Description
The ifm Electronic TT series are high-precision temperature probe sensors (thermistors / Pt100 / Pt1000 elements) designed for direct insertion into pipes, tanks, and process vessels. Models such as TT1281 (Pt1000, M12 connector), TT5081 / TT5050 (process thermometers with G½ process connection), and TT7281 / TT0281 / TT0291 (compact probes) are widely used in food & beverage, water treatment, HVAC, and machine building for reliable temperature monitoring. The TT series offers stainless steel housings, high ingress protection (IP67/IP68/IP69K on selected models), and analog or IO-Link compatible electronics depending on variant.
Key Features
- Sensor Element: Pt100 / Pt1000 / NTC — model dependent (TT1281 = Pt1000 typical)
- Process Connection: G½” (DIN 11851 type on hygienic variants), M8/M12 plug or cable outlet
- Temperature Range: Typically -50 °C … +150 °C (probe), some variants up to +200 °C
- Protection: IP67 to IP69K (stainless steel stem)
- Output: 2-, 3-, or 4-wire; some versions with integrated transmitter (4…20 mA / IO-Link — check suffix)
- Country of Origin: Germany
Typical Model Reference
Model | Sensor Type | Process Conn. | Cable / Plug | Typical Application |
|---|---|---|---|---|
TT1281 | Pt1000 (Class B) | Plain stem / G½ option | M12 × 4-pin plug (often) | Tank / pipe insertion, PLC analog IN |
TT5081 | Pt100 / Pt1000 | G½” process conn. | Fixed cable or M12 | Water / glycol temp. in process skids |
TT5050 | Pt100 / Pt1000 | G½” / clamp (hygienic opt.) | Cable / Plug per suffix | Food & beverage (CIP/SIP capable on some) |
TT7281 | Pt1000 or NTC | Compact stem | M8 plug or cable | Machine-local temp. monitoring |
TT0281 / TT0291 | Pt1000 | Short stem | M12 plug | Compact machine / hydraulic oil temp. |
⚠️ Important: ifm TT model suffixes define sensor element (Pt100/Pt1000/NTC), cable length, connector type (M8/M12), and whether an electronic transmitter is built in. Always confirm the exact suffix (e.g.TT1281—followed by alphanumeric code) before ordering to match your PLC analog card or ifm IO-Link master.
