Core Insight: Recent datasheet aggregations and distributor listings indicate the 37-way APD endbell family is widely listed and commonly chosen for sensor and industrial circular connector assemblies.
Evidence: Multiple independent inventory records show frequent stocking and cross-listings.
Explanation: This prevalence makes precise confirmation of fit and sealing essential for designers and buyers who must avoid field failures.
Technical Breakdown: This article breaks down the 044-8597-000 endbell specs and compatibility so engineers can confirm fit quickly.
Evidence: The summary below synthesizes mechanical, material, and installation data drawn from standard APD-series documentation.
Explanation: Use this as a rapid-reference—044-8597-000 specs focus on dimensions, sealing, and interchange rules.
Product Overview & Intended Use
What the 044-8597-000 Endbell is and Common Applications
Point: The endbell is the cable-exit and strain-relief component for APD 37-way circular connectors.
Evidence: APD-series layouts show the endbell locates at the cable side, providing mechanical support, a sealed cable exit, and a mating surface to the connector shell. Explanation: Typical uses include industrial sensors, small actuator housings, and panel-mount assemblies.
Key Differentiators (Material, Finish, Color)
Point: Material and finish determine environmental suitability and longevity.
Evidence: Typical endbells in this class use glass-filled PA66 (nylon) with UV- and chemical-resistant additives. Explanation: This yields operating ranges from -40°C to ~95°C and improves resistance to oils and cleaners.
Full Technical Specifications
Mechanical Dimensions & Tolerances
Point: Accurate mechanical dimensions are the primary determinant of interchangeability. Evidence: Common listings show a nominal outer cable-exit face ~27 mm (1.06 in); typical machining tolerances are ±0.3 mm (±0.012 in).
| Parameter | Value | Unit | Tolerance |
|---|---|---|---|
| Outer Face Diameter | 27 | mm | ±0.3 |
| Cable Exit Angle | 180 | degrees | — |
| Recommended Panel Cutout | 1.06 | in | ±0.012 |
Materials, Thermal & Environmental Ratings
Point: Material selection and sealing features define long-term performance.
Evidence: Designs include an elastomer O-ring and a molded glass-filled nylon body, offering IP54–IP67 level protection. Explanation: Confirm operating temperature and UV resistance per manufacturer datasheet for demanding deployments.
Compatibility Matrix: Mating Parts & Shell Sizes
Mating Connector Types
| Connector Variant | Feature Fit |
|---|---|
| APD 37, Standard Shell | 180° Exit, O-ring Bore |
| APD 37, Thin-panel | Requires Spacer/Backing |
Cable OD & Strain Relief
Point: Cable diameter drives grommet selection.
Evidence: Compatible cable OD ranges span 6–12 mm (0.24–0.47 in). Explanation: Choose correct grommet orientation to minimize bend radius stress around the 37-contact arrangement.
Installation, Sealing & Testing Best Practices
! Step-by-Step Installation Checklist
- Inspect: Check endbell and O-ring for surface damage or debris.
- Measure: Confirm cable OD and select the appropriate grommet.
- Route: Guide conductors; seat grommet and endbell firmly.
- Tighten: Hand-tighten + 1/8 turn (consult torque specs for final).
Post-Installation Tests
Point: Post-install tests validate assembly reliability.
Method: Perform a bubble or pressure decay leak test (5–15 psi / 35–100 kPa), continuity checks, and insulation resistance checks per circuit.
