Azbil Model FL2-_ _ _ _ D.C. 3-Wire Square Proximity Sensors can directly switch relays and solenoids with a maximum switching current of 200 mA. A wide variety of models are available, including 4, 7, 12, and 20 mm sizes, top or side sensing, and N.O. or N.C. operations modes. The sensors have a high seal, IP67. Enhanced circuit protection is built in for surge absorption, load short-circuit and reverse connection. Different-frequency types that are only slightly influenced by mutual interference are available for all models. The sensors have enhanced circuit protection, including surge absorption, load short circuit, and reverse connection countermeasures. Sensing distance 4mm to 20 mm depending on the size. Standard (pre-loaded) model dimensions (mm) – Switch package style: 12 x 12 x 45, 15 x 15 x 32, 20 x 20 x 38, 30 x 30 x 52.5, 40 x 40 x 53. Cord length is 1 m.
