SICK ISD400-7312 Photoelectric Sensor Through-Beam

The ISD400-7312 optical data transmission system from SICK (part number 1071579) is a through-beam data link that transmits optical data between two devices across line-of-sight distances from 0.2 m to 200 m, using a red 660 nm laser. Housed in an AlSi12 enclosure with IP65 protection and weighing approximately 800 g (unloaded at 24 V), it is designed for rugged industrial environments. It operates on 18–30 V DC with a maximum power consumption of 3.6 W and provides a data interface via an Ethernet-style M12 4‑pin D-coded connector, while power is supplied through an M12 4‑pin A-coded connector. Data transmission requires two devices to complete the link, reflecting its role as a paired optical data transfer system. The unit supports ambient temperatures from –20 °C to +55 °C and up to 90% relative humidity (non-condensing), making it suitable for demanding factory settings. Safety notes accompany the product, including the directive to avoid staring into the 660 nm laser beam and to align the beam properly for reliable operation.
