Abstract: There is provided a photoelectric switch in which a beam reflected by an object to be detected is received in a trigonometric manner so that any failure in the distance measurement of the object can be prevented with employment of ordinary amplification circuit for received-light signals without enlarging the figure of the dynamic range of the circuit. In the switch, a circuit for comparing the ratio of the received-light signals to a predetermined operational level includes means for setting the nearest limit point for a set range of a detecting area to be farther than an intersection of the projected light beam with a line connecting centers of light-receiving lens and received-light detecting element so that the detection of the object can be made even when the dynamic range of the amplification circuit is saturated, whereby the presence of the object in the detecting area can be always discriminated even upon the dynamic range saturation of the amplification circuit.

Abstract: A circuit having an effective output capacitance the value of which can be varied over a predetermined range of values includes first and second differential amplifiers. The differential inputs of the second differential amplifier are connected to the differential outputs of the first differential amplifier, the latter of which receives a variable control signal. The second differential amplifier includes a pair of transistors the emitters of which are AC coupled to ground. A capacitor is coupled between the base and collector of one of the pair of transistors, the collector of which is coupled to the output of the circuit. A diode is AC coupled between the base and ground of the one transistor whereby the impedance thereof is varied in direct relationship to the conduction of the one transistor in response to the control signal thereby causing the value of the output capacitance of the circuit to be varied.
