Outdoor Receiver
A receiver type with a sealed housing that can be mounted directly on the machine without needing a panel. AXI's LT200R receiver is in this class: with an IP67 housing, cable gland entry and a gasketed cover it is used in the SF200 set; the receivers of the ST200 sets are also IP67 outdoor type.
The value of an outdoor receiver is that it gathers the protection chain into a single part. It does not require a separate panel, separate gasket maintenance or in-panel heat management. Because it is mounted close to the machine the control cables are also shorter, which reduces noise coupling.
Three decisive points during mounting:
- Cable gland: the IP67 declaration is valid only when the gland is tightened with the correct cable diameter and the correct torque. Unused entries must be closed with blanking plugs.
- Cover gasket and screw torque: the gasket pressure must be distributed evenly and the screws tightened in a crosswise sequence.
- Orientation and position: if it is mounted with the cable entries facing downwards, the risk of water pooling and leaking in through the gland is reduced.
IP67 covers the immersion test, it does not cover the water jet test. For that reason do not clean a receiver with an IP67 housing with a high-pressure wash-down gun; if jet resistance is required, a dual rating declaration is what to look for.
On machines subject to vibration, include the terminal torques and the tightness of the gland in periodic maintenance; a gland that works loose quietly wipes out the protection rating.
