12、 - Continued. REQUIREMENTS Dimensions and configuration: See figure 1. Material: Guide pins, type X guide sockets, jackscrews, and jacksockets shall be made of corrosion resisting stainless steel in accordance with ASTM A581/A581M or ASTM A582/A582M, passivated in accordance with SAE-AMS-2700, or sh
13、all be corrosion resistant copper nickel alloy (61 2 percent copper, 25 2 percent nickel, 2.5 percent maximum other, and the balance zinc) and shall have a brinell hardness of 145 to 175. Type Y guide sockets shall be beryllium copper in accordance with ASTM B196/B196M or ASTM B197/B197M, nickel pla
14、ted in accordance with SAE-AMS-QQ-N-290, class 02, 50 to 150 microinches. Plating: The contact plating shall be in accordance with MIL-DTL-55302, or gold in accordance with ASTM B488, type II, code C, class 1.27, over nickel plating in accordance with SAE-AMS-QQ-N-290, class 02, 50 to 150 microinche
15、s in the engaging area and gold in accordance with ASTM B488, type II, code C, class 0.51 or type III, code A, class 0.51, over nickel plating in accordance with SAE-AMS-QQ-N-290, class 02, 50 to 150 microinches in the termination area.

Contact resistance: The average contact resistance of all contacts measured shall not exceed 0.007 ohm, and no individual contact pair shall
17、have a resistance exceeding 0.015 ohm. Dielectric withstanding voltage: Sea level: 750 volts rms. High altitude: 250 volts rms at 70,000 feet. Current rating: 3.0 amperes maximum per contact. Polarization: Type X regular, guide pin and socket, full round (see figure 1). Type Y, adjustable “D” shaped
18、 guide pin and socket (see figure 1, detail A). All connectors are supplied in the -1 polarized position. For other than OEM use, connectors may be repolarized by using M55302/57-01 spanner wrench and M55302/190-01 guide pin and guide socket kit. When guides are removed and reinstalled in another po
19、sition, apply Loctite 83-CV or equivalent on the threads. Ordering connectors in other than the -1 polarized position may be done by the OEMs by placing the desired polarized position in brackets three spaces after the Part or Identifying Number (PIN)on the purchase order. Example: M55302/191A100Y -
20、32. Polarization pins and sockets shall be adjusted to any desired configuration by spanner wrench (M55302/57-01). Ordering connectors in the -1 polarized position without Loctite 83-CV or equivalent applied may be done by placing a “-0” in brackets three spaces after the PIN on the purchase order.
21、Guide sets, as installed, shall withstand 7 ounce-inches backoff torque applied through the guide set mounting nut. M55302/190-01 kit: Consists of one type Y ”D” shaped guide socket and one type Y “D” shaped guide pin and two spanner nuts. Provided by IHSNot for ResaleNo reproduction or networking p
