Yes. Internal encoders are offered in the 87, 81, 82 and 86 series of brakes.  Additionally, we can mount encoders on some of our other products.  Contact Stearns application engineers or customer service to discuss any options and application details for the best recommendation.

These brakes are available with the following side release options:

Standard T-handle Pull release

Standard Side Release Option – Modification 12​

• Vertical above motor mounting and/or IP 56 rating brakes
•  As a release option

Full Side Release with Quarter Circle Mechanical Lock Out Plate – Modification 50

• Used in portal and queue side cranes where brakes will be spring set while the motor-brake and load will be moved by rail, tire or tug. The brake is fully released with no residual drag, and requires mechanical lock in and out by a spring-loaded plunger. This option does not self-reset with power.

Full Side Release Option

• The brake is fully released with no residual drag. The under-cover pivot arm is longer than the standard release and fully seats the solenoid plunger into the coil which removes any brake spring force on the disc pack, brake gear hub and shaft. It is necessary to manually set and release.

Dead man or non-maintained release option – Modification 32

• Available with any release choice as an option. The brake requires constant force to keep the brake released and will re-set force with force removed. This option is used to slip loads or to keep brakes from staying in a released condition.

Undercover release – Modification 37

• No external release, a pull release is available when the cast cover is removed. This option is used to prevent undesirable or unintended brake release.

Yes. An internal encoder can be added to some existing brake models. Kits are available to retro-fit internal encoders.

For new brakes, many more models can be designed to include either external or internal encoders. Refer to the Stearns catalog (page  53), or consult factory.   

Only the stainless steel option of 56,700 is offered with a metal release knob.

Possibly, depending on the model. Contact Stearns for application assistance and advice on re-ordering or retrofitting any products in the field to meet your application requirements.
