B64G-NNK-AD1-RMN,NORGREN带活塞杆锁紧装置气缸
Reference number of switchings: 30/min. Reference temperature: +30°C
Spark quenching with diode with DC and inductive load:
Imax = 1.5 x Imax of table
Creepage and air paths correspond to insulation group B according to
VDE Reg. 0110 （except contact clearance of microswitch）.
* Gold-plating not required as it would decay. Max. perm. in-rush
current （appr. 30 ms） ACmake = max. 1.
** Gold-plating required （will not decay）.
† Lower value of critical voltage guarantees sufficient contact safety.
Lower voltages permissible under favourable conditions.
Reducer G 1/2 to G 1/4, externalSpark quenching with DC voltage （proposal）
1. Diode D in parallel to inductive load.
Observance of correct polarity （positive pole to cathode）.
Dimensioning specifications for quenching diode:
Rated voltage at diode: UD ≥ 1.4 x UV
Selection of a quick switching diode （recovery time trr < [200] ms）.
Rated current at diode: IR ≥ ILoad
2. RC link in parallel to load in parallel to switching contact.
Suited for DC abd AC voltage.
