Lanbao PSBT-TM30DNO 3mt Detection, Output NPN NO, Diameter Prismatic Through-Beam Photoelectric Sensor

Lanbao PSBT-TM30DNO 3mt Detection, Output NPN NO, Diameter Prismatic Through-Beam Photoelectric Sensor, is a Lanbao-brand product in the prismatic photoelectric sensors category. Product code is PSBT-TM30DNO. Lanbao PSBT-TM30DNO 3 m Detection, Output NPN NO, Diameter Prismatic Through-Beam Photoelectric Sensor Lanbao PSBT-TM30DNO is a through-beam photoelectric sensor set with a prismatic optical design that reliably detects objects passing through a light path of up to 3 meters. In this model, the transmitter and receiver sensors are placed facing each other; the output signal is active as long as the light path remains open, and when the light path is interrupted by an object, the sensor sends a switching signal to PLC or DC control systems by producing only an NO (normally open) output signal with NPN logic. This construction provides fast and clear optical feedback in short-distance conveyor lines, machine cycle controls and panel digital input triggering. The prismatic optical design transmits light to the opposite side at a wider angle and more strongly, which increases signal stability in short-range detection and reduces false triggering. Thanks to the through-beam architecture, no external reflector is required, 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.

Since no reflector is needed, sensor installation and optical alignment are simplified. The NPN NO output provides a clear logic signal in PLCs or other DC control systems. An approximately 1 kHz switching speed enables fast response and stable signal generation. With the 10–30 V DC cable connection, the sensor can be commissioned quickly and offers an economical optical detection solution with low maintenance.
