This document introduces Panasonic's opto-electronic switch products. The product features are small size, small light beam diameter, and different switching distances can be selected according to needs. It is suitable for embedded installation.
The LTK-0507-30# is a miniature reflective light sensor with lateral light emission and a cylindrical light beam of less than 4 mm. It is housed in a stainless‑steel V2A enclosure, features sapphire optical parts, and is fully vacuum‑potted with an IP67 protection rating, allowing recessed mounting.
The sensor measures only 5 × 7 mm in cross‑section and 40 mm in length. It operates from 10 … 30 VDC, delivers 100 mA output current, and includes short‑circuit, polarity‑reversal, and induction protection. Electrical characteristics such as switching frequency (<250 Hz), switching time (2.5 ms), and temperature range (0 … +55 °C) are also listed.
