MV-LC0017 650 kg Load Pin with M24 Retaining End

METRAVON MV-LC0017 is a compact load pin with a 650 kg technical reference, an M24 retaining-end callout and an axial cable outlet. It belongs to a much smaller load class than the tonne-rated pins in the same catalogue. For a small joint, the enquiry should identify the actual force carried by the pin, the bearing fits and how the end is retained. A threaded end does not turn it into a bolt-type tension sensor.

Check the 650 kg load pin against the actual joint force

Keep the rated unit explicit: the technical entry is in kilograms, not tonnes. The pin reaction can differ from a carried mass because of the mechanism geometry and force directions. Provide the joint section and operating positions rather than just a machine payload. Define the useful changes that the control system must recognise. The 0.5% FS precision entry and 0.5% FS per 10 deg C temperature effect are full-scale references, so a small indicated change should be assessed against that basis and the actual reader.

Use the retaining thread without changing the bearing condition

The outline shows M24 at the end, three diameter-24 lands with negative tolerances, a 175 mm longitudinal reference, an 84 mm inner reference and a diameter-6.3 through-hole near the retaining end. A diameter-40 end feature and further local dimensions are also shown. Obtain the controlled drawing for thread pitch, engagement, bore fit and the functions of the retaining features. Do not move a nut or spacer against an unintended shoulder so that it changes the support condition or forces the sensor to act as an axial tie.

Reserve cable access when the pin is inserted and removed

The cable exits along the pin axis at the opposite end to the retaining detail. Show the available axial space, gland clearance and route to the junction or reader. Retention should preserve the intended measurement orientation without twisting or pinching that cable. If the joint requires a different exit direction, obtain an approved mechanical and electrical configuration rather than bending the gland or modifying the pin. Any removal procedure needs a safe way to support the connected members before the sensing pin is released.

Keep the optional amplifier separate from the bridge specification

The detailed channel is a 1.0 +/-0.015 mV/V bridge excited at 10-12 V DC. The feature text mentions an optional built-in 4-20 mA amplifier, but it does not settle every supply and wiring detail for that option. Ask the quotation to identify whether the delivered item is bridge-only or amplified, with its supply, scaling and cable functions. Do not apply a process-transmitter supply to the bridge by assumption. The bridge colour list and circuit disagree on signal polarity, so use the delivered connection record and a controlled loading check.

Accept the small joint in its final retained condition

Use agreed reference loads through the actual joint, comparing loaded response and unloading return after the retention is secured. If adjustment of a spacer, nut or cable restraint changes the reading, investigate the mechanical cause before changing calibration. IP67 and material choice need comparison with actual cleaning, water and corrosion conditions; the operating interval is -40 to +85 deg C. A 200% FS safe-load entry is not a test instruction for the linkage or permission to use the retaining thread as an unsupported lifting attachment.

For MV-LC0017, send the 650 kg-class joint section, worst pin reaction, M24 retention detail, cable access and intended reader.
