Product catalog summary
Overview: The document provides technical specifications for the DRFS ¼" -w-S torque sensor, designed for use in screwing techniques compliant with DIN EN ISO 9000 standards. It features torque ranges from 1 Nm to 20 Nm, with a hex drive and angle rotation identification.
Key Features:
  • Universal attachment to standard electric screwdrivers.
  • Rigid connection between sensor and screwdriver, lockable in any position for easy handling.
  • Maintenance-free due to non-contact measured value transmission.
  • High accuracy through frequency modulation and DMS principle.
  • High interference immunity due to amplified active signal.
  • Integrated chip for sensor detection with evaluation units GMV2 and ValueMasterBase.
Technical Specifications:
  • Supply voltage: 12 V DC ± 10%.
  • Power consumption: < 200 mA.
  • Voltage output: 0 to ± 5 V.
  • Internal resistance: 100 Ω.
  • Operating temperature: 0 - 60 °C, compensated range: 5 - 45 °C.
  • Protection: IP 40.
  • Connection: 2.5m cable with 12-pin connector.
Mechanical Specifications:
  • 1/4" Hexagonal drive DIN 3126 (ISO standard 1973-1975).
  • Mechanical overload varies by torque range, with 100% for 1-12 Nm and 30% for 20 Nm.
Angle Option (w):
  • Max revolutions: 3000 min-1.
  • Output: open-collector with internal pull-up of 10 kΩ (5 V level).
  • Resolution: 1° with detection of direction of rotation.
Ordering Information: The sensor model is specified by torque range and connection type, with various screwdriver compatibility options (e.g., Delvo, HIOS, Elekta).
Available Accessories: Supply and display units such as ValueMasterBase, GMV2, and ValueView, along with cables.
