1. A wheel speed sensor for a utility vehicle, comprising:
an active pulse sensor,
a housing to at least partially enclose the active pulse sensor, and
a protective cap to at least partially cover the housing;
wherein the wheel speed sensor has at least one component to adapt a temperature resistance capability of the wheel speed sensors so that the wheel speed sensor is usable in a high temperature environment, and
wherein the active pulse sensor includes a magnetic sensor as the component to adapt the temperature resistance capability of the wheel speed sensor so that the wheel speed sensor is usable in the high temperature environment, and
wherein the wheel speed sensor has a region adjacent the active pulse sensor, and wherein the region has a thermal insulation medium that has a lower thermal conductivity than a thermal conductivity of a material of the housing.
