EX-Z Series Photoelectric Sensors – Small is Beautiful

Photoelectric Sensors come in a wide variety of sizes, shapes and variants including reflective and through beam all of which essentially perform the same purpose, the detection of objects crossing the path of the beam which then leads to a given response from the control system. This could be an alarm if an item is missing or a signal triggering another function of an automation and control process.

Big Things Come In Small Packages

For your average industrial installation there will typically be a suitable photoelectric sensor available, but when the application is very restricted in terms of available real estate, then you will need to look beyond the average sensor offering. The biggest challenge when designing and manufacturing miniaturised industrial photoelectric sensors is combining both the optical and electronic components into one housing, which as you can imagine is a complex engineering solution. Panasonic, with decades of experience with electronic design and miniaturisation were the obvious candidates to develop and manufacture a high-performance range of diminutive photoelectric sensors.

With a width of only 3mm, the EX-Z Series of Miniature Thru-beam Photoelectric Sensors is one of the smallest in the world that also contains a built-in amplifier making them ideal for mounting in tight spaces. This small but mighty range of miniature photoelectric sensors are not only small but have been designed to detect even the smallest objects with a fast response time and with the highest precision. The EX-Z series is especially suited to precise object detection within a limited and challenging installation space. Even though the housing of the sensor is only 3mm deep it contains all the essential technical elements, such as optics, electronics, indicator LEDs, and transistor output. A 2-metre cable is built-in as standard with special lengths being available upon request.

Packed with Technology

EX-Z Series - 3mm in width, fingertip sized!Although small in stature these Miniature Through-beam Photoelectric Sensors pack a powerful punch, with the ability to detect objects as small as 0.3 mm diameter without the use of an optional slit and identify objects as small as 1 mm in diameter at up to 500 mm distance (depending on the chosen model), a world class achievement among self-contained miniature photoelectric sensors. The low power consumption of these detection sensors makes them appealing to many industries and coupled with IP67 protection and their excellent vibration and shock resistance the EX-Z series is ideally suited for use in challenging and harsh industrial automation and control environments. Supplied as an emitter and a receiver pair. 3 stainless steel mounting brackets are also available separately along with a polyacetal spacer for through wall sensing, providing numerous mounting and installation options.

SicWave – 80 GHz Free-space Radar Level Detection for all Liquids and Solids

The storage of products such as grains, sugar, ore and liquids can take up a lot of space, typically utilising silo systems which can reach considerable heights. Measuring the level of product within these storage facilities can be difficult at the best of times where both the height and the media within can cause various issues with accurate level sensing. Similarly, production processes that involve stirrers and preparation tanks can create internal environments where accurately measuring the level of the contents within is challenging.

Dust and Foam Frustrations

Dust, moisture, foams, the build-up of residues and other obstructions within a storage or processing vessel can frustrate your average sensor, leading to down time, additional costs and frustration. What you need is a sensing solution that can deliver reliable level sensing results no matter how tall the silo or how demanding the process and the media involved prove to be.

A Laser Through Beam Sensor with the Edge

The Conventional infrared though beam sensors found in many manufacturing installations can generate unexpected malfunctions that could lead to many hours of investigation and maintenance to resolve.  Panasonic design engineers embraced this situation as a challenge, find a way to simplify this investigative process and make life easier for the operators and engineers involved in the tasks at hand, ultimately saving companies time, money and a lot of hassle!

Designed for use on manufacturing and processing lines, the HG-T Series Laser Through-beam Sensors feature a built-in self-monitoring function that diagnoses the current operational state and notifies the user when readjustment of established settings have drifted and when maintenance is required. The sensor determines its status and indicates Normal, Notification, Caution or Fault via its controller. When not in its normal status, the sensor identifies the cause of the problem and the corrective measures required, reducing equipment downtime and maintenance workload.

Finding the Edge

A HG-T Laser Through-beam Sensor installation, which consist of an emitter,  receiver unit and a controller, produces a flat, belt-shaped laser beam with a height of 10 mm which is ideal for tasks such as checking the contours of an edge, shaft diameters or the inside diameter of a product. The sensors have a sensing range of 500 mm, achieving a repeatability of < 1µm and have a linearity of less than ± 12µm over their measurement range, meaning that they are suitable for a wider range of applications than those infrared sensors with a shorter sensing distance.

Quick to install, the sensor heads are equipped with a beam alignment function to help speed up commissioning. Easy to set up by simply plugging the sensors into the controller unit which then automatically detects whether the emitter and receiver are connected correctly.

laser through beam sensor

Available in two different sensor head versions, both with the same capabilities and only differing in their physical dimensions. The receiver of the slim version is 10 mm narrower than the standard model making it suitable for installations with very limited space where the standard version would perhaps be too large.

Safety Light Curtains with Advanced Bluetooth Interface

Safety light curtains, or as they are often known as – light barriers, light grids and light guards to mention just a few alternatives are classed as Electro-sensitive Protective Equipment. Consisting of a transmitter and a receiver head, light curtains generate a field of infrared light between these heads which is classed as the detection zone.

Invisible Light Protection

Typically, these diligent devices are situated around access points to a piece of processing machinery, shutting down the device should a person, or a part of a person, cross the beams of the safety grid.  Advantages of a light curtain include reduced operator fatigue, when compared to mechanical options such as gates and barriers, and the subsequent upkeep of these mechanisms and simplifying maintenance and set-up times.

safety light curtain installation

Utilised across numerous industry sectors for many years, light curtains come in many shapes and sizes. Schmersal, renowned for their impressive range of Safety Light Curtains decided to add yet more functionality to these popular process safety devices by adding a built-in high specification Blue Tooth interface.

The Schmersal SLC440/COM Safety Light Curtain range with built-in Bluetooth BLE (BLE stands for Bluetooth Low Energy) is an active optoelectronic protective device that can provide real-time status and diagnostic data of the light grid on a smartphone or a tablet via a Bluetooth interface.

Ideal for Predictive Maintenance

The Bluetooth interface allows easy start-up using a smartphone or tablet with the integrated set-up aid. There is also the useful option of saving the data, which can then be used to document a repeat test or for predictive maintenance purposes. The transmission of data to smartphones / tablets (Android, IOS) is facilitated by an app developed by Schmersal.

NFC technology has been used successfully in the past when it came to recording and monitoring device diagnostic data, however it is limited to only a few centimetres. The Bluetooth BLE interface contained within the SLC440/COM Light Curtains can achieve a range of up to 100 times more, around 5 metres in total.

This means the BLE interface is perfect when the safety light curtain installation is in a relatively inaccessible position. Bluetooth BLE also offers a greater range of applications because not all smartphones or tablets are equipped with NFC. As Bluetooth is an international industrial standard, the SLC440/COM range can be used all over the world.

safety light curtain installation

Safety and Efficiency

The SLC440/COM Safety Light Grid with BLE are ideal for improving efficiency and availability in manufacturing processes as their status can be accessed easily and in real-time, meaning issues can be captured early. Status information and diagnostic data enables processes to be reactivated quicker, particularly in the event of a system shutdown if a hazard is detected.

It also represents an economical innovation as, compared to classic Bluetooth, BLE is characterised by considerably lower energy consumption and reduced costs at a similarly high communication range.

All of the SLC440/COM range of light curtains are available from Kempston Controls, give our sales team a call on +44 (0) 1933 411 411 or email them at sales@kempstoncontrols.com, or use the enquiry form below and let us help you select your ideal light curtain solution.
