Description
Bosch Rexroth 0608820115 | 4DMC160 SZ4 Transducer, New Surplus
Architect’s Product Breakdown
The Bosch Rexroth 0608820115 (4DMC160 SZ4) functions as a high-accuracy measurement transducer engineered specifically for advanced industrial fastening and tightening systems. Its primary responsibility is capturing precise torque and angle feedback directly from the spindle shaft during critical assembly operations. This feedback ensures strict adherence to quality control parameters in safety-critical manufacturing environments, such as automotive powertrain assembly.
The unit supports modular configuration setups, allowing engineers to implement a redundant measurement arrangement using a matching transducer paired with a redundant adapter. Maintaining uncompromised signal paths through this transducer is essential; any mechanical binding or electrical noise on the sensor line will distort torque values, potentially causing false rejects or unverified joint clamping forces on the production line.

Field Engineer’s Pitfall Guide (Unique Value)
- Mechanical Over-Torque Events: Subjecting the 4DMC160 transducer to dynamic spikes significantly exceeding its 160 Nm rating can permanently deform the internal strain gauges, rendering the sensor permanently uncalibrated.
- Transducer Cable Strain & Routing: Running sensor feedback cables parallel to high-voltage motor power lines without adequate separation introduces electromagnetic interference (EMI), causing erratic torque jitter on the controller display.
- Redundant Alignment Errors: When configuring a dual-transducer redundant setup using the adapter bracket, ensure mechanical pre-load is evenly distributed. Uneven mounting torque across the assembly flanges creates measurement drift between the primary and secondary channels.
QA & Testing SOP (Transparency)
- Visual & Origin Verification: Units are inspected for laser-etched Bosch Rexroth nameplates, uncompromised connector housings, and zero mechanical impacts on the drive shaft interface.
- Static & Dynamic Calibration: The transducer is mounted on a certified calibration rig, applying controlled torque steps up to 160 Nm to verify linearity, repeatability, and bridge output accuracy.
- Signal & Insulation Testing: Technicians check internal strain gauge resistance and insulation integrity to ensure zero signal leakage under operational stress.
- Anti-Static & Secure Packaging: Post-testing, units are wrapped in protective material and shipped in custom-molded, high-density foam cartons to prevent transit calibration shock.
Technical FAQ
- Can this transducer be used independently without a redundant adapter? Yes. The 4DMC160 SZ4 operates as a standalone high-precision measurement transducer, while also supporting optional dual-transducer redundant configurations.
- What causes sudden zero-shift or erratic torque readings during fastening? This typically points to a damaged signal cable, moisture ingress in the connector plug, or physical friction rubbing against the transducer body.
- Is factory recalibration required for surplus units? While New Surplus units retain original factory calibration, high-traceability applications often mandate a quick verification run on a certified torque bench prior to installation.
- What warranty is provided with a surplus unit? Units carry a standard 12-month replacement warranty backed by complete calibration verification testing.
