New Public Safety Antennas Enable Improved Safety and Security for Emergency Responders and Building Occupants

Global technology leader Laird (LRD: London) introduces two new, in-building, public safety antennas with industry leading frequency performance that ensure more reliable communications and greater connectivity for emergency responders.

Radio communications can be unreliable inside large and small facilities, multi-floor and high-rise office buildings, apartment complexes and public venues. In-building structural, mechanical and electrical generated interference and the many obstructions encountered by emergency personnel moving through the building weakens two-way radio and wireless device signals causing communications to be dropped.

A lack of reliable communication can be dangerous for emergency responders like police, paramedics and firefighters, as well as for the building occupants they are trying to help.

To ensure consistent, highly reliable emergency voice & data radio coverage inside buildings, Laird engineers have designed a range of new antennas for a Distributed Antenna System (DAS). The Ceiling Mount Single-port (CMS) Standard and CMS Low Passive Intermodulation (PIM) Omnidirectional DAS Antennas deliver superior wide band performance across the 380-960 MHz and 1395-6000 MHz bands including the Advanced Wireless Services (AWS-3) band and LTE 600 MHz band. All of this from one aesthetically pleasing and compact housing built for highly reliable operation in extremely harsh conditions.

“Covering more frequencies within a single antenna means more reliable communications between more types of wireless devices. And reliable communication for all of those radios increases the potential to save more lives,” explains Jack Cowper, Laird’s Senior Vice President of Infrastructure Antenna Systems. “The safety and security of building occupants and emergency first responders who serve and protect our lives and property is of the upmost importance. The CMS line of Public Safety DAS Antennas deliver superior performance, and provide a highly reliable extension of in building emergency wireless communications in the most extreme operating environments,” says Cowper.

Both antennas are IP67 rated for dirt and dust intrusion and temporary water immersion making them ideal for highly reliable operation in harsh indoor and outdoor conditions. Compliant with in-building International Fire Code (IFC) & National  Fire Protection Association (NFPA) regulations the CMS Standard and Low PIM antennas support applications including multi-floor and high rise office buildings, industrial and apartment complexes and public venues.

The CMS Public Safety DAS antennas come standard with an industry leading five (5) year materials and workmanship product warranty.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
