Sensor Laser photoelectric Switch NPN NO + NC Input(10-30VDC), 4 Wires; Detection Distance 8-50cm; HG18-D50N3, 12V; 24V Normally Open and Normally Closed Photoelectric Beam Sensor (NPN, NO+NC)

Description

Product Overview

The LCTC sensor laser photoelectric switch is engineered for high‑precision detection in demanding industrial settings. Featuring an NPN NO+NC configuration with a 4‑wire design, the device provides both normally open and normally closed outputs, giving flexibility for a wide range of control circuits. Its compact dimensions—2.56 x 0.63 x 0.63 inches—and lightweight construction (5.29 ounces) make it easy to integrate into tight spaces. The laser emitter delivers a focused beam that can be adjusted to detect objects from 8 mm up to 50 cm, covering a broad spectrum of applications from small part detection to larger object monitoring. With a rapid 1 ms response time, the switch reacts instantly to changes in the optical path, ensuring timely actuation of downstream equipment. The unit operates on a supply voltage range of 10‑30 VDC, supporting both 12 V and 24 V systems, and includes built‑in short‑circuit and reverse‑polarity protection for added reliability.

Usage

Designed for industrial automation, this laser photoelectric switch excels in environments such as conveyor belts, packaging lines, robotic workcells, and safety barrier systems. Its adjustable detection distance allows users to fine‑tune the sensor for specific object sizes, making it suitable for detecting tiny components on a PCB assembly line or larger items on a bulk handling conveyor. The robust NPN output can directly drive relays, PLC inputs, or motor controllers without additional interfacing hardware. Because the sensor operates with low no‑load current (<30 mA) and a maximum load current of 200 mA, it can be powered from standard industrial power supplies while maintaining energy efficiency. The open‑collector output design also enables easy integration with existing control panels, and the 500 Hz switching frequency ensures smooth operation even in high‑speed applications.
