Working Principle

Advantage Highlights

1. PL d CAT4 safety certification meets global machinery safety standard for robot teaching operation
2. TPU shock-absorbent housing withstands frequent workshop accidental drops without damage
3. Variant HT401-222-40 physical jog wheel delivers higher precision manual positioning than touch-only models
4. Unique KONT. serial number enables full factory traceability for firmware matching and spare part replacement
5. Integrated CANopen safety bus eliminates external safety relay wiring cost

Applicable Industries

Installation Requirements

1. Connect spiral cable only to matching Keba main controller safety port, cross-brand adapter prohibited
2. 24V DC power supply must integrate safety circuit overcurrent protection fuse
3. Cable routing avoid sharp metal edges to prevent PUR insulation abrasion damage
4. Match main controller firmware version to KONT.26428 identifier before power-on startup

Operation & Maintenance Precautions

1. Do not disassemble dual safety internal circuit housing, disassembly voids safety certification
2. Clean touch screen only with static-free microfiber cloth, chemical solvent cleaners forbidden
3. Annual safety circuit functional test to verify deadman switch dual-channel cut-off performance
4. Replace spiral cable immediately if insulation cracking or wire exposure is observed
5. Store spare units in dry constant temperature cabinet when not in long-term use
