The 2N2222AUA (TX - Obsolete, TXV - NRND) is a hermetically sealed ceramic surface mount general purpose switching transistor. The four pin ceramic package is ideal for designs where board space and device weight are important design considerations. The “UA” suffix denotes the 4 terminal leadless chip carrier package, type “A” per MIL-PRF-19500/255. Typical screening per MIL-PRF-19500/255. The burn-in condition is VCB = 30 V. PD = 400 mW, TA = 25° C, t = 80 hrs. Refer to MIL-PRF-19500/255 for complete requirements. In addition, the TX and TXV versions receive 100 % thermal response testing. When ordering parts without processing, do not use the TX or TXV suffix.

The OPF1414 series fiber optic transmitters contain a high speed 840 nm GaAIAs LED. This LED in conjunction with the package lensing is designed to efficiently couple light into multimode optical fibers ranging in size from 50/125 μm up to 200/230 μm. The high coupling efficiency of the LED and lensing allows the devices to be used at low current drive levels thus decreasing the power consumption and increasing system reliability. The consistency of coupling varies by less than 5 dB from part to part which reduces the dynamic range requirements of the receiver. The high power (-16.0 dBm into 50/125 μm) OPF1414 was designed for small fiber applications or where there are large fixed losses such as in systems that contain star couplers or in line connectors.

The Shunt Gapmeter Model LPCB is approved for regular monitoring and testing of sprinkler systems by the LPCB, Loss prevention Certification Board, under their ‘Rules for Automatic Sprinkler Installations’, in the UK, and by many equivalent organizations in other countries. Model LPCB provides a compact, robust, direct reading flowmeter for 50mm-200mm pipelines and is suitable for use in horizontal or vertical pipes.

A complete VA flowmeter consists of a glass flow tube and float scaled to the flow units required, and a frame to provide the end block supports and to cover and protect the tube. The NGX series frames use flow tubes with nominally 100mm long scales, whereas the smaller LGX frames use flow tubes with nominally 30mm scales. To choose a complete flowmeter select the frame code required, and separately specify the fluid flow range needed on the flow tube scale.

The OEM pressure sensor is a high performance, cost effective solution available in standard ranges from lOOmbar to 600bar. All ranges are available in gauge or absolute format. It is ideal for continuous use in applications where the pressure medium is wet and corrosive and long term stability is of prime importance.
