New grippers from Norgren
A new range of grippers with a guaranteed life expectancy, and with the option of field repair, has been launched by pneumatics expert Norgren.
This ensures that the operator can easily detect critical conditions from long distances thus delivering advantage through maintained machine uptime The 33L features a self-diagnosis function to detect system errors thus allowing a higher degree of plant security.
The electronic lock feature prevents unauthorised personnel from changing the set up and the keypad with three user friendly buttons delivers advantage through reduced set up times and easy programming.
Featuring two transistor (or binary) output signals the 33L provides a switching output and a warning output that can also be programmed as an additional switching output thus delivering advantage through flexible user features.
The 33E is compact and robust in design thus delivering benefits to applications that suffer from space limitations and harsh operating environments.
Representing an economical solution the 33E features a relative pressure range from 0 to 400bar and delivers user versatility through the easy programming of switching points and the option of either thread or flange connections The 33E features one transistor (or binary) output signal and also has an electronic lock.
Both series are suitable for use with gaseous, liquid, aggressive and neutral fluids.
Connection is easy through the use of an M12 x 1 electrical connector and there are various different options for mounting.
The new pressure switch is extremely lightweight and offers +/-1.5% FS accuracy.
With a minimum switching life of 50 million cycles the switching point and the reset points are adjustable between 0 to 100% of FS.
The devices are shock proof to 25g, x-y-z, according to DIN EN60068-2-27 and vibration proof to 10g, 5 to 500Hz, in line with DIN EN60068-2-6.
Being free of lacquer impairing substances both devices features IP67 protection in accordance with DIN40050 and are suitable for an ambient temperature of -20 to +80C.
Switching time is less than 10ms (33L) and 3ms (33E) and each unit weighs only 60g.
