NPN open-collector output switches up to 50 mA on 12 to 24 V DC. Teach-in function sets light- or dark-on thresholds on the fly. Response time under 200 µs keeps up with fast-moving parts on packaging or pick-and-place lines. Rated IP50, housed in PBT, and sized at 64.3 × 31.5 × 10 mm for DIN-rail mounting in a control cabinet. The fixed 2 m lead terminates in bare wire; no connector options are available from this order code.","metaTitle":"Omron E3X-SD21 2M Fiber Amplifier, NPN, <200µs","metaDescription":"Omron E3X-SD21 2M simple fiber amplifier unit, NPN output, 12–24V DC, response <200µs, IP50, 2m lead.
