The LPIL-7-MP-IM is an Impulse Compatible Low Profile Micro in-line subsea connector, 7-pin male (pins) face, rated 250 V DC/AC rms at 5 A per contact (max 35 A per connector). Dimensionally compatible with Teledyne Impulse LPMBH/LPIL hardware for direct drop-in field replacement, the flat low-drag body is designed for AUV sensor payloads, gliders and compact oceanographic instruments, and is rated to 690 bar / 10,000 psi mated (approx. 7,000 m).

Key Design Features
Low-profile, low-drag body: the flat connector profile presents minimal cross-section to
water flow — significantly reduces drag on AUV hulls, glider fairings and ROV sensor racks versus standard
circular connector bodies.
High contact density in a compact body: 7 contacts in a flat rectangular footprint that
fits tight instrument racks and sensor clusters.
Wet-mateable: more than 500 wet mating cycles with wiper seals protecting the contacts.
Gold-plated contacts: corrosion-immune, stable low-resistance paths over the full operating life.
Flexible marine build: high-grade rubber body suited for repeated dynamic bending in
instrument cables and pigtails.
SubConn Compatible: drop-in dimensional compatibility with Teledyne Impulse LP hardware.

Typical Applications
AUV sensor and payload connections, underwater gliders and profiling floats, compact oceanographic instrument packages (CTD, dissolved oxygen, fluorometer), ROV-mounted instrument sensors, subsea cameras and lighting on compact inspection ROVs, deep-sea landers and benthic observatories, acoustic modems and hydrophone arrays, diver instrumentation.
Notes for Selection
Impulse Compatible: dimensionally compatible with Teledyne Impulse LPMBH/LPIL hardware — verify mating thread and contact gender before installation. Install the locking sleeve before deployment. Store with dummy connectors installed; rinse with fresh water after seawater exposure. Open-face pressure rating 480 bar / 7,000 psi.
Custom configurations available
Titanium coupling nut and shell hardware for weight-sensitive AUV / glider applications, factory-terminated
assemblies with customer-specified PUR cable OD, matched BH + IL + DC sets, and batch or per-unit hydrostatic
pressure test certificates can be specified to order. Send us your drawing or requirement for a quotation.
