Holmberg at Paris air show
The 50 th Paris air show will take place at Le Bourget airport from 17 to 23 June 2013.
Of course, Holmberg is again one of the exhibitors. We would be pleased to welcome you at our booth. We will be there in hall 4, booth E30.
Au revoir à Paris!
New Handset Series N-40
The new N40 handset has been developed primarily for aviation applications. It’s already used in the new Airbus A380. On the basis of this device, a new series of handsets has been created, which has benefited from the experience in aviation.
The N-40SR (picture left) is designed for mobile use, in particular for railway and emergency services. The generous PTT button is easy to reach. When not in use, the handset remains securely in the cradle - even when the vehicle accelerates sharply – thanks to a firm retaining mechanism.
With its unobtrusive PTT button, the N-40R (picture centre) is intended primarily for control centres.
The N-40N handset (picture right) is designed for installing in roadside emergency phone units. A special cradle for vertical installation has been developed for this use, ensuring the unit has a very low profile even with the handset in place. This means that the N-40N can fit even in shallow enclosures.
The N-40 USB handset connects directly to the USB port of your computer. It is plug-and-play compatible.
The N-40 handset series combines a hard-wearing mechanical design with outstanding acoustic and electrical properties. The excellent RFI/EMI immunity is a particular feature. The N-40 is housed in a rugged, high-impact plastic body. The housing and connecting lead are made of halogen-free, flame-retardant and self-extinguishing plastic rated UL-94 V-0. The flexible design of the new handset means that it can be customised precisely to specific project requirements. A choice of cradles makes it easier to find the right model for the given conditions.

New PTT-Button ASP-23
The lightweight inline push button ASP-23 has a length of only 57 mm. It has 2 cable inlets for cable diameters up to 5 mm and can easily be integrated into connection cables of headsets. The press-to-talk key can be loaded with 24 V/50 mA. The shock-proof plastic housing is self-extinguishing acc. to UL 94 V-0.

Headsets for extremely low temperatures
Freezing and icy conditions are a challenge for man and materials. Conventional headsets often reach their limits in these conditions. The main problem is that moisture in the breath condenses on the microphone and then freezes. It forms a layer of ice which progressively closes up the holes in the microphone, making any communication impossible.
Holmberg has developed a new microphone voice pick-up for this situation, which instead of an airborne-sound microphone uses a sensor for detecting structure-borne sound. This piezoceramic sensor is waterproof (IP68) and tolerates extremely low temperatures. It enables reliable and good-quality speech transmission in bitterly cold conditions, even when the microphone is covered by a layer of ice.
The HD-82-P and HD-84-P headsets are based on established models which have been developed to work with this new structure-borne sound sensor. Both headsets can be used at extremely low temperatures down to -60 °C (-76 °F)and work even with an iced-up microphone.
The HD-82-P headset ear-defenders are designed for use in noisy environments. The ear cups provide excellent noise attenuation, protecting the wearer from unwanted background sounds. The HD-82-P headset is splash-proof (IP54) and suitable for outdoor use.
The HD-84-P headset can be worn comfortably under a hood. The dynamic earpiece capsules are housed in lightweight ear cups that muffle background noise without isolating the wearer entirely from their surroundings. Thanks to its lightweight design, the headset is also suitable for prolonged use. It is already being used successfully in refrigerated warehouses.
Washable cotton covers are available for both headset models as hygiene protection. The headsets are each supplied with a coiled cable and LEMO plug as standard and are electrically compatible with numerous other Holmberg headsets. An extensive range of adapter cables with built-in PTT button are available for connecting to different radios.
