Takex has released the Takex Intelligent Quad PB-IN200HF photoelectric beam, an active infrared photobeam giving line of sight range of 200 metres externally and a scalable capability that allows cross hatching to any height.

ACCORDING to TAKEX’s Tom Kincade, the PB-IN200HF intelligent photoelectric beam is the company’s flagship product and gives end users and integrators a powerful and affordable tool to handle bigger sites.

 

“The Takex PB-IN200HF is designed to provide line of sight detection with an outdoor range of 200m and an indoor range of 400m,” Kincade explains.

 

“The PB-IN200HF is a completely scalable solution which can offer linear or cross hatch protection over any distance or height.

“It’s immune to white light sources up to 50,000LUX and has extremely high immunity to RFI & EMI. Importantly, the PB-IN200HF carries CE, UL and S.C.E.C. approval.”

 

According to Kincade, the PB-IN200HF benefits from the fact Takex has more than 50 years experience in developing outdoor detection technology.

 

“We know our outdoor PIRs and PE beams provide long and dependable service, even in the most demanding of environments,” he says. “It is for this reason that our outdoor sensor products are specified by police, military and royal institutions across the globe.”

 

While false alarms are often an issue in challenging external environments, Kincade says there are various unique features offered by Takex which combat false alarms.

 

“The first thing is beam strength,” he says. “All TAKEX outdoor photoelectric beams have an arrival distance which is 10x greater than the recommended protection distance, ensuring trouble free operation in a variety of conditions.

 

“Next there double pulse modulation. Our unique coupling of a double pulse modulated signal transmitted to a receiver with a phase lock loop circuit ensures that beams will effectively ignore any form of interference by way of bright light or IR flooding.

 

“This technology also allows the TAKEX product to perform even when there is only 2 per cent reception of Infrared signal.”

 

According to Kincade, like other Takex beams, the PB-IN200HF is AND gated and this helps prevent false alarms caused by falling leaves, birds and debris.

 

“We also have automatic gain control – the PB-IN200HF automatically adjusts the sensitivity margin during poor weather conditions,” he says.

 

“And it’s fitted with an output which will trigger when the reception at the receiver drops below 20 per cent. This feature provides early warning that the sensor is becoming covered in snow, ice or is being subject to extreme weather conditions. This output also serves as a warning that grass or branches are growing in the path of the sensor.

A hot topic at the moment is video verification and Kincade says Takex takes this into account.

 

“TAKEX manufactures camera housings which can be fitted on the tops of our beam towers to allow for video verification requirements,” he explains. “We offer bespoke protection for any situation. If video verification is required, our range of products will fit into any application.” 

 

In terms of new releases, Kincade says TAKEX will be releasing a new range of improved photoelectric beams called the PXB range in the near future.

 

“The PXB range is modelled off the benchmark PB-IN200HF,” he says. “The improvements are IP65 rating, with unique fabric venting system, high Contrast internal casings for easy identification of TX and RX units from 200m or more, improved visual sight (Aiming tool), and increased up & down aiming to -+20°.

 

“It also has wireless, an automatic alignment tool, allowing for effortless one man installation, a widened beam pitch and beam width to drastically reduce any risk of false alarms caused by falling braches, large birds or snow,” says Kincade.

 

“The new unit will also have super low current consumption of only 34mA for the 200m version.”
