MV-LC0019 Load Pin with Connector-End Housing, up to 250 t

METRAVON MV-LC0019 is a load pin with a connector-end housing and a technical reference up to 250 t. Its electrical build and connector arrangement should be identified at the same time as the joint geometry. A cable that mates mechanically is not proof of compatible power or signal assignments. For an instrumented heavy joint, request one confirmed mechanical drawing and connection schedule for the actual supplied version.

Specify the load pin output before choosing the controller channel

The reference lists a 1.0 +/-0.015 mV/V bridge, a 4-20 mA/24 V DC route and CANopen or CANopen Safety options. Do not order a generic signal list and leave the hardware choice until installation. State what the receiving PLC, RTU or local load display can actually read. Confirm supply, scaling, number of channels and any external conditioner. A current or CAN version must not inherit the bridge 10-12 V DC entry without a build-specific electrical schedule.

Obtain the connector view and pin assignment for that same build

The reference contains a four-position connector legend and an amplifier sketch, but their signal-colour descriptions are not consistent. They are not a universal pinout for bridge, current and bus configurations. Ask for connector designation, mating-face orientation, keying, terminal functions and the required cable assembly. Do not wire a terminal marked ground as protective earth without its defined function. Confirm the sealing condition with plugs fitted and the treatment of any unused connection, rather than deriving IP67 performance from the unmated connector appearance.

Leave room for the end housing without moving the supports

The mechanical outline carries a diameter-120 reference, a 170 mm longitudinal datum and a further 32 mm end section. It shows the F load position and two support symbols in a specific arrangement. Do not treat the whole end housing as an additional bearing surface or shift a bush onto it to make a short joint fit. Provide the joint member widths, support positions, retention, connector access and expected movement for review. The rated drawing must establish which surfaces carry force and which only enclose the electronics or connection.

Define channel checking without assuming a certified safety function

If the project needs more than one measurement channel, obtain the delivered channel definition, independence information, scaling and fault reporting. Agree how the controller should detect a lost or implausible measurement, based on those documented functions. The general redundant-output description and a CANopen Safety option name do not establish a complete certified protective function. Any safety use needs the actual option documentation and validation of the entire system; no safety level or certification is promised by the mechanical pin rating.

Verify the joint and the received signal together

Apply agreed reference loads through the final installed joint and compare the physical load reference with the controller indication, repeat response and unloading return. Record the supplied signal build, connector cable, bearing positions and orientation. The 0.5% FS precision entry and 0.5% FS per 10 deg C temperature effect need to be assessed at the useful working loads and temperatures. Check the actual pin temperature against the -40 to +85 deg C operating reference and choose alloy steel or stainless steel for the joint environment. The sensor 200% FS safe-load figure is not an overload-test target for the joint or equipment.

For a longer bearing-joint reference, review the MV-LC0018 installation discussion. A shared nominal diameter cannot replace comparison of the bearing positions, end access, retention and actual rating.

Enquire about MV-LC0019 with the joint section, maximum pin reaction, controller input requirements and the exact connector and channel functions needed.
