At electronica 2016, Pickering Electronics will champion its innovative series of ultra-high-density reed relays for use in the construction of high-density matrices and multiplexers. The Series 115, 116, and 117 of small single-pole (1 Form A) reed relays have identical pin configurations, allowing for a common printed circuit board but giving designers a range of switch ratings according to which part is fitted.
Because the reed switches are vertical within the package, a common footprint with a board area of a mere 3.8 × 6.6 mm is possible. Only the profile height changes with increasing power or current ratings.
Dimensions and specifications are:
• Series 117: Height of 9.5 mm; rated at 0.5 A switching at 5 W.
• Series 116: Height of 12.5mm; rated at 0.5 A switching at 10 W.
• Series 115: Height of 15.5 mm; rated up to 1.0 A switching at 20 W.
Double-pole (2 Form A) versions are also available in the Series 116 and 117.
All feature instrumentation-grade reed switches with sputtered ruthenium contacts, suiting them for low-level or “cold” switching applications. They have an optional internal diode across the coil connections for back-EMF suppression and implement the company’s SoftCenter construction in addition to internal mu-metal magnetic screen. Mu-metal offers high permeability and low magnetic remanence, and eliminates problems related to magnetic interaction.
