INITIATOR WITH SWITCHING INDICATOR

Initiator with Switching Indicator |HJ-4101376 (XN5/220) – Proximity Switch for BFT & BHDT Waterjet Intensifier Pumps

The HJ-4101376 Initiator, also referenced as XN5/220, is a precision proximity sensor used in BFT and BHDT high-pressure waterjet intensifier pumps. The HJ-4101376 Initiator with switching indicator detects piston position within the hydraulic drive section and transmits signals required for accurate pump control and directional switching during intensifier operation.

Installed on the hydraulic actuator cylinder assembly, the HJ-4101376 Initiator continuously monitors piston movement and ensures synchronization of the hydraulic cycle. By providing precise position feedback, the sensor enables smooth switching between stroke directions, helping maintain stable pressure generation, consistent cutting performance, and efficient operation of the waterjet system.

The HJ-4101376 Initiator is engineered for the demanding conditions found in industrial waterjet cutting environments, where reliability and accuracy are essential. Proper initiator function helps prevent interrupted cycling, pressure fluctuations, reduced pump efficiency, and unexpected machine downtime. During routine maintenance and pump rebuilds, inspection or replacement of the initiator is often recommended to ensure uninterrupted operation.

The HJ-4101376 Initiator is commonly identified by OEM reference 4101376, and legacy reference XN5/220. Versions are available with or without a switching-status indicator depending on system requirements.
