Snap-on TTC4 Torque Transducer, 1/4″ Drive, 5-50 in-oz

Description

Small screws in electronics and instrument work often need only a few centinewton-meters. However, a general tester cannot read such low values well. The Snap-on TTC4 torque transducer fills that gap. In short, it is the 1/4 in drive, 5-50 in-oz sensor in Snap-on’s TTC range.

Snap-on TTC4 torque transducer data

• Drive: 1/4 in square.
• Range: 5-50 in-oz, or about 3.5-35 cN·m.
• Accuracy: ±0.5% of indicated test value, from 10% to 100% of the range.
• Bench top mounting bracket: TTC3421.

In addition, Snap-on states that every TTC transducer comes with the correct adaptor for its range.

Where the TTC4 fits in a test stand

Snap-on’s TTC2000 and TTC2800 master systems read transducers from 5 in-oz up to 2,000 ft-lb. In that line-up, then, the TTC4 sits at the very bottom. Each transducer also carries a memory chip, so the monitor can identify it and keep its calibration data. As a result, you can swap sensors without a long setup.

Choosing between the TTC4 and its neighbors

Pick the sensor whose range brackets your tool, because the stated accuracy only applies from 10% of full scale. For example:

• TTC4: 5-50 in-oz, so it suits the lightest drivers.
• TTC5: 15-200 in-oz.
• TTC6: 4-50 in-lb.
• TTC65: 15-150 in-lb.

So if your screwdrivers run above 50 in-oz, the TTC5 or TTC6 makes a better match. Snap-on also lists a TTC75002 kit for testing torque screwdrivers on 2000 and 2800 series systems.

Care for the TTC4 low-range sensor

A 50 in-oz sensor has little margin. Therefore, never exceed its rated torque, and avoid side loads when you seat a bit or an adaptor. Then store it in a dry case. Also follow Snap-on’s advice on periodic recalibration checks, since the whole stand depends on this reading. Snap-on’s catalog says TTC transducers ship individually serialized with NIST-traceable certificates; confirm with Lost in HCM what comes with your unit.

Order the Snap-on TTC4 torque transducer

Lost in HCM supplies the TTC4 and writes the quote, while SMK Vietnam lists it as a partner product. Mention your monitor model, so Lost in HCM can check the match. Then request a TTC4 quote from Lost in HCM. You can also browse torque testers and calibration systems, see torque screwdrivers, or contact SMK Vietnam.

TTC4 questions

What range does the TTC4 cover?

It reads 5-50 in-oz, so it covers about 3.5-35 cN·m.

Which monitors read the TTC4?

Snap-on lists the TTC transducer range for its TTC2000 and TTC2800 master torque calibration systems. Still, ask Lost in HCM to confirm the match for your monitor.

Does the TTC4 need a mounting bracket?

For bench work, Snap-on pairs it with the TTC3421 bench top mounting bracket.
