Magnetoresistive speed sensing, wiring, target setup, basic checks and source-stated intrinsic-safety parameters.

The high-level output is printed as U~0.7 using an ambiguous range-like symbol; its intended expression is not confirmed. The explosion-protection marking's typography is also unresolved. The technical table requires gear module m ≥ 1, while an installation example says modules 0.5–2 can be used. Confirm the target and certification details for the supplied sensor.
Measurement principle and target
YD62 uses a magnetoresistive detecting element with signal processing and a protected rectangular-wave voltage output. It detects ferromagnetic targets and is intended for low-speed through high-frequency speed sensing, including zero-speed capability described in the source.
The source describes use in place of a Hall switch, but its own principle is magnetoresistive. Replacement suitability depends on the supply, output, target and mounting configuration.

Supply-polarity and output-short-circuit protection are listed. The high-level expression is unresolved, as noted above.
Wire and mount the sensor
The wire-color schedule is brown for +24 V DC, black for COM and blue for signal output. The source explicitly says the labels on the physical device take precedence. Match the connection to those labels and verify there is no open circuit or short circuit.
The installation procedure sets a 1 mm clearance between the sensor head and the gear, then tightens the sensor. The stated orientation places the line between the sensor's tail and cable root perpendicular to the gear plane; obtain the configuration-specific drawing to identify that orientation correctly.
One example gear has 99.3 mm outside diameter, 60 teeth and module 1.57. The source says this is an example, not a mandatory gear. For a slotted target, the stated minimum slot width is 4 mm and depth is 3 mm; the stated minimum hole diameter is 5 mm. Gear-module applicability differs between the table and narrative and requires confirmation.
Functional checks and fault handling
Before fitting the sensor into the speed-measurement end cover, move a ferromagnetic piece into contact with and away from the sensor head. A change between high and low output levels is the source's normal-response check.
The source identifies an output stuck high or low during normal operation as a failed-sensor symptom. Because output also depends on wiring, target and clearance, establish the specified installation conditions before relying on that interpretation. If external force damages the lead, the documented remedy is sensor replacement.
Intrinsic-safety installation requirements in the source
The stated entity parameters are Ui = 28 V DC, Ii = 93 mA, Pi = 0.65 W, Ci = 0.3 µF and Li = 0 mH. The sensor/barrier wiring conditions are Uo ≤ Ui, Io ≤ Ii, Po ≤ Pi, Cc ≤ Co − Ci and Lc ≤ Lo − Li. The source prefers an isolated safety barrier and requires a barrier with an explosion-protection certificate, installed and wired to its own instructions.
The source cites GB3836.1-2010, GB3836.4-2010 and GB3836.15-2000, and adds a supply-transformer requirement referencing clause 8.1 of GB3836.4-2010 for Zone 0 use. These are the editions cited by this document, not a confirmation of present regulatory acceptance.
Do not replace internal components or alter the structure, because that can affect protection. Avoid friction or impact on the housing that could produce sparks during use and maintenance.
Ordering configuration
YD62-A-B-C-D uses thread codes A01 = M10 × 1, A02 = M16 × 1, A03 = M12 × 1, A04 = M30 × 2, A05 = 3/8–24 and A06 = custom. Body-length examples are B50 = 50 mm, B80 = 80 mm and B120 = 120 mm. C00 is direct cable, K denotes armor and C01 is a circular connector. Cable examples run from D01 = 1 m and D02 = 2 m to D09 = 9 m.
