HLS-440P

Automotive Hydrogen Leak Sensor

The HLS-440P automotive hydrogen sensor monitors hydrogen

leakage concentrations of 0 - 10% in air. The design fulfills Zone

2 requirements according to ATEX 100a. The predicted

concentration is transmitted to the host via the CAN bus

interface or with PWM output.

General Description

Type A:

The sensor shall measure the hydrogen concentration in high

humidity conditions, e.g. in the exhaust of a fuel cell system, to

ensure compliance with defined upper thresholds.

Type B:

The sensor shall measure the hydrogen concentration under

ambient humidity conditions, to ensure compliance with

defined upper thresholds.

Ordering Information and Content Guide appear at end of

datasheet.
