There are two versions of the product, 0520 and 0520T but this is not explained anywhere and the pictures for the two versions are mixed. I placed a first order and got the 0520T which was the version I needed. I placed a second order and got the 0520, and the shop refused to reimburse or even simply acknowledge the problem. Also, shipping was extremely slow. I would avoid that vendor.
Very compact and small solenoid. Works very quiet. Spring soft. Core is not high accuracy, but this is not critical. After 5-10 seconds of operation, the coil heats up, but it is written in the description. Overall - very good. Thanks!
