STA Series Wireless Torque Sensor Adaptor – Hybrid Type
STA Series Wireless Torque Sensor Adaptor for Interchangeable Head Torque Wrench – Hybrid Type
The STA Series Hybrid Type is a fixed head-to-head converter: one standard head shape goes in, a different standard head shape comes out, cast in a single body. It lets an Interchangeable Head Torque Wrench (IHTW) built for one head structure drive tooling built for another, while measuring torque and angle wirelessly in real time.
Key Features and Benefits
- Fixed One-Piece Head Conversion: no adaptor heads to swap – the input and output shapes are fixed at manufacture. Four input options, each convertible to 2-3 output types (dimensions for torque capacity under 120 Nm):
- Input Rectangular Male 9x12mm → Round (100.7 x 42.5 x 22.4mm), Dovetail (90.1 x 42 x 22.4mm), or Round “J” Shank (99.7 x 44 x 27.9mm) output
- Input Round Female Dia.16mm → Rectangular (100.7 x 44 x 28mm), Dovetail (100.2 x 44 x 28mm), or Round “J” Shank (108.7 x 44 x 27.9mm) output
- Input Dovetail Female → Rectangular (91.2 x 40 x 21.5mm), Round (101.2 x 42.5 x 22.5mm), or Round “J” Shank (99.2 x 44 x 27.9mm) output
- Input Round “J” Shank Male 0.425″ → Rectangular (99.7 x 42.5 x 22.5mm), Round (109.7 x 42.5 x 22.5mm), or Dovetail (98.2 x 42.5 x 22.5mm) output
- Torque Capacity Under 120 Nm (Standard Sizes): larger capacities and custom sizes available on request.
- Wireless Torque + Angle in One Unit: RF 2.4G (20m) or Bluetooth (15m); angle measured over 0°-360° at 0.5° resolution; static accuracy ±1% FSD (RF) / ±0.5% FSD (BT). RF version requires the DR-RF Dongle receiver.
- Built-In Recalibration Discipline: swapping the head, the STA, or the wrench requires recalibration for accurate torque, angle sensing, and control.
Specification:
- Configuration: Fixed head-to-head conversion (input head type differs from output head type)
- Input Options: Rectangular Male, Round Female, Dovetail Female, Round “J” Shank Male
- Torque Capacity: Under 120 Nm (standard); custom sizes on request
- Wireless: RF 2.4G (20m) or Bluetooth (15m)
- Static Accuracy: ±1% FSD (RF) / ±0.5% FSD (BT)
Features:
- Making it possible to control the torque and collect data of any “Interchangeable Head Torque Wrench”.
- Flexibility to expand the use of “Interchangeable Head Torque Wrench” with other structural types of heads.
- Patented design with wireless transmission for an easy adaptation or upgrade between various types of “Interchangeable Head Torque Wrench” and the heads.
- It is an easy-to-use torque tester, torque transducer, and angle gauge for torque and angle calibration.
- A laptop or tablet is used for setting, torque calibration, and data collection.
- Once the head, the STA transducer, or the wrench is replaced, calibration is required again to ensure the accuracy of torque, angle sensing, and control.
- After changing any of the heads, the STA, or the wrench, and recalibrating, a new indication prompts easy scale adjustment, while audible clicks are visible and torque data is collected.
- RF or BT wireless transmission options are available.
- RF version requires a DR-RF DONGLE signal receiver.
- Customized sizes are acceptable.

STA Coding Principle
Hybrid Type part numbers use the same coding format as the Standard Type: STA-[Input code][size]-[torque range]-[Output code][size], e.g. STA-RM-1-0005-RF-1. Input/output codes: RM/RF = Rectangular Male/Female, OM/OF = Round Male/Female, DM/DF = Dovetail Male/Female, JM/JF = Round “J” Shank Male/Female, TM/TF = Tohnichi Male/Female. Torque range codes span 0005 (0.5-5 Nm) through 1200 (120-1200 Nm).
