Ask an Expert Industrial Sensors - Episode 8

Posted by John Appleson on Wed, Apr 15, 2015

This episode of Ask an Expert for industrial sensors examines and provides answers to interesting sensing questions we've received from customers just like you. We explore and answer these questions:

1. Magnetic sensor MB60-12GM50-E2: What is the performance of this sensor like if the sensing surface is less than 10 mm away from the sensor?

2. How does the magnetic field sensor 41FY1 work? Is it a two-part magnetic sensor?

3. What is the required target size for the inductive sensor NJ5-18GM-N-5M? Will a 1/8 in. wide keyway that is .03 in. deep on a 4 in. diameter shaft work?

4. I'm trying to connect an NBB5-12GM50-E0-V1 inductive sensor to a PLC, but I am unable to make the two work together correctly!

5. Do you have cable connectors? What about for specialty cable types?

How to Read a Sensor Connection Diagram

Posted by Tracy Molnar on Tue, Nov 05, 2013

Look before wiring!

Let’s talk about connection diagrams.  Although sensor hookup is typically simple – just a few wires – it’s always a good idea to consult the connection diagram before wiring to be sure you’ll end up with the outcome you expect.

My Old Industrial Sensor has 4 Pins

Posted by Tracy Molnar on Thu, Oct 17, 2013

…and the replacement only has 3 – can I still use it?

It’s always a good idea to double-check that a different-looking industrial sensor will work as a replacement for your currently-installed part, because looks can be deceiving.  Take for example the question above regarding the number of pins in a sensor’s connector.

Why Would I Use a NAMUR Output Sensor?

Posted by Robert Pasho on Thu, May 30, 2013

Proximity sensors and encoders can have NAMUR output

NAMUR is a type of sensor output that gives an on or off indication.  There are different reasons why you may need a NAMUR sensor.  I will go through some of them here.
