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?

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?

Ask an Expert Industrial Sensors - Episode 6

Posted by John Appleson on Wed, Nov 19, 2014

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'm looking for an ultrasonic distance sensor to beam a signal to the top of a heavy steel column on an elevator (6 meters height). The column base might have some slack jerk. Can fog, gas, vapor, or loud noises affect the ultrasonic sensor?

2. I need updated software to program UC3000 ultrasonic sensors. Is there an update that will allow us to set up these sensors in a Windows 7 program?

3. I would like an ultrasonic sensor that can reliably detect falling objects in a harsh environment (mining operation). We are trying to set off an alarm when there is rock-fall.

4. I have an RFID controller IC-KP-B17-AIDA1 with 4 read heads. We are hooking them up to a 24 VDC power supply and need to know what size/type of fuse to put on the incoming side?

Ask an Expert Industrial Sensors - Episode 5

Posted by John Appleson on Thu, Sep 18, 2014

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. What is the slope of the output characteristic, and what is the linearity error value for inductive analog sensor NBB5-18GM60-I3?

2. Are inductive analog sensors, such as the NBB5-18GM60-I3, capable of detecting aluminum at a reduced distance, and do you have a correction factor for this?  

3. Photoelectric sensor MD17/73 has a plastic retaining nut to secure it on a mounting bracket. Is it possible to order just the retaining nuts? Due to location, they get damaged or lost and we don't want to replace the entire switch.

4. Photoelectric sensor - I'm trying to sense clear fluid being shot out of a small 0.11 in. diameter hypodermic needle. What sensor, if any can detect fluid flow start and stop? The water stream is only approximately 0.09 in. in wide.

5. Thru-beam photoelectric sensor - I need to detect wire strands as they pass a sensor. The strands are less than 1 mm diameter, moving up to 5 in./s (~0.13 m/s). Is a thru-beam  photoelectric sensor the best option? Which model would be best for my application?
