The following is a detailed analysis of the TS249, PS249B, JS-HH brake shoe wear switch, clearance protection switch, and brake safety switch used in the winch brake system protection detection equipment:

1、 TS249 brake shoe wear switch

Function and purpose:

Mainly used for wear detection of disc brake shoes in mine hoists.

Equipped with disc spring fatigue inspection function, it is a safety component of the hoist.

When the brake shoe is worn or the disc spring is fatigued, an alarm signal is issued to remind maintenance personnel to carry out maintenance to avoid accidents.

Main features:

High reliability and strong security.

The material is usually aluminum and resin, with a voltage of 220V and a current of 5A.

Manufacturer:

Luoyang Jiecan Electromechanical Co., Ltd., etc.

2、 PS249B brake shoe wear switch

Function and purpose:

Suitable for the detection and protection of brake pads in mine winches.

Detect and control the brake shoe clearance of the hoist disc brake.

Main features:

The rated voltage is 220V and the rated current is 3A (some information may display V3C rated voltage range of 36V and below, which may depend on the specific model or application scenario).

The contact type, contact resistance, insulation resistance and other parameters all comply with relevant standards to ensure the stability and safety of the switch.

It has an automatic reset function, making it easy to operate and maintain.
