Armament Any 60, 81 or 120 mm mortar bomb with standard fuze wells. Development Jointly by Junghans Feinwerktechnik and Noptel Oy to provide a new countermeasure resistant proximity fuze. Description The PX581 proximity fuze is independent of calibre and can be mounted on any 60, 81 or 120 mm bomb without adjustment. Because it is optronic, there are no known countermeasures. The PX581 is specifically intended for bursting at low altitudes to provide optimal terminal effects. Operating power is obtained through a
windwheel generator that also provides a secondary arming function. The PX581 has a point detonating backup function. Optics are hermetically sealed and protected from temperature fluctuations to prevent accumulation of condensation. The fuze recognises ground surface, but does not react to clouds, mist, snow or rain. The fuze uses laser based ranging technology and sends out light pulses at the rate of 500 per second while the receiver constantly measures the distance to the target. The `smart' fuze recognises the target and detonates the bomb at the pre-programmed height with an accuracy of ±1 m. The fuze is fully compliant with MIL-STD-1316D, MIL-STD-331B, STANAG 4157 and STANAG 2916. There are both mechanical and electronic safety measures. A double bolt system and the windwheel assure mechanical compliance while the MIL-STD-1316A sensor electronically secures the fuze until it reaches its trajectory apex. Operating temperature range is from -40º to +60ºC exposed and from -55º to +71ºC in packaging.
