2 Product description
The COMBISTOP type 28 brake is an electromagnetically actuated dual-surface
spring-applied brake for dry running. It can be used for applications where high de-
mands to the degree of protection are made.
The brake is optionally completely closed on the back (version G10/G20) or prepared
for the installation of tacho generators (type G1T/G2T) or equipped with a shaft sealing
ring (version G1W/G2T).
Using the optional hand release (version G20, G2T and G2W) the brake can be manu-
ally opened even in the event of a malfunction.
