Bosch Rexroth R978835256 Float Level Switch Assembly

Bosch Rexroth R978835256 Float Level Switch Assembly is a magnetic float‑operated level sensor designed for integration with Bosch Rexroth hydraulic systems and fluid reservoirs. As part of the ABZMS‑41 family, it provides two level‑switching contacts and configurable options for temperature output and a 4–20 mA analog signal, depending on the variant. The sensing element relies on a magnetically actuated float, which triggers the level contacts when the liquid falls below the preset point, with actuation typically referenced to the lower banjo bolt within a 60 mm (2.36 in) range to suit banjo‑mount installations. For exact electrical connections, switching points, mounting options, and installation details, consult the ABZMS‑41 data sheets (such as RE 50223‑B, Edition 2023‑10).
