Title:
MULTIPLE OPTICAL AXIS PHOTOELECTRIC SENSOR
Document Type and Number:
Japanese Patent JP2018010789
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a multiple optical axis photoelectric sensor capable of stably sealing the insides of a light projector and a light receiver.SOLUTION: A light projector 10 and a light receiver 20 comprise a case body 3, a translucent plate 4 blocking an opening 39 on a front surface of the case body 3, and a pair of caps 5 blocking openings 38 on both end surfaces of the case body 3. The case body 3 comprises a pair of first support parts 35 supporting both side edges of the translucent plate 4. Each cap 5 comprises a second support part 53 supporting both end portions of the translucent plate 4. The translucent plate 4 is supported by both first support parts 35 and both second support parts 53 via an elastic member 8. Each cap 5 is fixed to the case body 3 via a seal member 7 abutting on an end surface of the case body 3. A cured liquid sealant 14 is interposed between both tips of the seal member 7 and the elastic member 8.SELECTED DRAWING: Figure 6
