SERIES GMLM MasterLatch ™ Q U I C K - D I S CO N N E C T M I C R O - D M asterLatch (GMLM) Quick-release locking Micro-D connector pairs are equipped with a precision latching and locking mechanism. The single thumb latch on the plug side actuates a pair of locking latches that mate quickly and reliably to GMLM receptacles. These TwistPin equipped, low-insertion-force connectors meet all the standard performance requirements of MIL-DTL-8513 including vibration, shock, and mating durability. Choose from 7 different insert arrangements from 9 to 51 way. The unique ergonomic latching mechanism can be easily activated with a thumb and forefinger grip even when wearing gloves, or when difficult access to connector pairs makes the use of jacking hardware and tools impossible. 1 2 3 4 5 1 2 8 6 7 8 1 1 9 210 311 4125136147158 9 pin 7 4 5 2 3 4 5 6 7 8 9 10 11 1 2 3 4 5 6 7 8 1 122 133 144 155 166 177 188 199 20102111 15 pin 9 21 pin 9 10 11 12 13 14 15 9 pin 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 25 pin 12 13 14 15 16 17 18 19 20 21 15 pin 114215316417518 6197 208 2192210231124122513 21 pin 14 15 16 17 18 19 20 21 22 23 24 25 25 pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 1 172 183194205 216227 238 2492510261127122813291430153116 1 202 213 224 235 246 257 268 279 2810291130 1231 1332 1433 1534 16 351736183719 31 pin 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 37 pin 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 37 pin 1 2 3 4 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 51 pin 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 31 pin 1 Easy-to-activate latching mechanism 9 10 11 12 13 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 1 Low insertion force TwistPin contacts Face view pin connector - Micro-D contact arrangements 1 62 73 84 9 5 6 3 Precision latch meets MIL-DTL-83513 vibration and shock 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 51 pin 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 For more information contact Glenair at 818-247-6000 or visit our website at www.glenair.com SERIES GMLM MasterLatch ™ Q U I C K - D I S CO N N E C T M I C R O - D How To Order GMLM MasterLatch™ Sample Part Number GMLM 2 L -25 P Product Series GMLM Glenair MasterLatch™ Micro-D Shell Plating 1- Cadmium 2 - Nickel 4 - Black Anodize 5 - Gold 6 - Chem Film Insulator Material L - LCP or PPS Contact Layout 9, 15, 21, 25, 31, 37, 51 Connector Type P - Single Ended Pin (Plug) S - Pin (Plug) Connector Both Ends Wire Gauge 4 - 24 AWG 6 - 26 AWG 8 - 28 AWG 0 - 30 AWG (30 AWG–Lab Only) Wire Type K - M22759/11 600 Vrms Teflon (TFE) J - M22759/33 600 Vrms Modified Cross-Linked Tefzel (ETFE) Wire Color Code 1 - White 2 - Yellow 5 - Color Coded 7 - Ten Color Repeating Cable Length In Inches 18 - 18 inches Socket WIRE LENGTH +1.0/-0.0 G K 7 -18 MasterLatch™ GMLM connectors are sold as prewired pigtails only, with 18 inch wire leads.
