Omron D4BL Elektromagnetický blokovací spínač Napájení pro odemknutí

Omron D4BL Series Solenoid Interlock Switch, 115V Contact AC Voltage, IP67 - D4BL-1DRA

This solenoid interlock switch provides electrically controlled access restriction for safety doors and guarded machinery in industrial settings. Designed for harsh environments, it integrates a solenoid mechanism to lock or release guards, enabling remote control of access while maintaining safety-circuit integrity. The unit is suitable where a compact, sealed interlock is required alongside conventional wiring practices.

Features & Benefits

• IP67 protection for dustproof and temporary immersion resistance
  Die-cast aluminium housing for robust environmental protection
  Two normally closed safety contacts to maintain circuit interruption
  Power-to-lock and power-to-unlock capability for flexible control logic
  Accepts PG13.5 conduit for standard cable-gland entries
  Screw terminals supporting straightforward electrical termination

Applications

• Suitable for safety door interlocks on automated production lines
  Ideal for guarding access on packaging and assembly machines
  Used for controlled access on conveyor transfer points
  Suitable for integration into factory safety control panels
  Used for hazardous-area exclusion zones with non‑certified equipment

What electrical supply options does it support?

It accommodates AC at 115V for Coil operation and DC at 24V for control circuits where required.

What is the expected switching capacity for control circuits?

The contact rating is 300 mA, suitable for low-current safety-signal applications and interlock logic.

How are cables terminated within the unit?

Wiring is secured via screw-type terminals and routed through a PG13.5 conduit entry for sealed connections.

Is the enclosure material appropriate for industrial workshop conditions?

The enclosure is MADE from die-cast aluminium, providing mechanical durability and resistance to impact in typical industrial environments.

Notes

Actuators must be purchased separately. Stock no. 746-7208 incorporates an easy-to-see indicator for monitoring.
