Product information

The Bently Nevada 21000-28-05-00-077-03-02 is an aluminum proximity probe housing with a 3300 XL 8mm hazardous-area-approved probe, 0.5m cable, 7.7-inch penetration, and fitting option 03 (plug, reducer, and cable seal grip).

Features and benefits

7.7-inch probe penetration (DDD=077) – Reaches deeper targets while staying under the 12-inch sleeve support limit.
Fitting option 03 included – Provides one NPT plug, one reducer, and a cable seal grip for flexible conduit connections.
Selectable hazardous area approvals (AA=28) – Allows use in intrinsically safe or explosion-proof environments.
No standoff adapter (CC=00) – Simplifies installation with direct mounting for most machine cases.
0.5m probe cable (BB=05) – Short cable length reduces signal loss and eases routing in tight spaces.
3/4-14 NPT mounting thread (FF=02) – Industry-standard thread ensures compatibility with common machine ports.

FAQ

Q1: What is the probe penetration length for part number 21000-28-05-00-077-03-02?
A1: The penetration length (Option D) is 7.7 inches (196 mm), coded as 077 in increments of 0.1 inch.

Q2: Does this assembly include a standoff adapter?
A2: No, CC=00 means no standoff adapter is included; the probe mounts directly into the housing.

Q3: What conduit fittings come with the EE=03 option?
A3: It includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for cable diameters of 1/8–3/16″, 1/4–5/16″, and 5/16–3/8″.

Q4: Is sleeve support required for this 7.7-inch penetration?

Q5: Can this housing be used with a 3300 XL NSv probe instead?
A5: No, AA=28 specifies a 3300 XL 8mm probe. For an NSv probe, select AA=26 or 27 from the ordering table.
