Nicomatic DMM connectors meet MIL-DTL-83513G performance standards and offer greater modularity compared to other MIL-SPEC connectors, such as Micro-D or Sub-D. Engineers can customize the number of pins (both in rows and contacts), contact type (signal, power, and coaxial/RF), and mounting type (board-to-board, board-to-cable, cable-to-cable, or panel-mount). DMM connectors also offer space savings and provide electromagnetic and mechanical shielding.
The D53C is a new captive screw option developed by Nicomatic for all its DMM connectors. Its "mate-before-lock" mechanism securely positions and aligns the connector before the screw is tightened. Because it's captive, the locking hardware remains attached to the connector, even when unscrewed; this prevents the screw from being lost and causing damage to the equipment. Using the D53C is as simple as:
• Step 1: Align the connectors
• Step 2: Push until stopped
• Step 3: Tighten the fasteners with a Hex 2 tool
“Developed in response to customer feedback, this new, simple ‘mate-before-lock’ type fastening hardware is ideal for field applications, such as changing battery packs or payloads on UAVs, where technicians and operators need a quick, secure, and reliable connection method that helps prevent damage to contacts,” says Phil McDavitt, UK Managing Director at Nicomatic. “The captive nature of the screw also makes it impossible for it to fall out or get lost. Meanwhile, engineers working on electronics on the test bench benefit from the convenience of being able to repeatedly connect, pair, and disconnect elements of their design with ease, without having to tighten screws each time.”.
The D53C can also work with salt spray, oil-based and synthetic lubricants, and coolants, as well as temperatures from -55 °C to +125 °C, and a shock severity of up to 100g for 6 ms in a sawtooth pattern (no signal interruption > 1 µs) and a vibration severity of up to 10 to 2000 Hz/15g/3 axes/12 cycles per axis (no signal interruption > 1 µs).
