binder has announced a short version of the 423 series: circular connectors in the M16 form factor with a length of approximately 47mm. When mated, these are offered as 2-pin to 19-pin variants and meet IP67 requirements. The product launch comprises short, shieldable cable plugs and sockets, each with cable clamp, in solder and crimp versions. Depending on the pins and connection type, the connectors are developed for wire gauges from 0.14mm2 (AWG 26) to 1mm2 (AWG 18). The rated values for voltage and current are specified as 32V to 250V and 3A to 7A, respectively. Cable outlets from 4.1mm to 7.8mm provide variability in the application.
Target applications for the series short version include test and measurement and automation technology that are subject to limited installation conditions. Also, precision instruments that have to provide accurate measurement results in confined and noisy environments benefit on the one hand from the particularly compact design of the connectors. On the other hand, the possibility of electromagnetic shielding is essential to stop interference signals from adjacent electronic circuitry from impairing the detection or transmission at the measuring device.
The aim of the product designers at the company was to develop the new M16 variants with as many standard parts as possible despite the specified degree of protection. To achieve IP67, they nevertheless required to integrate an additional lathe part. "Through dedicated and precise development, we have succeeded in establishing the same quality in a smaller form factor," product manager Sascha Doebel comments on the successful new development.
5G mobile communications, for example, is one of the innovation-rich application areas for its M16 connectors: here, AISG-compliant series products are utilised to connect devices in the network operators' antenna lines (Antenna Line Devices, ALDs). Besides customer requests, the company is now launching a short version of this product series.
The shieldable short version of the M16 series 423 is available in ten solder and five crimp male and female versions, corresponding to the different pin counts. They are all designed for more than 500 mating cycles.
The maximum wire gauges for solder products are rated at 0.75mm2 (AWG 18) for pin counts of 2 to 8; and 0.25mm2 (AWG 24) for 12-pin to 19-pin connectors. Depending on the pin count, the rated voltages are 32V or 150V depending on the pin count, the rated impulse voltages 500V or 1500V, respectively. The rated currents at 40C range from 3A to 7A. All solder products are equipped with brass contacts and bronze sockets and are specified for a temperature range from -30C to +95C. Housing and locking are made of nickel-plated brass.
The crimp products in the series are intended for wire gauges of 0.14 to 1mm2 or AWG 26 to AWG 18 (4 to 6 pins) and 0.14 to 0.75mm2 or AWG 26 to AWG 20 (7 to 8 pins). The rated voltages are 32V or 150V, the rated impulse voltages are 500V or 1500V, and the rated currents are 5A or 6A, respectively. The temperature range for the connectors with crimp termination extends from -40C to +100C. As with the solder versions, the housing and locking are nickel-plated brass.
