Frequently Asked Questions
What is the AV87-11J1ATN pinout diagram reference?
The AV87-11J1ATN pinout features a 4-pin hybrid configuration. Pins 1 & 2 are dedicated to optical fiber transmission (Pin 1: TX optical signal, SMF-28 fiber; Pin 2: RX optical signal, SMF-28 fiber). Pins 3 & 4 provide electrical power (Pin 3: VCC Power, 16 AWG red; Pin 4: GND Ground, 16 AWG black). Continuity tests must be mapped directly to these wire designations to avoid signal cross-talk.
How do I derive mounting hole sizes for AV87-11J1ATN?
The recommended panel cutout for the Size 11 jam-nut mounting style is a standard circular profile with a diameter of 19.5mm (+0.1/-0.0mm) and a flat edge key-way width of 18.6mm to prevent rotation. Always consult the official CAD drawing to verify maximum material conditions before fabrication.
What are acceptable pass/fail thresholds for insertion loss and contact resistance?
For the optical channels, the maximum allowable insertion loss is ≤ 0.3 dB (typical 0.15 dB) measured at 1310/1550nm. For the electrical power contacts, the maximum allowable contact resistance is ≤ 5 mΩ (typical 2.5 mΩ). Anything exceeding these values constitutes a test failure.
What is the recommended mating torque for the AV87-11J1ATN jam-nut?
The recommended jam-nut installation torque to maintain an IP68 seal is 3.2 to 3.6 Nm (28 to 32 in-lbs). Over-tightening can strip threads or damage the conductive EMI gasket, while under-tightening compromises environmental sealing.
