Rectangular Connectors - Headers, Male Pins

Introduction

STMM-112-01-S-D-SM-P refers to a type of rectangular connectors, which are commonly used to assemble electronic circuits. It is designed for information connection in a wide range of systems like telecom, office automation, medical, industrial control, automotive and consumer markets. The connectors contain a number of male pins, which have an operating temperature range of -40°C to +105°C.

Application field of STMM-112-01-S-D-SM-P connectors

STMM-112-01-S-D-SM-P connectors are mainly used in two kinds of application field, the first one is power supply field. In power supply application field, the STMM-112-01-S-D-SM-P connectors provide efficient connectivity and reliable power supply system. Its 11-pin plug design could fit 11 20 AWG wire with 0.1-mm2 pitch size. In addition to this, its polarized shell could prevent contact trouble caused by misalignment of plug and mating. The second application field of STMM-112-01-S-D-SM-P connectors is signal transmission field. In signal transmission application field, the STMM-112-01-S-D-SM-P connectors will be used more strictly. As the signals it transmit may directly affect the application’s working process, so this STMM-112-01-S-D-SM-P connector need to provide reliable contact and transmission to avoid signal interference. The contact resistance of male pins should be guaranteed lower than 4 milli-ohm and the operating voltage should be higher than 250V. Furthermore, the contact protection must be maintained.

Working principle of STMM-112-01-S-D-SM-P connectors

STMM-112-01-S-D-SM-P connectors are based on the principle of signal transmission. The 11-pin male pins in the plug structure of the connector are uniform, which can be inserted into the corresponding female pins on the other side. The power can be transmitted through the connector to the corresponding device. The contact between the plug terminals is made of BeCu or Silver. When the connector is unplugged, the surface of the contact can still be in good contact with the other side through the elasticity of the contact material, so a good connection is also established, to ensure the transmission of the signal from the plug side to the corresponding female side.

Conclusion

STMM-112-01-S-D-SM-P connectors are a type of rectangular connectors, which are mainly used in power supply and signal transmission fields. These connectors have 11-pin plug design and polarized shell to ensure efficiency and reliability. Its working principle is based on the principle of signal transmission, and the contact resistance of male pins should be low and the operating voltage should be high to guarantee reliable transmission. Thus, these connectors provide users with reliable and efficient connectivity.
