Armament 81 mm mortars having standard fuze cavities of 2.00-12NS-1. Development By US Army Ordnance. Description The M532 is a radio frequency-type proximity fuze for all 81 mm mortars having standard fuze wells. The proximity element functions over land or water and the fuze will function upon impact if the proximity function fails. The M532 can also be set to disable the proximity function if impact functioning is desired. This is accomplished by turning the nose cap. Once selected, the point detonation
function is irreversible. Arming is initiated by setback forces, which must actuate both an electrical and mechanical system. Airburst over the target is 3.04 to 4.5 m. The fuze consists of a ribbed plastic nose attached to an aluminium ring, which is in turn attached through a slip joint to an aluminium base. A steel housing is screwed into the base. Radio transmitter/detector and amplifier/triggering circuits are contained within the plastic nose. A thermal reserve battery within the base supplies power to the electronic circuits. A setback-initiated arming delay clock, detonator and booster pellet are contained within the steel housing. The nose and attached ring are turned {1/3} turn or more in the direction indicated to change the mode of operation from proximity to impact. It cannot be reset. A shear pin prevents accidental turning during normal handling. Manufacturer US government contractors.
