Banner Engineering DF-G3LIR-PS-Q3 Dual Display Fiber Amplifier

The DF-G3LIR-PS-Q3 is Banner Engineering’s dual‑display, long‑range fiber amplifier in the DF‑G3 family, configured for a Long IR beam (1450 nm) water‑detector application and delivering a single PNP discrete output when the beam is interrupted. It accepts 10–30 V DC supply and ships with a 0.15 m (6 in) M8 quick‑disconnect pigtail, all housed in a thermoplastic DIN‑rail enclosure rated IP50 and NEMA 4X for basic environmental protection. The unit accepts Unterminated Plastic Fibers or T5 terminations and its performance range depends on the chosen fiber; the long‑range infrared variant is designed to work with Banner’s fiber options for extended sensing distances. It features dual digital displays for setup and monitoring, remote teach capability, and crosstalk avoidance to improve stability in multi‑beam installations. Key electrical and timing specs include a 10–30 V DC input, a single PNP output, a 500 ms power‑up delay, and a minimum response time of 0.5 ms with 50–250 μs repeatability. Operating conditions span –10 to 55 C and up to 90% relative humidity at 60 C. The quick‑disconnect 4‑pin connector and compact 150 mm cable length simplify installation on DIN rails, while the dual displays provide immediate status and teach data for beam alignment. This amplifier is well suited for industrial fiber sensing tasks where a long‑range 1450 nm beam must reliably trigger a discrete signal, integrating with Banner’s automation ecosystem or compatible controllers.
