Optical Sensors - Photointerrupters - Slot Type - Logic Output

The LC-100-PL2000-A-P-PN-J from Panasonic is a slot type logic output photointerrupter designed for applications such as bar code readers, presence or proximity sensing, optical motor control, and positioning. These devices offer high-speed response, high-radiation immunity, and low-power operation.

Application Fields

The LC-100-PL2000-A-P-PN-J is suitable for a broad range of applications including bar code readers, proximity sensing and motor control. The device is compact and easy to install, suitable for many applications in a variety of industries, including electronics, manufacturing and automation, medical, and automotive. The device can also be used with a variety of other Panasonic products, such as the CVP-350-PL2000-A-P-PN-J and the FVE-100-???-A-P-PN-J, in order to provide an integrated solution to many sensing requirements.

Working Principle

The LC-100-PL2000-A-P-PN-J is an optocoupler that uses infrared light to generate a logic output. It has an integrated transistor output that is activated when there is a break in the light beam which is focused onto the detector phototransistor. The device comprises of an infrared light-emitting diode (LED) that operates at 880nm, and it is connected with the detector phototransistor. The LED and phototransistor are packaged in a 2.3mm wide-slot type reflector, which allows a very narrow slit between them. When an object passes through the slit, the light beam is interrupted, which in turn switches the transistor output on. The LED emits a consistent 880nm light that is focused onto the detector phototransistor with a peak sensitivity of ∼850nm in order to ensure a stable response to the interrupting objects.

The device features a wide supply voltage range of 3 to 20V, and a maximum current of 5mA. It can operate at high speeds, up to 300kHz, and is efficient in terms of power consumption, with an operating current of only 13mA when the transistor output is enabled. The device is also immune to disturbances from ambient light sources, with an immunity of up to 1000lux.

The LC-100-PL2000-A-P-PN-J is an excellent choice for applications that require fast response times, high immunity, and low power consumption. This attractive combination of features makes it a great choice for bar code readers, proximity sensing and motor control.
