The HLM Heavy Duty Die-Cast Hinge Safety Interlock Switch (Part Number: 139014 - Model: HLM) manufactured by world-leading IDEM Safety Switches Ltd (United Kingdom) is designed to be mounted directly at the pivot point of hinged access doors and machinery guard covers, detecting guard opening angles and immediately opening safety circuits.

PRODUCT OVERVIEW & SPECIFICATIONS (PART NO: 139014):
- Part Number: 139014
- Model: HLM (Heavy Duty Die-Cast Hinge Safety Interlock Switch)
- Shaft Type: Solid Stainless Steel Shaft engineered for extreme torsional and mechanical fatigue resistance.
- Enclosure Construction: Robust die-cast metal alloy housing finished in heavy-duty red industrial polyester coating, offering high impact resistance against falling metal debris and shop floor collisions.
- Contact Block: Positive break safety contacts (IEC 60947-5-1) guaranteeing positive mechanical separation without contact sticking.

KEY ADVANTAGES:
- Exceptional Tamper Resistance: Because the operating mechanism is mounted concentrically with the door hinge pin, personnel cannot defeat or bypass the safety circuit using tape, bypass keys, or external magnets.
- Ultra-Sensitive Trip Angle: The positive-break safety contacts actuate within 3° to 5° of door opening, cutting machine drive power before the operator can reach internal hazardous zones.
- IP67 Ingress Sealing: Dust-tight and resistant to water submersion, delivering dependable performance in heavy cutting oil, debris, and coolant splash environments.
- High Functional Safety Compliance: Certified to Category 4, PLe (ISO 13849-1) and SIL 3 (IEC 62061).
