O200.EL-PV1T.72NV/FREC_H006 is the receiver half of a Baumer O200 miniature through-beam pair, working with a pulsed red laser emitter over a 6 m nominal range. Sensitivity is set with qTeach - a ferromagnetic tool held against the housing instead of a potentiometer - so once the machine runs there is no adjustment on the sensor for anyone to turn.

• Range: actual 5 m, nominal 6 m; smallest detectable object 3 mm (0.5 mm with aperture)
• Output: PNP complementary, light/dark operate, 50 mA
• Supply: 10...30 VDC, typ. 10 mA at 24 VDC
• Response time: < 0.1 ms, jitter < 0.03 ms
• Housing: rectangular 8 x 25.1 x 14.1 mm, ASA plastic, PMMA optics, M3 stainless steel threaded sleeves
• Environment: IP 67, -25...+50 °C
• Connection: M8 4-pin flylead connector, 200 mm

Typical positions are counting and presence checks on packaging and assembly lines, where the aperture accessory brings 0.5 mm parts and gaps within reach. A flashing output indicator reports weak signal margin or a soiled lens, so alignment is checked without instruments. Reciprocal influence is suppressed, so several pairs can work side by side.

O200.TL-GZZY.72NV/FIN2_H006 is the emitter half of a Baumer O200 miniature through-beam pair, with a parallel red laser beam rather than a diverging one, so detection stays even across the whole 6 m nominal range. The emitter diode is switched off either through the test input or over IO-Link, letting a controller verify the receiver channel without anyone breaking the beam by hand.

• Range: actual 5 m, nominal 6 m; parallel beam
• Light source: pulsed red laser diode, 680 nm, laser class 1
• Communication: IO-Link V1.1, port class A, 230.4 kBaud, cycle ≥ 0.6 ms
• Supply: 10...30 VDC, typ. 10 mA at 24 VDC
• Housing: rectangular 8 x 25.1 x 15.8 mm, ASA plastic, PMMA optics, M3 stainless steel threaded sleeves
• Environment: IP 67, -20...+50 °C
• Connection: M8 4-pin flylead connector, 200 mm

A parallel beam pays off where the pair sits at an awkward distance or the object passes close to one side: the spot does not grow with range, so the smallest detectable object and the alignment tolerance are the same at 0.5 m as at 5 m. The emitter is used with an O200 through-beam receiver, which carries the switching output - the emitter has none of its own.
