Finding the Model Number on Your Inductive Sensor

Posted by Eric Miller on Thu, Oct 01, 2015

One of the most important parts of integrating an inductive sensor into an application or ordering replacement parts is being able to identify the part and model number of the sensor. That is why knowing how to find the model number on your inductive sensor is so important. This is actually a fairly simple and straightforward process.

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?

Using AS-Interface to Control Pneumatically Operated Process Valve Assemblies

Posted by David Fink on Thu, Mar 05, 2015

15 common questions answered about AS-Interface and valve assemblies

1. What is the process valve assembly comprised of?

A typical assembly is a rotary travel valve such as a ball valve or butterfly valve mounted to a pneumatic actuator equipped with a dual position inductive sensor such as our model F31, a target which we call a puck, and a solenoid valve.

How to Connect a NAMUR Sensor to a Switch Amplifier

Posted by Robert Schosker on Thu, Feb 26, 2015

NAMUR sensors are used in hazardous locations, and can provide both explosion hazard and personal safety protection. NAMUR sensors and switch isolators are highly reliable and have proven-in-use characteristics, making them a perfect choice for safety-related applications when connected to suitable control circuits.

Most devices are independently rated with Probability of Failure on Demand (PFD) and Safe Failure Fractions (SFF) that enable them to be used in functional safety areas up to SIL2 or SIL3.. In this video, Product Manager Robert Schosker will show you how to connect a NAMUR sensor to switch amplifier KFA5-SR2-Ex2.W, and then test to ensure proper operation.

Ask an Expert Industrial Sensors - Episode 7

Posted by John Appleson on Thu, Feb 05, 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. I want to use a NBB1.5-8GM50-A2-V1 in a safety-related circuit. This circuit will overlap a safety light curtain. I want to use this sensor to monitor the safe position of a pneumatic slice when the light curtain is broken during the loading of a part. The prox signals will be monitored twice per cycle to ensure proper diagnostic coverage. Is it possible to wire two or more of these inductive sensors in a series if I need to monitor the position of more than one device?

2. Does Pepperl+Fuchs have a proximity sensor with a variable output where the output increases as the target cam moves away or toward the target area? The housing has a limitation of 10 mm x 8 cm with a sensing range of 1/16 in. to 1/4 in.

3. An NJ1.5-8GM-N sensor is used in a robot wrist tool changer. The tool is in a harsh environment. The cable is covered with a solvent-proof tube. Is this sensor available with a more durable jacket than PVC? Perhaps a jacket made from nylon impregnated polyurethane?

4. I am wondering what the sensing "cone" angle is on the ultrasonic sensor UB250-F12-U-V15. I have an application that needs to sense levels of liquid in a pan. The sensor would have to be placed close to the wall of the pan. How far away would the sensor need to be from the wall for a given sensing depth?
