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.

Radiant heat from manufacturing processes in high-temperature environments can present a challenge for optical sensors used in automated production facilities. Excessive heat in melting, pouring, or similarly demanding industrial applications that exceeds a sensor’s temperature specifications can degrade the measurement quality, damage sensor diodes, and cause unwanted disruption to production. Usage statistics show that for every 18 °F (10 °C) increase in temperature, the diode lifespan of optical sensors is reduced by up to 50%.

There are times when you need only an intrinsic safety barrier or surge protection to get the job done. But what if you need more than just a component, something more customized, something like a complete system solution—including documentation and certification? Sure, you could always build your own and have it certified yourself. But it's time consuming, and the number of approval standards and certification bodies is enormous. You really need to be focusing on keeping your plant running.
Even though POWER24 has been around for years, nobody really talks about it. It is a rarely used and little-known part of the latest specification that allows AS-Interface to run at 24 VDC. It has taken a while for the right number of components to be designed to the POWER24 specification for it really to be considered useful for most modern-day material handling and assembly applications.
What is the principle behind ultrasonic retroreflective mode sensors? How do they work?
Retroreflective mode uses the same type of design as diffuse mode sensors, such that a single housing contains both the transducer and the evaluation electronics, allowing one sensor to operate as both an emitter and receiver. Much like diffuse mode sensors, retroreflective sensors emit a three-dimensional sound cone which creates a beam angle that defines the sensing range. However, instead of calculating the distance to a target object, retroreflective sensors are set to a specific constant value based on an unchanging distance to a reflective surface like a wall, plate, or conveyor belt. This distance between the sensor and the surface serves as a reference. The sensor measures the amount of time between the emission of a sound pulse and its return echo from the reflective surface. If there is a change in the amount of time or if the echo disappears entirely, this indicates that a target object is present.

What are the differences between absolute and incremental rotary encoders? Which one do I use when? These questions come up all the time. Our customers want to know.
Rotary encoders in general connect to a shaft and output pulses as the shaft rotates. You can determine the speed of an object based on how many pulses there are per revolution. The number of pulses that make up one full turn of the shaft determines the resolution. Incremental encoders have a resolution of up to 50,000 pulses per revolution (ppr) while absolute encoders have a resolution of up to 16 bits or 65,536 ppr.

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:
- How do I get a narrower sound cone on an F260 series ultrasonic sensor?
- Is AS-Interface "data decoupling" the same as "filter integrated"?
- Can I use a diffuse mode photoelectric sensor to detect marks on a steel rivet?
- What is the output stage used for on an inductive sensor?
What is WirelessHART?
WirelessHART is a wireless communication network designed especially for sensors used in process automation. It connects individual sensors to a distributed control system (DCS) or asset management system.
