This week’s Product Roundup highlights sensor-input connectors from leading suppliers.
ERNI’s M12 Right-Angle connectors were especially developed for use in industrial sensor applications and have a compact form factor that measures just 14mm in length to provide ideal solutions for sensor applications with small spaces and odd angles. These angled M12 sensor-input connectors are compatible with SMT assembly, which can offer considerable cost savings and quality improvements, and are equipped with a stop, formed by a collar, that allows the fully assembled PCBs to be pushed into the sensor tube up to the stopping point. They also offer snap-in functionality and anti-twist protection to ensure secure positioning within the M12 sensor tube and also employ an O-ring that shields against moisture and dust in harsh environments. ERNI’s angled M12 connectors support a variety of industrial sensors including level, distance, and pressure sensors.
HARTING’s range of circular sensor-input connectors includes a variety of threaded and push-pull M12 connectors, as well as the world’s first M8 D-code connectors for 100Mb/s Ethernet from the cloud to any sensor. These innovative M8 D-code connectors have a compact, robust, fully shielded, and environmentally sealed metal housing designed to support industrial miniaturization trends and reliably transmit both Cat 5 fast Ethernet and Power-over-Ethernet, which enables additional space savings by eliminating the need for a separate power connector. The series is standardized to PAS IEC 61076-2-114, which makes it intermateable with M8 connectors and sockets from other suppliers and compatible with existing passive and active equipment, and are equipped with IP67 sealing and continuous shielding for use in harsh industrial environments. HARTING’s M8 D-code sensor-input connectors are also 30% smaller than conventional M12 connectors and compatible with the PROFINET protocol as well as IEEE802.3.

Materion’s Alloy M25 is a high-strength, high-conductivity copper beryllium alloy that’s ideal for circular and coaxial connector contacts employed in heavy-duty, harsh-environment military, telecom, aircraft, and automotive applications, including 5G infrastructure and sensor-input connectors. Alloy M25 is based on Alloy 25, which provides both the highest strength of any copper beryllium alloy and considerably greater electrical and thermal conductivity than other high-strength copper alloys but has a slightly lower beryllium content and features the addition of lead, which enables excellent machinability. Available in rod and wire forms, Alloy M25 provides high tensile strength and high fatigue strength, which enables high-mating-cycle socket contacts, and also exhibits high resistance to wear, corrosion, galling, and stress relaxation. The material meets specifications and standards including MIL-C-2165 (rod), ASTM B196 (rod), ASTM B197 (wire), EN 12164 (rod and wire), and EN 1216 (wire).
