Japanese Patent JPH0527812
Kind Code:
B2
Abstract:
A pyroelectric infra-red radiation detector which is particularly suited to automated assembly comprises a pyroelectric detector element (1) mounted in a housing (4) having a window (5) transparent to infra-red radiation. Electrically conductive leads (6,7,8), e.g. in a single-in-line configuration, extend through a base portion (9) of the housing for making external electrical connections to the detector. Lead (8) comprises an extended portion (8b,8c,8d) within the housing providing a cantilever support (8d) to which the detector element (1) is fastened. The leads (6,7,8) may all be formed from portions of a unitary lead frame. A second differentially connected pyroelectric detector element (2) may be fastened to another cantilever support (16b) formed by a portion of the same lead frame. The cantilever supports (8d,16b) preferably extend from an insulating block (11) which encapsulates an associated electrical component (18) and which also provides support for the detector elements.
