Product catalog summary

Overview
The document provides technical specifications and features of the brake calipers EV 028 FEM and EH 028 FEM, which are spring-activated and electromagnetically released. These calipers are designed for high efficiency and low power consumption, with a floating bearing to compensate for small misalignments of the brake disc.

Specifications

Brake disc diameter options range from 300 mm to 710 mm, with corresponding braking torques from 940 Nm to 2,580 Nm.
Clamping force is rated at 10,000 N with a response time of 150 ms.
Power consumption in open position ranges from 15 W to 19 W, and power when opening the brake is between 1,850 W and 2,500 W.
The calipers weigh 24 kg and are capable of 360 activations per hour at 20°C ambient temperature.

Features

Available with cCSAus approval.
Inductive proximity switch options for status indication and wear adjustment.
Manual adjustment for friction block wear.
Supply voltage options: 220 to 240 VAC and 380 to 480 VAC.

Ordering Information
An example order for a brake caliper with specific configurations is provided, illustrating how to specify supply voltage, electromagnet position, and brake disc thickness.

Technical Data

Theoretical friction coefficient used is 0.4.
Response time is defined as the duration from switching off the power supply to reaching 80% of maximum clamping force.
Actuation frequency requires at least 8 seconds between activations, with shorter frequencies available upon request.

Dimensions
Detailed dimensions for different brake disc thicknesses are provided, with values in brackets indicating adjustments due to friction block wear.

Features Code Brake Caliper with electromagnet E parallel or at right angles h Spring activated accommodate friction block wear central position Thickness of brake disc 10 ... 16 mm 12 or 18 ... 26 mm 25 Brake Caliper EV 028 FEM, supply voltage 400 VAC, electromagnet mounted in central position, thickness of brake disc 15 mm: The brake caliper EV 028 FEM or EH 028 FEM is a very compact and high efficient disc brake with very low power consumption. Its floating bearing compensates small misalignments of the brake disc. The attached electronic reduces the power consumption in open position automatically. • Available with cCSAus approval • Inductive proximity switch: "Brake released"-, "Brake closed"-status and/or "Friction block wear adjustment necessary" Technical Data The braking torques shown in the diagram are based on a theoretical friction coefficient of 0,4. * The response time is the duration from switching off the power supply to reaching 80% of the maximum clamping force (at Ta = 20 °C, setting: 100%). ** Shorter actuation frequency on request
