Accelerometer Gets The Measure Of Shocks

Measurement Specialties has released the Model 3700 accelerometer for impact, structural and transient shock testing. New from Measurement Specialties, the Model 3700 MEMS piezoresistive shock accelerometer was specifically designed for use in impact and shock testing environments and is packaged in a rugged stainless-steel housing. The accelerometer is available in ranges from +/-2000 to +/-6000g and is ideal for long-duration shock transient measurements.

The accelerometer incorporates mechanical overrange stops that offers shock protection greater than 10,000g. A PFA-jacketed cable, with customer selected cable length, provides reliable operation in transient environments.

SMT Connector Powers LEDs From Underside Of Board

Tyco has introduced the SMT thru-board connector, which supplies power from the underside of an FR4 or aluminium-clad PC board, eliminating issues of dressing wires on the top side of LED boards. The two-position through six-position connector surface mounts on top of the board, passing through the board to present an underside interface. The connector mates with standard Mini CT connectors. The inverted design allows simpler assembly and installation of solid-state LED lighting in architectural, residential and commercial applications. The Mini CT connector is rated for three amps per contact, on 24 AWG wire. A space-saving low-profile design and rounded corners minimise shadowing. The connector fits through a hole or notch in the board. High-temperature materials allow the connector to be reflow soldered, while a flat-top surface provides compatibility with vacuum pickup. The connector uses surface-mount hold-downs to provide stability during mating and unmating. With UL listing...

Electromechanical Relays (EMRs) vs. Solid State Relays Comparison (SSRs)

Image
Electromechanical Relays (EMR) Pros (Advantages) Lower initial cost compared to solid state relays. Provides complete electrical isolation. Tolerates high current & voltage transients. Insensitive to electromagnetic interference (EMI) / radio frequency interference (RFI). Higher open resistance (air gap). Lower closed resistance. Available with many poles/circuits (up to 8 or more). Many different circuit configurations available. Multiple packaging & feature options. Most typical failure mode is open. Electromechanical Relays (EMR) Cons (Disadvantages) Higher control (coil) power consumption. Contact arcing can cause pitting & eventual open/short failure. Contacts can be affected by corrosion, oxidation or contamination. Contact bounce possible due to shock & vibration. Generates electromagnetic interference (EMI) / radio frequency interference (RFI). Can be orientation sensitive. Can be affected by external magnetic fields. Subject to mechanic...
