The Pickering Series 113-2-A-5/2D is a magnetically screened single-in-line reed relay designed for high-density applications. It features a Form A configuration, allowing it to energize to make, with a power rating of 10 Watts and a maximum switching current of 0.5 Amps at 200V. The relay has a compact footprint of 0.15 inches by 0.5 inches and a height of 0.35 inches, making it suitable for space-constrained designs. This relay is encapsulated in a plastic package with a high resistivity resin, achieving an insulation resistance greater than 10^12 ohms. It includes an internal mu-metal magnetic screen to minimize magnetic interaction, which is critical in densely packed circuits. The standard coil voltage for this model is 5V, with a coil resistance of 150 ohms. The relay is also tested for dynamic contact resistance, ensuring reliable performance in various applications. Engineers looking for a reliable, compact relay for automatic test equipment or other applications requiring high insulation resistance and minimal magnetic interference may find this product suitable for their needs.
The Pickering Series 113 is a range of magnetically screened single-in-line reed relays that require a board area of only 0.15 inches (3.8mm.) by 0.5 inches (12.7mm.) The Form A (energize to make) versions retain the 10 Watts, 0.5 Amps rating associated with larger relays. The changeover version has a 3 Watts rating.
These relays require less than half the board area of the more usual 0.2 x 0.8 inch devices and have a height of only 0.26 inches (6.6mm.) for the 1 Form A and 1 Form C types and 0.35 inches (8.9 mm.) for the 2 Form A type.
The Series 113 is encapsulated in a plastic package using a very high resistivity resin to achieve an insulation resistance greater than 1012 ohms for the Form A types. The relay has an internal mu-metal screen which totally eliminates the risk of magnetic interaction problems. An unscreened device mounted on this pitch would have an interaction figure of around 40 percent. Relays of this size without magnetic screening would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 113 have a typical interaction figure of 5 percent.
3, 5 and 12 Volt coils are standard, with the option of an internal diode. 1 Form A, 5 Volt coils have a resistance of 500 ohms and may be driven directly from TTL logic.
