HIGH DENSITY RECTANGULAR CONNECTORS with FIXED CONTACTS Positronic Industries connectpositronic.com High Density Rectangular Size 22 Contacts Qualified to MIL-DTL-28748 SGM SERIES IEC Publication 807-1 Telecommunication U.L. File #E140980 O NIC INDU Di * EC For RoHS options see page 21. 5/ U rE Compliant IES RoHS TR POS R S IT Ideal applications for the SGM Series are where low weight and high density are requirements. The high reliability of "closed entry" female contacts insures numerous couplings of the connector without substantial degradation of contact resistance. SGM Series connectors are preferred for use in the aerospace, avionics, telecommunications, instrumentation, medical and robotics industries. * pe SGM Series connectors are high reliability, high density, rectangular connectors qualified to MIL-DTL-28748 specifications. The SGM Series offers solder cup, wrap post and straight solder termination styles, and is intermateable with Positronic SMPL and SGMC series connectors. Thirteen connector variants, four through 75 poles, are offered. Contact spacing is 0.094 inch [2.39mm] between centers, and contact diameters are 0.030 inch [0.76mm], rated to five amperes per contact. A complete array of mounting, locking, polarizing and shrouding accessories is available for the SGM Series. For details, see the High Density Rectangular Connector Accessories section. rec tive 2002 /9 SGM SERIES TECHNICAL CHARACTERISTICS MILITARY SPECIFICATIONS: Qualified to MIL-DTL-28748/7 and MILDTL-28748/8.
