SUNSTAR photoelectric switch, model 604-06-034-01-R, wire diameter Ø3.0mm, with 3 mounting holes, mounting hole spacing 34.4mm, sensing distance 42.5mm, product size 27.7mm*41.2mm*10.5mm, product weight 3.0g.
The 3ND nitrogen dioxide CiTiceL from City Technology is a compact gas sensor designed for air monitoring. It offers a nominal detection range of 0‑100 ppm with a maximum overload of 1000 ppm and is rated for two years of operation in air.
Key performance data include a response time under 35 seconds, a temperature range of roughly –20 °C to 50 °C, and a pressure coefficient of 0.037 %/mBar. The sensor can be ordered with side tags, gold‑plated PCB pins, or both, and is supplied with a 33 Ω recommended load resistor. Warranty is 12 months from shipment.
