Getting the Right Harsh Environment Photoelectric Sensor

Photoelectric Sensor Targets Harsh Environments

Banner Engineering Corp. repackaged its TM18 EZ-BEAM photoelectric sensor for use in heavy duty environments. With its nickel-plated, die-cast zinc metal housing and completely epoxy encapsulated electronics, the TM18 achieves an IP69K rating. This design provides the durability and resistance for harsh industrial sensing environments, such as those with high pressure washdowns.

For easy alignment to a variety of targets, the photoelectric sensor is available in opposed, polarized retroreflective, diffuse and fixed-field (background suppression) modes.

The unit has a right angle shape, an 18-mm threaded barrel mount and integral all metal M12 quick disconnect. Its metal housing provides the sensor immunity to electro-magnetic noise and improved ability to withstand interference from fluorescent lamps.

Vision Sensor Reads Linear and Data Matrix Codes

With its Sharpshooter ID vision sensor, Balluff now has an ID version designed to read a large range of linear bar codes and 2D Data Matrix codes, as well as optical character verification (OCV).

The vision sensor can read more than 10 types of linear bar codes, including PDF417 and 2D Data Matrix codes. The Data Matrix code reader reads both printed and direct part mark (DPM) based marks. Since alphanumeric characters like date codes or expiration codes can typically coexist with barcodes, the ID version also has an OCV tool to verify these values.

The Object of Pepperl+Fuchs Newest Photoelectric Sensors is Clear

That is clear object detection. GLV18 Series photoelectric sensors with Clear Object Detection use reflectors to detect transparent objects up to 2.5 m away, or opaque objects up to 5 m away.

Offered in an industry-standard M18 threaded cylindrical housing, the sensor is up to 50% shorter. In addition, the company claims the power consumption is 50% less than many competitive models. 

The sensors can detect clear shrink-wrap webs or semi-transparent trays or cartons in material handling applications as well as the presence detection of clear clamshells, bottles, or pouch webstock in packaging applications.

Photoelectric Sensor Includes Suppression Sensors

Users looking to standardize on a mid-sized block style photoelectric sensor need to search no further than the BOS 23K sensor family from Balluff. Featuring the conventional sensing modes of diffuse, retro-reflective, and thru-beam, the BOS 23K also includes background suppression sensors, thus making it suitable as a “go-to” family for all of your sensing needs.

• Long sensing ranges for extended sensing ability
• Accurate switching performance for precise positioning tasks
• Highly visible red light for easy alignment
• At-a-glance status indication LEDs, viewable from all sides
• Two mounting options – holes or dovetail – for flexible sensor placement
• Impact-resistant ABS housing with rotating connector suitable for many applications

Ideal for use in material handling and conveying applications, the BOS 23K photoelectric block sensor provides a great combination of high accuracy and long sensing range at a reasonable price. In a typical application for example, two BOS 23K diffuse sensors with background suppression are able to monitor different colored totes as they travel from one production station to another without false triggering on the background.

OG Series Photoelectric Sensors from ifm efector

EXTON, PA – ifm efector inc. introduces the new OG Series photoelectric sensors for washdown applications. The industry standard 18 mm diameter housings are 316 stainless steel and designed for food and beverage applications.

The OG’s zero-leak design prevents ingress during high pressure cleaning and steam cleaning. The Ecolab-certified sensors are chemically compatible with industrial caustic and acid solutions and are resistant to chemicals used in washdown environments.

The sensors are fitted with a plastic lens – rather than a traditional glass lens – that eliminates the possibility of glass splintering in food and beverage processes. The OG sensors feature a visible red light source that simplifies installation and maintenance. For application versatility, ifm offers high grade stainless steel mounting accessories for quick mounting.

The Micro DC units are available in a variety of models including diffuse reflective with background suppression, retro-reflective, and thru-beam pairs. Each model offers a light-on or dark-on outputs option.

Non-Contact Photoelectric Level Sensors

Southington, Conn. – For a range of liquid level detection applications in laboratory automation, medical devices, pharmaceutical packaging, beverage processing and other industries, Baumer has introduced the FFDK 16 Photoelectric Level Sensors, compact sensors designed to be mounted onto transparent or half-transparent standpipes from 3 to 13 mm in diameter.

These easy to mount, non-contact sensors feature integrated electronics and require no adjustments to be made post-installation for accurate detection of fluid presence. A dark/light switch allows the user to select the appropriate setting for their specific application. These rugged sensors are made with PFI for chemical resistance.

Foam can cause measurement errors in standard optical level sensors. To prevent this problem, the optical version of the FFDK 16 sensor features fibers that are arranged in rows, which allow the sensor to suppress foam and air bubbles up to 3 mm in size.

Long Range Diffuse Photoelectric Sensor

Buffalo Grove, IL – Carlo Gavazzi launches a new long range diffuse photoelectric sensor with background suppression technology. The new PD112 will detect black objects at distances up to 2 meters, and white and grey objects at up to 2.5 meters. Using triangulation technology, the PD112 can be easily and precisely adjusted, with a 28 turn potentiometer. The user can fine tune the sensor to detect the target at the desired distance, while completely ignoring reflective objects only millimeters beyond.

The PD112 is packed with features that make it simple to use, and highly versatile. Each model has both NPN and PNP output, which is automatically detected by the sensor when wired. Normally open or normally closed output can be selected via a dip switch. Two adjustable timers (1 – 16 seconds) for ON and OFF delay allow for a customized solution.

A truly innovative feature of the PD112 is the mode operation selection. The sensor can be operated in a traditional industrial mode, which is ideal for applications such as material handling, packaging and wrapping, and wood processing. By making a simple dip switch selection, the PD112 can also be operated in a door mode, which automatically optimizes the performance of the sensor for detecting people and objects around automatic doors. This mode allows the sensor to be remotely tested by a door controller, making the sensor compliant with door industry safety standards.

Series 4050 Photoelectric sensors with highly effective background suppression

New Contrinex Series 4050 photoelectric sensors with considerably improved background suppression are built into a 40 x 50 x 15 mm housing and excel by their long operating distance of 500 mm, with a setting range from 20 to 500 mm.

The operating distance is independent of the target color, shape or surface structure, and is set by means of a 3-turn potentiometer with position indication. The devices feature a switching frequency of 500 Hz and work with red light, which considerably simplifies their alignment.

Their outstanding optical characteristics result in a quasi-linear output function with a virtually negligible blind zone (< 1 mm at s = 300 mm).

The sensors are enclosed in a glass-fiber-reinforced PBTP housing, complying with insulation class II. They are equipped with a glass window and a connector that may be adjusted from 0 to 90°. In addition to conventional mounting methods such as mounting brackets, dovetail fastening provides an alternative option.

CONTRINEX has manufactured inductive and photoelectric proximity switches since 1972. It specializes exclusively in the development, manufacture and sales of positioning sensors for industrial use. All departments and management levels in the company’s management system are ISO 9001:2000 certified.
