HMS J-, K- and Z-Series
The HMS Series are single element thermopile sensors in small or miniature TO-46 or µ-TO packages. They are primarily used for temperature measurements. Like all our sensors, the HMS sensors support a fully modular concept. You can choose a thermopile sensor chip and a top mounted infrared filter according to your application. Additionally, the sensor can be equipped with an optional thermistor providing temperature reference.
Due to the small size of the µ-TO "Z" package, the HMS Z11 is not available as a sensor module with an integrated ASIC for signal processing.
All other sensors can be equipped with an integrated ASIC for analog or digital signal conditioning which facilitates the application.
Features and Benefits
- Small TO-46 or tiny µ-TO package
- 3 different thermopile sensor chips available
- Large number of filter options
- Optional thermistor temperature reference
- Large operating range -20°C to 120°C
