SIEMENS 1FU1050 HKZ101S1 (261) (HALL SENSOR)

The SIEMENS 1FU1050 HKZ101S1 is a Hall‑effect speed/tacho sensor commonly utilized in Siemens SIMOTICS servomotors. It provides a non-contact NPN open‑collector output, powered by 4.5–24 V DC, delivering reliable analog pulse signals proportional to rotational speed. Designed to operate in harsh industrial environments, it functions across a wide temperature range (typically −40 °C to +150 °C), resists vibration and dirt, and requires minimal maintenance. The sensor is compact and easily mounted on the motor housing or drive shaft system. Ideal for applications needing robust, real-time speed feedback without optical discs or glass components.
