Wenglor OSII403Z0103 Through Beam Sensor | 50m Range Emitter

Description

The Wenglor OSII403Z0103 Through Beam Sensor serves as the high-intensity light source in a through-beam system. By projecting a powerful red light beam to a compatible receiver, it establishes a reliable barrier for presence and position control across distances that standard sensors cannot reach. This long-range capability is supported by a large switching reserve, which enables the light beam to effectively penetrate environmental contaminants such as dust, steam, or fog.

A key technical advantage of this model is the integrated test input. This feature allows the transmitter to be deactivated via a control signal, enabling the connected system to verify that the receiver responds correctly. This proactive diagnostic tool significantly reduces the risk of undetected sensor failures in critical processes. Furthermore, the unit is designed for durability, utilizing an ABS/GF plastic housing that resists impact and chemical exposure. With an opening angle of 5 degrees, it provides a balance between ease of alignment and focused beam intensity, ensuring precision over its entire 50-meter range.
