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.

The Photoelectric Diffuse Laser Sensor that Sees Everything!

The detection of transparent, highly reflective, shiny and dark objects has always been an issue for infrared and vision-based process control sensor. The sensors would suffer instability during detection and fail to detect properly, which isn’t what you what in an industrial processing and automation installation. To address this problem, the ever-innovative development engineers at SensoPart put on their thinking caps.

The Sensing Solution

The FT 55-RLHM Photoelectric Diffuse Laser Sensor with background suppression (BGS) was created to effectively and reliably detect target product surfaces of any kind and identify even the smallest objects with ease. This unique sensor features an operating mode known as ‘Detect all’ and it can cope with any type of targets including:

  • Shiny and reflective target objects
  • Transparent products
  • Black products on a black background

The FT 55-RLHM range can respond to all deviations from a given reference, including changes in an objects distance, differing surface finishes or even a deflected laser light beam, the most efficient sensor in this category.  In this mode, this impressive and versatile sensor has no blind zone and target objects can be detected from zero mm. Ideal for countless challenging detection applications such as automotive, metal processing, machine construction and packaging technology.

Small targets? No problem…

Small targets can be reliably and easily identified within the sensors defined detection range including objects at acute angles. This capable Diffuse Laser Photoelectric Sensor not only utilises the distance value but can also cleverly integrates the energy emitted from the target object itself during the detection process. This sensor can be used to check stack height such as identifying multiple product layers like stacks of cardboard packaging by detecting the presence of too many or too few layers.

Impressive Features

  • Detection of the smallest objects even at long distances (up to 1 m – model dependant)
  • Extremely stable presence detection even in challenging applications
  • No blind zone in ‘Detect all’ mode
  • Special mode for stacking height measurement
  • Easy to operate thanks to LCD display and feedback function
  • Two independent switching outputs
  • Configurable switching outputs -switch-on/switch-off delays and more
  • Fast set-up thanks to continuous distance indicator in display
  • Laser class 1 – for optimum security
  • IO-Link – a future-proof interface that meets the demands of Industry 4.0
  • Robust metal housing – sensor durability even in challenging processes

Into the Blue with SensoParts’ BlueLight Photoelectric Sensors

The detection of transparent, reflective and dark objects has always been an issue for your average infrared and vision-based process control sensor. To help alleviate this problem the clever people at SensoPart developed a solution.

BlueLight Photoelectric Sensors!

Transparent, glossy, curved, sloping and deep black products have always been difficult to detect, especially if you have budgetary constraints. Sensors would suffer instability during detection and fail to detect properly leading to their eventual upgrade with a far more expensive product, OK if you can afford it!

bluelight photoelectric sensors

Into the Blue

Blue light process control sensors offer much greater process stability than the usual red-light proximity sensors in challenging applications and are very cost-efficient. Difficult product detection scenarios can include a combination of several critical factors, such as black objects with a high gloss curved sloping surface and a wide detection angle, but even when faced with situations like this, the Sensopart Bluelight sensor range succeeds.

Why so Blue?

Increased detection efficiency is achieved with a higher intensity of blue light and the interaction of different light colours with the surface of the target object. The blue light emitted by these sensors is short-wave and doesn’t penetrate as deeply as a red-light sensor would, meaning that more light is reflected, a decisive feature when detecting poorly reflective and transparent objects.

Bluelight Photoelectric Sensor Features:

  • Reliable detection of highly transparent or strongly light-absorbing objects
  • Reliable detection at angles up to 90° (model dependent)
  • World’s first blue light sensor with background suppression in subminiature format
  • Absolute background suppression using SensoPart BGS technology critical background situations are no longer an issue

 

Model Variants
