HMS J-, K- and Z-Series


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.
