Description

This is the high temperature version of the S200A heat sensor, a fixed temperature device set at 78 °C and classified Type BS. Low mass thermistors together with microprocessor technology handle the sensing for fast response, and the unit addresses on the System Sensor Protocol as an analogue addressable field device.

A B501AP base is required. With that base the assembly weighs 88g (inc base), stands 61mm tall and spans 102mm, while the White PC/ABS moulding presents terminals rated for a 2.5mm² conductor. It operates on 15 to 32Vdc, standby current reaching 200 µA at 24Vdc when the sensor is not communicating and 300 µA at 24Vdc with the LED blinking once every 5s, and 3.5mA at 24Vdc is taken by the LED. The sensor holds its rating from -30°C to +70°C.

Read the full technical description

The 52051HTE-26 is an S200A heat sensor for high temperature duty, fixed at 78 °C and classed Type BS, finished in white and needing a B501AP base. Sensing is by a fixed temperature analogue addressable design that employs low mass thermistors together with microprocessor technology for fast response.

The sensor belongs among System Sensor Protocol Analogue Addressable Field Devices, operating on 15 to 32Vdc. With no communications the sensor sits at 200 µA at 24Vdc, and enabling LED blink at once every 5s lifts maximum standby current to 300 µA at 24Vdc, with a further 3.5mA at 24Vdc drawn by the LED.

Physically the sensor is a PC/ABS moulding in White weighing 88g (inc base). Fitted to a B501AP base it stands 61mm high with a 102mm diameter, and its terminals take a maximum wire gauge of 2.5mm². Declared working conditions are -30°C to +70°C and relative humidity of 10 to 93% (non-condensing).
