Product description

The Allen Bradley 42KL-G1TC-A2 is a through-beam photoelectric sensor from the 42KL series, designed for high-reliability object detection over longer distances. This sensor requires a separate emitter and receiver pair, offering robust performance by detecting when the beam between them is interrupted. It features an NPN output for easy integration into automation systems.

Through-beam sensors like the 42KL-G1TC-A2 are ideal for applications requiring maximum sensing range and immunity to surface variations of the target object. They are commonly found in high-speed packaging lines, large-scale material handling, and automated gate systems where precise beam interruption detection is critical.

Stanlo Automation, a veteran-owned surplus industrial parts distributor, understands the importance of reliable components. We offer the Allen Bradley 42KL-G1TC-A2 and other surplus parts, providing cost-effective solutions to ensure your automation processes remain uninterrupted and efficient.
