Industrial TT-77-F-MS-2T 400 Electronic Temperature Sensor

The Thermotronik TT-77F-MS-2T is a tank-mounted electronic temperature sensor with a built‑in 4‑character LED display, designed to monitor and display fluid temperatures inside tanks and reservoirs. The MS brass version houses a Pt100 Class B element (DIN EN 60751) and provides two freely programmable PNP switching outputs (2T) with a maximum of 0.5 A per output. It operates on 10–30 V DC (nominal 24 V) and uses M12 4‑pin connectors for the base, with a G1/2 flange for mounting, and carries an IP65 enclosure rating. Standard installation lengths run 280, 370, or 500 mm, featuring a brass immersion tube and tank‑mounted configuration; the sensor measures from -40 to +100 C, while the ambient operating range is -20 to +70 C.
