Amphenol has released a series of line print terminal (LPT) connectors designed for use in harsh environments. Featuring an aluminum shell design, the connectors accept wire gauges from 22 AWG/0.34mm² to 12 AWG/3.5mm², have rapid positive coupling and 5 key/keyway mating to ensure that users don’t mismate the connectors when plugging them into receptacles.

The LPT series is waterproof to the IP67 standard and self-extinguishing to UL94 V-0. The connectors can withstand 500 mating cycles and have an operating temperature range of -40°C to +125°C. The connectors are available in five shell styles, including box mounting receptacle, jam nut receptacle, straight plug, wall mounting receptacle and cable connecting receptacle.

Kester has launched the NP560, a no-clean, lead-free, halogen-free solder paste. It provides paste transfer efficiencies of 0.50 to 0.55 AR and is capable of printing and reflowing 01005 components—even in air—with minimal graping behavior. In addition to improvements in its stability and product performance, NP560 has an improved voiding standard for PCB assembly and provides low voiding performance.

Information about pricing and availability can be found on Kester’s website.

Littelfuse MOSFETs

Littelfuse and Monolith Semiconductor have partnered to develop two 1200V silicon carbide (SiC) n‑channel, enhancement-mode MOSFETs. The LSIC1MO120E0120 and LSIC1MO120E0160 SiC MOSFETs provide low on-resistance (RDS(ON)) levels of 120 milliohms and 160 milliohms, respectively. Both are designed for use as power semiconductor switches in a range of power conversion systems, and provide improvements over their silicon MOSFET counterparts in terms of blocking voltage, specific-on resistance and junction capacitances.

“These new SiC MOSFETs provide power converter designers with a state-of-the-art alternative to traditional silicon-based transistors,” said Michael Ketterer, product marketing manager for Power Semiconductors at Littelfuse. “Their inherent material characteristics and fast switching capabilities offer a variety of design optimization opportunities, including increased power density, higher efficiency and the potential for lower bill-of-materials costs.”

Masterbond has introduced the EP42HT-3AO, a two-component, moderate viscosity epoxy system with increased flow properties. It is ideal for small to moderate size encapsulating, potting and casting applications. It is also effective in bonding fragile components that require a low coefficient of thermal expansion.

EP42HT-3AO is designed to optimize heat dissipation properties and improve the quality and reliability of electronic devices subjected to thermo-mechanical stresses.This compound combines a low CTE of 13-16x10-6 in/in/°C with a high glass transition temperature (Tg) of 140-150°C. This epoxy system has a thermal conductivity of 11-12 BTU•in/ft²•hr•°F [1.59-1.73W/(m•K)].

Additional technical specifications are available on Masterbond’s website.

SCHUNK Magnetic Chucks

SCHUNK has released the MAGNOS magnetic chucks, which provide low-deformation workpiece clamping, free accessibility and a fast workpiece change. To provide additional operating comfort, all SCHUNK MAGNOS square pole plates are equipped with a default status monitor. The monitor displays the current clamping status continuously, even when, for example, the magnetic chuck has been disconnected from the control and is in a pallet storage with clamped workpiece.

By selecting the appropriate connection cable, both small magnetic chucks with 4-PIN connectors, as well as large magnetic chucks with 7-PIN connectors, can be actuated. Equipped with plug connectors, each cable can be easily exchanged. Moreover, it is possible to assign vacant slots at any time with additional magnetic chucks. To ensure process reliability in automated applications, it is also possible to monitor each individual magnetic chuck.
