The 3300 XL Proximitor Sensor offers several improvements over previous designs. Its physical packaging allows you to use it for high-density DIN rail mounting. You can also mount the sensor in a traditional panel mount configuration, which shares the same 4-hole mounting "footprint" as the older Proximitor Sensor design. The mounting base for either option provides electrical isolation, eliminating the need for a separate isolation plate. The 3300 XL Proximitor Sensor is highly immune to RF interference, allowing you to mount it in a fiberglass enclosure without being adversely affected by nearby RF signals. The 3300 XL Proximitor Sensor's improved RFI/EMI immunity meets European CE Mark certification, eliminating the need for special shielded conduit or metal enclosures, reducing installation cost and complexity.

The 3300 XL’s SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen.

Extended Temperature Range Applications

For applications where the probe lead or extension cable may exceed the standard 177 °C (350 °F) temperature specification, an Extended Temperature Range (ETR) probe and ETR extension cable are available. ETR probes have an extended temperature rating up to 218 °C (425 °F). ETR extension cables are rated up to 260 °C (500 °F). ETR probes and cables are compatible with standard temperature probes and cables, for example, you can use an ETR probe with a 330130 extension cable. The ETR system uses the standard 3300 XL Proximitor sensor. Please note that when you use any ETR component as part of a system, the ETR component limits the system accuracy to that of the ETR system.
