Introduction:
- Lorentzzi® M18 photoelectric sensor is available in three types: diffuse, retro-reflective, and through-beam. The maximum detection distances are 30 cm, 2 meters, and 5 meters, respectively.
- The one will be introducing here is a diffuse proximity sensor switch with a diameter of 18 mm thread size that uses 660 nm infrared light to detect the presence of any object, whether it is metallic or non-metallic.
- The output can be selected in three modes: solid-state NPN normally open (NO), solid-state PNP normally open (NO), or two-wire normally open (2-wire NO), corresponding to the models G18-3A30NA (or E3F-DS30C4), G18-3A30PA (or E3F-DS30P1), and G18-3A30LA (or E3F-DS30Y1), respectively. Alternatively, the output can also be selected in normally closed (NC) mode.
- The knob at the rear of the photoelectric sensor allows for adjustment of the detection distance, ranging from 10.0 cm to a maximum of 30.0 cm.
- This M18 diffuse photoelectric sensor uses Light-on to detect objects. “Light-on” means that the receiver needs to receive light from the transmitter before it can activate the output.
- Default working voltage is 6-36VDC, other voltages can be customized as well.
- Two housing materials are available: ABS plastic or nickel-plated brass.
- Note: This M18 photoelectric sensor should be used in a clean environment, away from dust and oil, and requires regular maintenance.
- For more information on our M18 diffuse, retro-reflective, or through-beam photoelectric sensors, please see the parameter table at the bottom.
Application:
- Object counting in packaging, labeling, and textile manufacturing;
- Object positioning in conveyor belt material handling;
- Liquid level detection in food and beverage processing;
- And other applications.
