by OCPs (Product Certification Body accredited by Inmetro), using approved laboratories for type tests on the products and issue the Certificate. For intrinsically safe the only laboratory accredited to date, is the Labex in downtown Cepel laboratories in Rio de Janeiro, where there are specialized facilities and technicians to perform the various procedures as required by the rules, even to conduct controlled explosions with representative gases of each family. Certificate of Conformity The figure below illustrates a certificate of conformity issued by the OCP NCC after the tests and trials carried out in laboratory:
