The IP 68 Standard essentially states that dust and water under pressure are excluded.
Sensors are supplied with Top 68 plug at top but less cable. Cables with Top 68 receptacle are left in situ after a once off purchase. Maintenance costs are reduced with reliability being increased.
The system can be applied to 12mm, ¾", and 1" sensors. If the sensor is of a type with characteristics suitable for autoclaving, excluding the cable and receptacle the sensor with Top 68 plug can be autoclaved.
