The Wenglor SN6003 Through Beam Sensor operates as the emitting half of a dual-component sensing system. By utilizing a separate emitter and receiver configuration, this through-beam technology provides the highest possible resistance to environmental interference. Unlike standard reflex sensors, the SN6003 maintains its signal integrity even in the presence of dust, steam, or ambient light, making it a reliable choice for challenging industrial settings.
With a massive 60-meter operating range and a high switching frequency of 2,000 Hz, this sensor is built to handle high-speed production lines without missing a beat. The integration of an RS-232 interface allows for sophisticated parameterization, enabling users to activate and configure on/off delays (0 to 5 seconds) to smooth out signal processing and prevent false triggers. The unit is fully encapsulated in a durable housing made from PBT and V2A stainless steel, boasting an IP67 rating that ensures complete protection against dust and water ingress.

Technology that moves in over three decades of wenglor sensoric. On this interactive journey through time, we researched deep into wenglor’s archives and have tracked the history of the company since the eighties – starting in an attic and growing into a global corporation.
