Optic sensors in threaded sleeve

Sensitivity Zone

The sensitivity zone for reflective sensors is the maximum distance from the sensor face of a measuring card (white cardboard measuring 20x20cm) approached along the light beam axis, at which the sensor's output circuit switches.

Range

The operating range for reflective optical sensors is the maximum distance from the sensor face of a reflective reflector, or for barrier-type sensors, the maximum distance between the transmitter and receiver of the barrier, which ensures correct operation of the sensors when the light rays are interrupted by an object within the range.

Hysteresis

The operation of optical sensors is characterized by the presence of switching hysteresis, which is the difference in the distance between the object and the sensor at which the sensor changes the state of the output circuit.

Coefficients Correction Factors

The amount of reflected light has a significant impact on the optical sensor's operating zone. It depends on the type of material the object is made of, its color, structure, and dimensions. Light surfaces, such as white paper, reflect more strongly than dark surfaces, such as black cardboard. Correction factors for various materials, taking into account the light reflection properties, are given below.

Output function

The sensors' binary contactless outputs enable direct interaction with relays and programmable logic controllers. Optical sensors with PNP switching transistors enable (NO) or disable (NC) the current in the load connected to the sensor output. In the PNP version, the sensors connect a positive potential to the sensor input.

Power supply

TO optical sensors are used in direct current automation systems (10...30V DC). The sensors are characterized by low current consumption from the power supply. The power supply largely determines the correct operation of optical sensors. Optical sensors can be powered by either stabilized or unstabilized DC voltage. When powered by unstabilized voltage, voltage ripple must not exceed 10%.

Residual Voltage

Residual voltage is defined as the voltage drop at the sensor's output when the output is activated.

Output Overload and Short Circuit Protection

Optical sensors powered by DC voltage have current protection that protects the sensors from damage due to short-term and continuous overload or output short circuit. This protection limits the output current and monitors the status of the sensor's output circuit. Once the overload condition is resolved, the sensor automatically switches to operating mode.
