Photoelectric sensor | through-beam type | transmitter + receiver | 20m | M18 | 10-30VDC | NO/NC | PNP | 2m cable | ABS housing | infrared beam | IP67
Code: PSS-TM20DPBPhotoelectric sensors – high-quality through-beam type sensors designed for long-distance object detection. The system consists of two parts – a transmitter and a receiver – which create an invisible infrared beam. When an object passes between them and interrupts the beam, the receiver detects the change and sends a signal to the control system.
They are characterized by exceptional accuracy, high resistance to environmental factors (IP67), and are suitable for industrial production lines.

Indicators: Green LED – power/stable operation; Yellow LED – output signal, short-circuit or overload indicationMain Features:
The sensors operate on a through-beam principle – the transmitter emits a light beam, and the receiver detects its interruption. This allows precise object detection even in dusty or noisy environments.
The robust housing ensures reliable mounting and durability, while IP67 protection allows operation in humid and dusty conditions.
The system is stable, fast-reacting, and energy-efficient, making it suitable for automation, safety, transport, and household applications.Usage and Applications:
For home users: Suitable for object detection in workshops or small automation projects.
For engineers/automation specialists: Ideal for robotics, production line object detection, conveyor control, positioning, or packaging inspection.
For electricians/technicians: Easily connectable to PLCs, relays, or direct automation systems. IP67 protection ensures safe use in damp or dusty environments.Pros:
Fast response
IP67 dust and water resistance
Durable housing
Clear LED indicators
Easy installation and integration with automation systems
Cons:
Non-adjustable detection range
Not suitable for very small or transparent objects
