A1050 Aluminum Head 5 % 40cm NTC Temperature Sensor 2.2k 3950 24AWG
Quick Detail:
Absolute accuracy ± 0.7 °C
Linear output within 0.2 °C
Resolution better then 0.005 °C
Duty Cycle output
Calibrated on chip
TTL, CMOS compatible
Temperature range 175 °C (-45 to +130 °C)
Directly connectable to data input of microprocessor
Easy multiplexing of multiple sensors
Description:
The temperature sensor is a sophisticated full silicon temperature sensor with a
digital output. The one wire output (duty-cycle modulated) can be directly connected to all
kinds of micro-controllers without the need of A/D conversion. The temperature range is –45
°C to 150 °C. The high resolution (< 0.005 °C) makes the sensor useful for high precision
applications. The sensor is available in various housings like T018, T092, T0220 and for high
volume production in SOIC. Special housing can be manufactured on request.
Applications:
Heater systems
Measuring instruments
Washing machines
Overheating protection
Appliances
