• Stainless Steel Construction: Durable 24701 housing provides corrosion resistance and long-term reliability.
• Flexible Configuration: Features 0.5m cable, 3.0 in standoff adapter, and 3.6 in probe penetration for versatile installation.
• Multiple Probe Options: Compatible with 3300 XL 8mm probe featuring connector protector and approval options.
• Standard Mounting: 3/4-14 NPT mounting thread with one plug for simplified installation.
• Support Accessories: Compatible with 37948-01 probe support/oil seal for sleeves over 305 mm (12 in).
System Compatibility and Alternative Models
- System Compatibility: Contains an integrated 3300 XL 8mm reverse-mount proximity probe with a connector protector and a 0.5-meter cable length. It interfaces directly with Bently Nevada 3300 XL Proximitor Sensors, 3300 XL Extension Cables, and machinery protection architectures like the 3500 rack system.
- Alternative Model: 21000-34-05-30-036-04-02 Proximity Probe Housing Assembly.
- Key Differences:
Casing Material: The 24701 model relies entirely on a ruggedized 303 stainless steel main housing structure, whereas the 21000 model utilizes a lightweight aluminum body with a 304 stainless steel sleeve.
Weight Metrics: The 24701 stainless steel assembly has a typical unmounted mass of 1.8 kg (4.1 lb), whereas the 21000 aluminum variant is notably lighter at 1.1 kg (2.4 lb).

Individual Probe Sleeve for 21000/24701 Proximity Probe Housings
44382-AAA
| A: Measured Probe Sleeve Length | |
|
Recommendation Order in increments of 0.1 in (3 mm) |
|
The individual probe sleeve length does not include the distance from the end of the sleeve to the probe tip or the gap from the probe tip to the target material. If only the part number of the original housing is known, and the sleeve cannot be measured, use the following table to determine the sleeve length:
| AAA | Description |
|
Standoff adapter option from original housing (21000, CA21000, 24701, or CA24701 option C) plus Probe penetration option from original housing (21000, CA21000, 24701, or CA24701 option D) and 045 |
All housing AAA options except NSv and 11mm probes (options other than A:06, A:12, A:26, A:27, A:29, A:30, A:31, A:32, A:35, or A:36) |
