Lanbao PSBT-TM3DNO-E1 3mt Detection, Output NPN NO, Rectangular Through-Beam Photoelectric Sensor

Lanbao PSBT-TM3DNO-E1 3mt Detection, Output NPN NO, Rectangular Through-Beam Photoelectric Sensor, is a Lanbao-brand product in the rectangular photoelectric sensors category. Product code is PSBT-TM3DNO-E1. Lanbao PSBT-TM3DNO-E1 3 m Detection, Output NPN NO, Rectangular Through-Beam Photoelectric Sensor Lanbao PSBT-TM3DNO-E1 is a through-beam photoelectric sensor set with a rectangular optical design that can detect objects passing through a light path of up to 3 meters. The sensor consists of two parts, a transmitter and a receiver; the output signal stays active as long as the light path remains open. When the light path is interrupted by an object, the sensor sends a switching signal to PLC or DC control systems, producing only an NO (Normally Open) contact signal with an NPN logic output. This construction provides a reliable optical signal in short-distance conveyor lines, machine cycle controls and panel digital input triggering. The prismatic optical design transmits light at a wider angle and more strongly, which increases signal stability in short-range detection and reduces false triggering. The through-beam architecture does not require an external reflector, which simplifies sensor installation and optical alignment processes. The DC wired connection allows direct connection to control systems, providing the advantages of fast commissioning and low maintenance.

The reflector-free design simplifies sensor installation and optical alignment. The NPN NO output provides a clear logic signal in PLCs or other control systems. An approximately 1 kHz switching speed enables fast response and stable signal generation. The 10–30 V DC cable connection provides direct integration into PLC/DC control systems, and this design forms a reliable optical detection solution that offers quick commissioning, low maintenance and an economical advantage.
