Industrial Applications

1. Industrial Pump Control Panel Status Indicator

Using the blue integrated LED indicator and the 1 NO auxiliary contact, this assembly is integrated into control boards for industrial induction pumps. The 1 NO contact switches when the operator activates the push button, while the 220V AC supply powers the blue LED, signaling operational status.

Problem Solved

Solves the problem of lack of visible system feedback in noisy environments, ensuring operators can visually confirm a successful pump start sequence directly on the 22mm panel.

2. Heavy-Duty Machinery Reset and Warning Sub-Assembly

The robust chromium-plated metal construction and IK06 mechanical impact resistance rating make this light block body ideal for conveyor systems and stamping presses. Placed within a standard 22mm mounting hole on heavy machine operators' desks, the 1 NO contact is wired to a reset relay, while the blue LED acts as a warning or sequence complete indicator.

Problem Solved

Prevents premature failure of indicator units due to physical shocks and harsh industrial environments, offering high mechanical durability via its metal fixing collar.

3. Main Power Distribution Panel Alerting

Installed inside low-voltage switchboards or distribution boxes, this assembly uses its 220V AC rating to directly connect to power lines. Its IP20 protection safeguards technicians during panel maintenance and testing.

Problem Solved

Addresses the risk of accidental shock during maintenance procedures by integrating IP20 finger-safe terminals, while providing high impulse withstand voltage (6 kV) protecting the pilot indicator against grid transients.
