EPIC® INDUSTRIAL CONNECTORS: HOW THEY COMPARE TO ALTERNATIVES

EPIC® and alternative rectangular connectors share similar core specifications: ratings up to 1000V and 82A, IP65 to IP68 protection and modular insert systems compatible with DIN standard housings. The key difference is manufacturer integration—EPIC® connectors are engineered and produced by LAPP, the same company that produces ÖLFLEX® cables, enabling matched cable-connector solutions from a single source with unified technical support across ASEAN.

For design engineers evaluating heavy-duty connectors, datasheet comparisons reveal only part of the picture. Assembly time, cable compatibility, total cost of ownership and local support networks influence long-term performance as much as voltage and current ratings. This guide examines what you should compare when selecting rectangular connectors, where EPIC® specifications sit relative to industry standards and why the cable-connector relationship matters more than most procurement teams realise.

What should you compare when evaluating heavy-duty connectors?

Rectangular heavy-duty connectors from any reputable manufacturer will meet baseline electrical and mechanical requirements. The evaluation criteria that separate an adequate choice from the right one go beyond voltage and current ratings. Focus your comparison on seven areas:

Electrical ratings. Verify rated voltage (up to 1000V for power applications), rated current per contact (up to 82A for EPIC® H-BE series) and rated impulse voltage. These values must match your circuit requirements with a safety margin—not just meet them at the limit.

IP protection class. Standard rectangular connectors typically achieve IP65 when mated. If your application involves washdown, submersion or high-pressure cleaning, you need IP68 or IP69 ratings. EPIC® ULTRA connectors deliver IP68 protection when mated, with IP69K-rated variants available in select series — check the specific MPN datasheet for your target IP class.

Contact count and flexibility. Fixed-layout connectors work for simple power circuits. When your design combines power, signal and data transmission in a single connection point, modular systems (like EPIC® MH) let you configure the exact contact arrangement you need—up to 250A power modules alongside Cat.7 Ethernet (or fiber optic LC) and D-sub signal inserts in one housing.

Termination method. Screw termination is familiar but time-consuming. Crimp connections are faster and vibration-resistant. Cage-clamp termination offers tool-free installation. EPIC® connectors support all three methods across the range, so you choose based on your assembly environment rather than being forced into one approach.

Assembly time. This is where connector selection has the largest impact on project cost. Modular EPIC® MH connectors reduce assembly time by approximately 65% compared to wiring multiple circular connectors—from roughly 60 minutes to under 25 minutes for a typical 24-contact installation. That time saving multiplies across every machine you build.

Certifications. For ASEAN export markets, you need connectors with UL, CSA and VDE certifications. EPIC® connectors are tested to IEC 61984 and carry UL 1977 and VDE 0627 approvals. Confirm that any alternative connector carries equivalent certifications for your target markets.

Manufacturer ecosystem. This is the criterion most engineers overlook during initial evaluation and most regret ignoring later. We address it separately below.

How do EPIC® specifications compare to industry standards?

EPIC® rectangular connectors comply with DIN 43652 housing standards and are intermateable with equivalent DIN-type connectors from other manufacturers. This means you can adopt EPIC® without having to redesign your panel cutouts or modify existing enclosure specifications.

The comparison below shows EPIC® specifications alongside typical industry-standard values for DIN-type rectangular connectors:

Rated voltage: EPIC® up to 1000V | Industry standard up to 830V–1000V
Rated current: EPIC® up to 82A (H-BE) / 250A (MH modular) | Industry standard up to 82A
IP protection (mated): EPIC® IP65 / IP68 / IP69 (ULTRA) | Industry standard IP65
Contact count: EPIC® 3 to 280 | Industry standard 3 to 216
Termination: EPIC® screw, crimp, cage-clamp | Industry standard screw, crimp
Housing: EPIC® die-cast aluminium alloy | Industry standard die-cast aluminium alloy
Temperature: EPIC® -40°C to +125°C | Industry standard -40°C to +125°C
Certifications: EPIC® UL 1977, VDE 0627, IEC 61984 | Industry standard UL 1977, VDE 0627

Values represent typical ranges across product families. Confirm specifications per part number for your application.

On core electrical and mechanical specifications, EPIC® connectors match the performance of established alternatives. The differences emerge in three areas: IP protection range (EPIC® ULTRA extends to IP69), contact flexibility (modular system reaches 250A) and termination options (cage-clamp availability across the range).

EPIC® range overview: standard, ULTRA and modular systems

The EPIC® portfolio covers industrial connector requirements from standard control cabinet connections to extreme-environment applications. Three product tiers address different performance needs:

EPIC® H-BE and H-B series—standard rectangular. The core range for control cabinets and machine interfaces. Available with 6 to 24 contacts, screw or crimp termination, aluminium alloy housings with IP65 protection when mated. These connectors handle the majority of industrial power and signal connections and are directly intermateable with equivalent DIN-type housings.

EPIC® ULTRA—harsh environment. When standard IP65 protection is insufficient, EPIC® ULTRA connectors deliver IP68 (submersion to 10 bar for 30 minutes) and IP69 (high-pressure washdown at 80°C). Stainless steel and high-grade polymer housing options suit food processing, pharmaceutical and outdoor installations. The ULTRA range uses the same contact inserts as the standard series, so you specify harsh-environment housings without having to change your wiring design.

EPIC® MH modular system—configurable connections. The modular frame accepts interchangeable modules for power (up to 250A), signal, data (Cat.5e to Cat.6A Ethernet) and pneumatics in a single connector housing. Modules click into the frame without tools, reducing assembly time significantly compared to wiring separate circular connectors for each signal type. This system is particularly valuable for machine builders who need to transmit power, control signals and industrial Ethernet through one connection point.

The full EPIC® range includes over 1,800 connector and cordset variants available through the JJ-LAPP eShop, covering rectangular, circular (M12 to M23), modular and solar connector families.

Why does connector-cable integration matter?

Most connector evaluations treat the connector as an isolated component. In practice, the connector is one half of a connection system—the cable is the other half. When these come from different manufacturers, three problems emerge:

Specification mismatches. Cable outer diameter must fall within the connector’s cable gland range for proper strain relief and IP sealing. When you source cables and connectors independently, confirming mechanical compatibility becomes your responsibility. Tolerance mismatches between manufacturers can reduce IP rating or cause premature cable jacket damage.

Split accountability. When a connection fails, the cable manufacturer points to the connector and the connector manufacturer points to the cable. Resolving warranty claims across two suppliers costs engineering time and delays replacements.

Fragmented technical support. Design questions that span cables and connectors—“Which ÖLFLEX® cable works with this EPIC® connector in a drag chain?”—require a single engineering team that understands both products.

LAPP eliminates all three problems by engineering and producing both ÖLFLEX® cables and EPIC® connectors. When you specify LAPP connectivity for your machine design, cable-connector compatibility is guaranteed at the design stage. Technical support covers the full connection system and warranty accountability sits with one manufacturer.

For OEMs building machines for ASEAN markets, this integration extends to pre-assembled cable harnesses through ÖLFLEX® CONNECT. Factory-assembled, 100% tested harnesses using matched LAPP cables and connectors arrive ready for installation—reducing your commissioning time by up to 40%.
