TelemotiveA2261-0Antenna End Plate for Radio Remote Control Receiver Enclosure, Marked LR29

Product Description

What this part is

A Telemotive A2261-0 antenna end plate, marked LR29. Telemotive builds industrial radio remote control systems for cranes, hoists and process machinery. This is the antenna end plate from the receiver enclosure: the end panel that carries the antenna mounting provision and closes off that end of the receiver housing.

What is in the box — read this first:
This is the end plate only. It is a mechanical enclosure part. There is no antenna supplied with it, no receiver, no radio board, no output module, no cable and no connector. If you need the whole receiver, or the antenna itself, this is not that item — this is the plate the antenna mounts through.

Decoding the part number

A2261-0 — the Telemotive part number for the plate. Also written A22610 and A2261.LR29 — a marking carried on the plate itself, quoted here because buyers matching a plate against the one in hand search on it.

Why the antenna end plate matters more than it looks:
Two reasons this gets replaced rather than bodged. First, environmental sealing: the receiver enclosure on a crane lives in dust, heat and washdown, and the end plate is part of what keeps that out of the radio electronics. A cracked, drilled-out or improvised plate is how water gets to a receiver board. Second, antenna position: the plate fixes where the antenna sits relative to the enclosure and its ground plane, and radio range on an industrial receiver is genuinely sensitive to that. Relocating an antenna to a convenient hole elsewhere in the box is a well-known way to turn a reliable radio into an intermittent one, which on a crane is a safety problem rather than an inconvenience.

Fitting notes

Isolate the crane or machine at the mainline disconnect and lock off before opening the receiver — the enclosure carries live control voltage even though this part does not. Compare the plate against the one you are removing before you commit: check the antenna mounting hole size and position, the bolt pattern and the plate outline, since Telemotive used several enclosure sizes across the receiver ranges. Transfer or renew the gasket and any sealing washers rather than reusing a compressed one, and torque the fixings evenly so the seal seats. Refit the antenna in its original orientation, then function-test the radio at the far end of the intended working area, not just next to the crane, before returning the machine to service.

Quantity and configuration

One end plate. Not included: the antenna, antenna base or connector, coaxial cable, gasket, fixings, receiver enclosure, receiver boards and modules, transmitter, and system documentation.

Interchange guidance

Match the part number and check it physically against the plate in hand — on enclosure hardware the fit is the specification. Plates from other Telemotive receiver ranges, including the later inteleSmart TR12 and TR24 generation, are different enclosures and will not bolt up. Also written A22610, A2261, A-2261-0, A2261 0 and LR29, and found under the Telemotive, Magnetek and Columbus McKinnon names.
