Definition of Vibration, Humidity, Terminal form, Weight and

2.11 Vibration: vibration strength and vibration stability is divided into two indicators.

Vibration stability: refers to the vibration value of time closed contact is opened and OFF contact closure time in the case where the predetermined time, the relay can bear vibration amplitude generally "mm" and a vibration frequency "Hz" composition representation.

Vibration intensity: refers to the case where the structure is not damaged the relay, the relay can withstand vibration value generally indicates a vibration amplitude of "mm" and a vibration frequency combinations "Hz". See test methods

2.12 Humidity: relay means operable under normal humidity, typically at a relative humidity "RH%" FIG.

2.13 Terminal form: the form of the lead end of the relay, also shows the field of application. Usually the form of pigtails PCB (printed circuit board), line type (THT), surface mount (SMT), plug-in, quick-connect (QC) type and combination thereof.

2.14 Weight: weight of the relay.

2.15 Packaging: refers to the protection mode of the relay body. Generally divided into open-type, type dust cover, solder formulations, plastic type and the sealed type, see chapter "relay selection principle" of 3.1 "encapsulation."
