Abstract: A signal processor for a sensor includes an enclosure and a cable holder disposed in the enclosure and having a first through hole and a second through hole contiguous to the first through hole. The cable holder is moved when a lever is manipulated. A first terminal is disposed in the enclosure so as to intersect at a right angle to the first through hole and a second terminal is disposed in the enclosure so as to intersect at a right angle to the second through hole. A coaxial cable for connecting between the signal processor and the sensor is inserted into the first and second through holes in turn in the state that an exposed shield wire is folded up along an outer insulating sheath of the cable. When the cable holder is moved upon manipulation of the lever, the first terminal is moved into the first through hole, coming into contact with the exposed shield wire.

Abstract: A photoelectric switch includes a light emitting section emitting pulse light so that intensity of the emitted pulse light is sequentially increased. A light detecting section detects the pulse light emitted by the light emitting section. A light detection signal indicative of the received light is amplified and then integrated. A high-level light detection signal is delivered by the light detecting section when an integral value is equal to or above a threshold. A determination circuit delivers a first detection signal when a duration of the light detection signal is equal or above a predetermined values. The determination circuit further delivers a stable operation signal when a set time period is reached. The light detecting section is integrated into one-chip configuration.

Abstract: An electrical connector for interconnecting parallel multiconductor cables includes a housing having a first cable receiving section for receiving a parallel multiconductor main cable and a second cable receiving section for receiving a parallel multiconductor branch cable respectively. Contact members each extend through the housing and have terminal portions projecting from the first and second cable receiving sections so that the main and branch cables are press fitted into the terminal portions. A pair of covers are attached to the housing and each have cable receiving sections pressing the main and branch cables against the first and second cable receiving sections respectively in the condition that the covers are attached to the housing. The housing is engaged with each cover in a state that each cover has been attached to the housing.
